What’s New in Cardiac MRI?

June 06, 2026 · 88 articles · 20 research themes · covering May 30, 2026 – June 06, 2026

Overview

The dominant thread across this week’s papers is the move from “one-size-fits-all” cardiovascular assessment toward mechanism-based, imaging-anchored risk prediction and targeted care. Multiple studies use cardiac MRI (and PET/CMR hybrids) to quantify subtle tissue injury and remodeling—such as LA strain after STEMI, microvascular obstruction heterogeneity, pulmonary transit time and strain across coronary syndrome stages, and diffuse fibrosis markers (native T1/ECV)—to refine prognosis beyond conventional clinical variables.

A second major theme is methodological acceleration: new CMR acquisition and post-processing workflows (e.g., optical gating without ECG, real-time oxygenation-sensitive MRI, vendor-robust scar visualization, and automated segmentation) plus a growing ecosystem of AI/radiomics tools for segmentation and outcome prediction. Together, these efforts aim to make advanced imaging more reproducible, scalable, and clinically usable—while also addressing equity, as highlighted by AI approaches for earlier ATTR-cardiomyopathy detection in underdiagnosed populations.

Finally, the digest underscores the expanding “cardio-systemic” frontier—where inflammation, immune therapies, genetic disease, and comorbid physiology (sleep apnea, extreme exercise, kidney disease, congenital syndromes) are increasingly linked to cardiac structure/function via multimodality imaging. Across myocarditis/immune-related injury, amyloidosis (including imaging endpoints for radiotherapy and tafamidis monitoring), and cardio-oncology surveillance frameworks, the common goal is earlier detection and better matching of interventions to the patient’s underlying biology.

Coronary Artery Involvement in Kawasaki Disease and Multisystem Inflammatory Syndrome in Children: Imaging, Risk Stratification, and Long-Term Cardiovascular Considerations.

This review article examined coronary artery involvement in Kawasaki disease (KD) and multisystem inflammatory syndrome in children (MIS-C), focusing on imaging findings, risk stratification, and long-term cardiovascular considerations. It summarizes that KD most commonly causes persistent coronary dilation and aneurysm formation, whereas MIS-C coronary involvement appears less frequent and often transient with different long-term implications. The synthesis helps clinicians anticipate coronary risk trajectories and informs long-term cardiovascular follow-up strategies in pediatric inflammatory syndromes.

Treatment of Premature Ventricular Contractions: A Review of Medical Therapy, Catheter Ablation, and Emerging Treatments.

This review article studied the comparative evidence for treating premature ventricular contractions (PVCs), covering medical therapy, catheter ablation, and emerging treatments. It concludes that treatment selection should be guided by symptom burden, PVC frequency, ventricular function, and underlying structural heart disease, with CMR often used for tissue characterization during diagnostic evaluation. The review provides a clinically oriented framework for managing PVCs to prevent PVC-induced cardiomyopathy and reduce arrhythmia-related morbidity.

Right Ventricular Metabolic Adaptation to Afterload and Heterogeneous RV-Pulmonary Arterial Coupling in Pre-Capillary Pulmonary Hypertension: An FDG-PET/CMR Study.

This FDG-PET/CMR study investigated right ventricular (RV) metabolic adaptation to afterload and heterogeneous RV–pulmonary arterial (RV-PA) coupling in patients with pre-capillary pulmonary hypertension. The authors found that higher pulmonary vascular resistance (PVR) was associated with increased RV glucose metabolism and impaired RV-PA coupling, consistent with early maladaptive metabolic remodeling before overt structural changes. These results link PET-measured RV metabolism with coupling physiology, supporting earlier identification of RV deterioration risk in pre-capillary PH.

Monitoring Myocardial Oxygenation Response to Respiratory Maneuvers Using Real-Time MRI.

This study evaluated real-time MRI methods to monitor myocardial oxygenation response to respiratory maneuvers using oxygenation-sensitive (OS) MR without relying on ECG triggering. In ten young healthy female volunteers on a 3T scanner, two real-time sequences (including RT bSSFP and RT FLASH) plus a semi-automated analysis workflow enabled continuous, motion-robust assessment of oxygenation dynamics. The approach could streamline myocardial oxygenation testing and reduce manual workload and ECG-related limitations in future clinical and research applications.

Mitral Regurgitation Assessment Using a Novel Automated 3D Color Flow Quantification: Comparison With 2D PISA and CMR.

This retrospective study evaluated a novel automated three-dimensional color flow quantification (3D Auto CFQ) tool for quantifying mitral regurgitation (MR) severity and regurgitant volume (RVol) in 185 consecutive patients undergoing transesophageal echocardiography (TEE), comparing it with 2D proximal isovelocity surface area (PISA). 3D Auto CFQ, which integrates real-time 3D TEE color Doppler with a fluid-dynamics-based model, showed feasibility and improved performance versus conventional 2D PISA for MR quantification (with results reported against CMR as the reference in the truncated abstract). More accurate, geometry- and single-frame–independent MR quantification could improve clinical decision-making for MR severity assessment and treatment planning.

Unique Shield: An Obstructive Huge Tricuspid Pouch Associated With Ventricular Septal Defect Developing Into Adulthood.

This JACC Case Reports report describes a 43-year-old woman with an obstructive huge tricuspid valve (TV) pouch associated with a perimembranous ventricular septal defect (VSD) that persisted into adulthood, using cardiac magnetic resonance (CMR) to define anatomy and flow. The TV pouch caused significant right ventricular (RV) inflow obstruction with bidirectional flow into the pouch but no effective communication with the RV, preventing a significant left-to-right shunt and pulmonary arterial hypertension (PAH). Surgical partial excision of the pouch and VSD closure (with TV preservation) highlights a rare congenital mechanism of RV inflow obstruction that can be missed without detailed multimodality imaging.

Pericardial Hemangioma: A Case Report and Updated Literature Review.

This case report and literature review describes a 57-year-old man with a hypervascular pericardial mass evaluated with coronary computed tomography angiography, cardiac magnetic resonance (CMR), and DOTATATE PET/CT plus plasma catecholamines. Although CMR suggested an epicardial tumor contiguous with the visceral pericardium with suspicion for an intrapericardial paraganglioma, normal DOTATATE PET/CT and catecholamines led to surgical excision and histopathologic confirmation of pericardial hemangioma. Recognizing this diagnostic mimic and using an organized multimodality workup can prevent misclassification of rare pericardial tumors and guide appropriate surgical management.

​EuroNet-PHL-LP1: Complete resection or low-dose chemo for pediatric low-risk nodular lymphocyte-predominant Hodgkin lymphoma.

This prospective phase III trial (EuroNet-PHL-LP1) studied treatment strategies for children and adolescents with early-stage nodular lymphocyte-predominant Hodgkin lymphoma (nLPHL), comparing complete lymph node resection with active surveillance versus low-intensity, anthracycline-free CVP (cyclophosphamide, vincristine, prednisone) chemotherapy for unresectable disease. The study found that patients with completely resected lymph nodes could be managed with surveillance, while those with unresectable nodal disease received three cycles of CVP as a lower-intensity approach. If confirmed in full results, this could reduce exposure to anthracyclines in pediatric low-risk nLPHL while maintaining favorable event-free survival.

Diagnostic challenges in isolated cardiac sarcoidosis.

This review article examined the diagnostic challenges of isolated cardiac sarcoidosis (iCS) in terms of how clinicians integrate multimodality imaging, endomyocardial biopsy, and molecular testing while excluding extracardiac disease. It highlights that cardiac magnetic resonance (CMR) and positron emission tomography (PET) provide complementary assessment of myocardial inflammation, fibrosis, and ventricular function, improving diagnostic confidence despite inherent limitations of each modality. Improved diagnostic algorithms for iCS are clinically important because iCS is associated with worse prognosis and is fundamentally a diagnosis of exclusion.

Muscular dystrophy cardiomyopathy in pediatric cardiac MRI.

This article presents pediatric cardiac magnetic resonance (CMR) findings in a case of muscular dystrophy cardiomyopathy, specifically in Duchenne muscular dystrophy (DMD), where ECG and echocardiogram were normal. The key point is that CMR detected clinically relevant myocardial involvement that can guide prognosis and treatment even when standard screening tests appear reassuring. Using CMR in pediatric DMD may enable earlier identification of cardiomyopathy and more informed risk stratification.

Myocarditis in idiopathic inflammatory myopathies: serologic and clinical correlates in a single-center registry.

This single-center retrospective registry study evaluated 142 adults with idiopathic inflammatory myopathies (IIM) to correlate serologic and clinical features with cardiovascular magnetic resonance (CMR)-confirmed myocarditis using the 2018 Lake Louise Criteria at diagnosis and during follow-up. It assessed diagnostic performance of high-sensitivity cardiac troponin I (hs-TnI) and quantified the independent prognostic impact of myocarditis relative to interstitial lung disease (ILD). Establishing these correlates and prognostic contributions can improve detection and risk stratification of myocarditis in IIM patients.

Quantitative 99mTc-PYP SPECT/CT at 90 minutes improves diagnostic stratification in transthyretin cardiac amyloidosis.

This retrospective single-center study assessed whether quantitative 99mTc-PYP SPECT/CT at 90 minutes post-injection improves diagnostic stratification for transthyretin cardiac amyloidosis (ATTR-CM) beyond standard planar imaging at 60 and 180 minutes in 170 patients with suspected cardiac amyloidosis. The key finding was that adding quantitative 90-minute SPECT/CT increased diagnostic specificity, particularly addressing the common ambiguity of Perugini score 1 on planar imaging. More accurate noninvasive staging of ATTR-CM can streamline patient selection for confirmatory testing and disease-modifying therapy.

Examination of elevated myocardial extracellular volume and exercise capacity in pediatric Fontan patients at moderate altitude.

This retrospective cohort study investigated the relationship between CMR-derived markers of diffuse myocardial fibrosis—native T1 and extracellular volume (ECV)—and exercise capacity in pediatric Fontan patients at moderate altitude, compared with healthy controls. It tested whether elevated myocardial extracellular volume and altered T1 metrics correlate with reduced exercise tolerance, aiming to link diffuse fibrosis to clinically meaningful Fontan physiology. Clarifying this association could support earlier identification of patients at risk for exercise limitation and guide monitoring strategies using CMR fibrosis measures.

Probable Antiphospholipid Syndrome Causing Biventricular Thrombi and Cardiogenic Shock.

This JACC Case Reports article describes a 70-year-old woman with recent Takotsubo cardiomyopathy who presented with cardiogenic shock and was found to have biventricular intracardiac thrombi. Initial laboratory testing suggested probable antiphospholipid syndrome (APS), and management included inotropic support and anticoagulation, but attempts to wean inotropes failed and the patient chose hospice care. The case underscores the diagnostic uncertainty and limited evidence for treating extensive intracardiac thrombosis in suspected APS, especially when complicated by Takotsubo physiology.

Dilated Cardiomyopathy in a Woman With SPG4-Associated Hereditary Spastic Paraplegia.

This case report studied a 54-year-old woman with genetically confirmed SPG4-associated hereditary spastic paraplegia (SPG4-HSP) who developed progressive dyspnea and a new left bundle branch block. Echocardiography and cardiac magnetic resonance (CMR) showed nonischemic dilated cardiomyopathy (DCM) with reduced ejection fraction and dyssynchrony, with alternative causes excluded and extended cardiomyopathy gene testing negative. The report is clinically significant because it documents DCM as a previously unreported systemic cardiac manifestation of SPG4-HSP and highlights the need to consider cardiomyopathy in SPG4-HSP patients.

Apical Takotsubo Syndrome After Elective Stenting of the Left Anterior Descending Artery.

This case report studied a 77-year-old woman with stable coronary artery disease who developed apical takotsubo syndrome shortly after elective percutaneous coronary intervention with left anterior descending (LAD) artery stenting. Despite postprocedural chest pain and electrocardiographic changes mimicking acute myocardial infarction, coronary angiography showed a patent stent without acute thrombosis. The finding is significant because it emphasizes that takotsubo syndrome can occur after PCI and may be misclassified as procedural type 4a MI, affecting diagnostic and management decisions.

Microaxial Left Ventricular Assist Device as Bridge to Transplantation in Postinfarction Left Ventricular Pseudoaneurysm.

This case report studied a 61-year-old man with postinfarction left ventricular (LV) pseudoaneurysm presenting with recurrent cardiogenic shock one month after myocardial infarction. Transthoracic echocardiography and CMR identified a large apical LV pseudoaneurysm compressing the right ventricle, and because surgical risk was prohibitive he was supported with prolonged Impella 5.5 therapy as a bridge to heart transplantation. The report is scientifically and clinically significant because it demonstrates feasibility of Impella 5.5–based mechanical support to stabilize a high-risk LV pseudoaneurysm patient until transplant.

The timing and relationship of ventricular arrhythmia with exercise patterns in veteran male endurance athletes.

This study examined whether exercise training patterns were associated with the incidence and timing of ventricular arrhythmias in 106 healthy veteran male endurance athletes (cyclists/triathletes, age ≥50) using cardiac magnetic resonance (CMR) and implantable loop recorders (ILRs). Over follow-up, 55 ventricular arrhythmia events occurred and the investigators assessed temporal relationships between arrhythmia occurrence and exercise patterns tracked by computerized devices. The significance lies in identifying how long-term endurance training may influence ventricular arrhythmia timing, informing risk stratification and monitoring strategies in veteran athletes.

Myocardial fibrosis and its relationship with ventricular arrhythmias and reduced ventricular systolic function in young and veteran endurance athletes.

This study evaluated myocardial fibrosis and its relationship to ventricular arrhythmias and reduced ventricular systolic function in 296 young (median age 19), 138 middle-aged endurance athletes, and 66 middle-aged non-athletic controls without known cardiac disease. Using CMR to quantify myocardial fibrosis and biventricular function and 24-hour Holter monitoring to quantify ventricular arrhythmias, the authors found non-hinge-point fibrosis was more prevalent in middle-aged athletes than in young athletes and controls. The findings are significant because they link age- and training-associated myocardial fibrosis to arrhythmia burden and systolic function changes, refining the concept of athlete’s heart remodeling.

Cardiopulmonary physical fitness and tissue characterization through T1 and T2 mapping: new insights on athlete’s heart.

This study investigated associations between cardiopulmonary fitness and cardiac remodeling measured by CMR T1 and T2 mapping in elite healthy athletes undergoing maximal cardiopulmonary exercise testing (CPET) and non-contrast CMR. The key finding was that CMR-derived T1/T2 tissue characterization metrics were related to measures of physical fitness from CPET, providing new insights into how vigorous exercise affects myocardial properties. The significance is that T1/T2 mapping may help distinguish physiologic athlete’s heart adaptations from early cardiomyopathic processes when interpreting CMR in athletes.

Exercise recommendations for patients with Marfan syndrome: an updated review.

This updated review studied evidence and clinical guidance on exercise recommendations for patients with Marfan syndrome (MFS), a genetic autosomal dominant connective tissue disorder with major cardiovascular risks such as aortic root dilatation and dissection. The key conclusion was that exercise is beneficial in general but requires tailored restrictions in MFS due to the condition’s unique cardiovascular pathology and exercise-related hemodynamic stress. The significance is that it provides updated, clinically actionable recommendations to balance cardiovascular benefits against the heightened risk of aortic complications in MFS.

Cardiac magnetic resonance feature tracking in Olympic athletes: a myocardial deformation analysis.

This study examined myocardial deformation in Olympic athletes using cardiac magnetic resonance (CMR) feature tracking to characterize athlete’s heart and differentiate it from early cardiomyopathy. In Olympic athletes with normal cardiovascular evaluation compared with age- and sex-matched sedentary controls, the authors assessed CMR cine-derived deformation patterns and evaluated differences by sports discipline and sex. The significance is that CMR feature tracking may improve interpretation of myocardial mechanics in athletes, supporting more accurate differential diagnosis when screening for cardiomyopathies.

Integrating cardiac CT into the diagnostic pathway of Takotsubo syndrome: current evidence and future directions.

This review studied how integrating cardiac computed tomography (cardiac CT) into the diagnostic pathway for takotsubo syndrome (TS) compares with the current reference standard of cardiac magnetic resonance (CMR). The key finding was that while CMR provides detailed ventricular function and tissue characterization, cardiac CT can be valuable when CMR is contraindicated or limited (e.g., device incompatibility, claustrophobia, arrhythmia), and the review outlines evidence and future directions for CT’s role. The significance is that it supports broader, practical imaging algorithms for suspected TS to reduce diagnostic delays and improve differentiation from acute coronary syndrome.

CardioMorphNet: Cardiac motion prediction using a shape-guided Bayesian recurrent deep network.

This paper studied CardioMorphNet, a shape-guided Bayesian recurrent deep learning model for predicting 3D cardiac motion from short-axis (SAX) cine CMR images. The key technical finding is that the network uses a recurrent variational autoencoder to model spatiotemporal dependencies across the cardiac cycle and incorporates posterior models for bi-ventricular segmentation and deformable registration, addressing limitations of intensity-based registration losses. The significance is that improved cardiac motion estimation from CMR could enhance quantitative assessment of cardiac function and detection of abnormalities in clinical imaging workflows.

Cardiovascular Manifestations of Systemic Lupus Erythematosus: A Practical Multi-Modality Imaging Approach.

This review studied cardiovascular manifestations of systemic lupus erythematosus (SLE) and how to detect, characterize, and monitor them using multimodality cardiovascular imaging in SLE patients. It found that echocardiography, cardiac magnetic resonance (CMR), computed tomography (CT), and nuclear imaging each provide complementary strengths for pericardial disease, myocarditis, coronary artery disease, and valvular involvement, with important modality-specific limitations. The clinical significance is that an imaging strategy tailored to the suspected SLE cardiac phenotype can improve diagnosis and longitudinal risk assessment while avoiding overreliance on any single technique.

Concomitant pericardiectomy and coronary artery bypass grafting associated with marked reduction in liver stiffness in a patient with constrictive pericarditis: a case report.

This case report studied a patient with constrictive pericarditis who underwent concomitant pericardiectomy and coronary artery bypass grafting, focusing on systemic effects reflected by liver stiffness. The key finding was a marked reduction in liver stiffness after surgical relief of constrictive physiology despite the complexity of concomitant three-vessel coronary disease and liver dysfunction. This is clinically significant because it provides rare in vivo evidence that pericardiectomy can reverse congestive hepatopathy/fibrosis-related stiffness in constrictive pericarditis.

Left Ventricular Global Longitudinal Strain Improves Risk Stratification in Chronic Aortic Regurgitation.

This retrospective cohort study evaluated whether cardiac magnetic resonance (CMR) feature tracking-derived left ventricular global longitudinal strain (FT-LVGLS) predicts adverse outcomes in patients with chronic moderate-to-severe aortic regurgitation (AR), including 385 minimally symptomatic patients (NYHA I–II) undergoing CMR from 2010–2024. The key finding was that FT-LVGLS improved risk stratification for adverse outcomes and provided incremental prognostic value beyond the 2025 ESC/EACTS Class I/IIb surgical indication parameters. Clinically, this suggests FT-LVGLS can refine timing of intervention decisions in chronic AR by improving individualized outcome prediction.

In vivo evidence of blood flow slippage: failure of the no-slip boundary condition assumption.

This study investigated whether the in vivo “no-slip” boundary condition holds for blood flow by measuring near-wall tangential velocities and wall shear stress in seven healthy adult volunteers using 4D-flow cardiovascular magnetic resonance (4D-flow CMR) and Navier–Stokes modeling with data assimilation. The key finding was evidence of blood flow slippage, with near-wall tangential velocities on the order of ~30 (units truncated in abstract) indicating failure of strict zero-velocity no-slip behavior in vivo. This is scientifically significant because it challenges a foundational assumption in cardiovascular fluid dynamics models used to compute hemodynamic forces.

A Slc5a6-Deficient Mouse Model Reveals Metabolically Driven Cardiomyopathy with Therapeutic Potential for Vitamin-Based Intervention.

This preclinical study examined how loss of the sodium-dependent multivitamin transporter encoded by SLC5A6 causes cardiomyopathy by analyzing two human families with SLC5A6 mutations and generating a cardiac-specific SLC5A6 knockout mouse model (Slc5a6cKO). The key finding was that Slc5a6cKO mice developed progressive metabolically driven dilated cardiomyopathy with impaired coenzyme A synthesis and that vitamin supplementation had therapeutic potential. The clinical significance is that SLC5A6-related biotin/pantothenic acid deficiency may be a treatable metabolic mechanism underlying early-onset dilated cardiomyopathy.

The Effect of Aortic Regurgitation on Left Ventricular Flow Dynamics Assessed by 4D-Flow MRI.

This study assessed how aortic regurgitation (AR) alters left ventricular (LV) flow dynamics using four-dimensional flow MRI (4D-flow MRI), with severity contextualized by regurgitant fraction (RF) and additional hemodynamic burden captured by viscous energy dissipation (VED). The key finding (from the study’s aim and framing) is that 4D-flow MRI–derived flow metrics and VED can characterize diastolic filling and quantify the hemodynamic impact of AR beyond conventional measures. Scientifically and clinically, this supports using 4D-flow MRI to better phenotype AR severity and its LV consequences.

Open-Irrigated Helical Radiofrequency Septal Ablation for Obstructive Hypertrophic Cardiomyopathy.

This JACC Case Reports article studied a 60-year-old man with drug-refractory obstructive hypertrophic cardiomyopathy (oHCM) undergoing open-irradiated helical radiofrequency septal ablation using a novel dedicated open-irrigated helical radiofrequency catheter via subclavian venous access. The key finding was an immediate reduction in provoked LV outflow tract gradient from 130 to 30 mm Hg with sustained improvement at 12 months, septal fibrosis on 6-month cardiac magnetic resonance, and no procedural or follow-up complications. Clinically, it suggests this specific catheter-based technique may be a feasible septal reduction therapy option for oHCM when medical therapy fails.

CA in AF With LVSD With and Without LV Fibrosis: Results From the CAMERA-MRI II Trial.

This analysis of the CAMERA-MRI II randomized trial studied catheter ablation (CA) versus medical rate control in atrial fibrillation (AF) with left ventricular systolic dysfunction (LVSD), stratifying outcomes by cardiac magnetic resonance (CMR) late gadolinium enhancement (LGE) burden (LV LGE ≥5% vs <5%). The key finding was that LV fibrosis status defined by LGE can differentiate CA outcomes in AF patients with LVSD, addressing whether fibrosis modifies treatment benefit. Clinically, this supports using CMR LGE to risk-stratify AF-LVSD patients when considering CA.

Machine Learning-based Model for Major Adverse Cardiac Event Prediction in Patients with Hypertrophic Cardiomyopathy.

This retrospective cohort study developed a machine learning model to predict major adverse cardiac events (MACEs) in patients with hypertrophic cardiomyopathy (HCM) using cardiac MRI features (balanced cine SSFP, native T1/T2 mapping, and late gadolinium enhancement) from September 2015 to December 2022. The key finding was that a penalized Cox proportional hazards approach with elastic net regularization (CoxNet) identified high-risk HCM patients and quantified key imaging predictors of MACE risk. Scientifically and clinically, the model could improve risk stratification for cardiovascular death, resuscitated sudden cardiac death, and heart failure hospitalization in HCM using routinely acquired CMR data.

AI-based Histologic Heterogeneity of Microvascular Obstruction at Cardiac MRI for Predicting MACEs: A Multicenter Study.

This multicenter retrospective study evaluated an AI-based framework that combined automated microvascular obstruction (MVO) segmentation with radiomic feature extraction to predict MACEs in STEMI patients with MVO undergoing cardiac MRI. The key finding was that AI-derived heterogeneity metrics of microvascular injury improved prediction of major adverse cardiovascular events compared with approaches relying on manual or less informative quantification. This is significant because it enables scalable, more nuanced characterization of microvascular damage that may refine post-STEMI prognosis.

Association of Mitral Annular Disjunction on Magnetic Resonance Imaging With Cardiovascular Outcomes.

This prospective CMR registry analysis studied the prevalence and prognostic impact of mitral annular disjunction (MAD) on cardiac magnetic resonance (CMR) and its association with native T1 relaxation times measured in end-systole and end-diastole in 1969 patients. The key finding was that MAD assessed by CMR was associated with cardiovascular outcomes and showed relationships with native T1 relaxation, suggesting underlying myocardial tissue alterations. Clinically, CMR-based MAD assessment may help identify patients at higher risk and provide mechanistic linkage to myocardial remodeling via T1 changes.

Biventricular dysfunction and blood oxygenation deficits in obstructive sleep apnea: a prospective study with non-contrast cardiac MRI.

This prospective study examined whether non-contrast cardiac MRI measures of biventricular function, mechanics, and tissue characteristics differ between severe and non-severe obstructive sleep apnea (OSA) and how they relate to nocturnal hypoxemia in 75 newly diagnosed OSA patients. The key finding was that severe OSA showed measurable abnormalities on non-contrast CMR (including native T1 and T2 mapping) consistent with subclinical myocardial injury and that these imaging findings correlated with markers of nocturnal hypoxemia. Scientifically, it supports using non-contrast CMR for earlier detection of cardiac involvement in OSA when conventional metrics may appear normal.

This case report studied management constraints in cardiogenic shock due to arterial tortuosity syndrome (ATS) presenting with arterial hypoplasia in a 19-year-old man. The key finding was that extreme iliofemoral and aortic hypoplasia and tortuosity (e.g., 3 mm iliofemoral arteries and 19 mm ascending aorta) made mechanical thrombectomy and peripheral VA-ECMO technically unfeasible despite multimodality imaging (cranial CTA, aortic angiography, and cardiac MRI). Clinically, it highlights the need for early vascular feasibility assessment and alternative mechanical support strategies in ATS patients.

CMR-derived left ventricular pressure-volume loops enhance individualized assessment of disease severity and prognosis in pulmonary arterial hypertension in adults.

This study investigated whether cardiovascular magnetic resonance (CMR)-derived left ventricular pressure–volume (PV) loops improve individualized assessment of disease severity and prognosis in adults with pulmonary arterial hypertension (PAH). The key finding was that CMR-based LV PV-loop metrics were associated with outcomes (time to death or lung transplantation) and provided prognostic information alongside clinical and hemodynamic data obtained from right heart catheterization and blood pressure. Scientifically, it supports PV-loop–based CMR as a noninvasive tool to better characterize LV underfilling and risk in PAH.

Synergistic enhancement mechanism of biochar from Chinese medicine residue for tetracycline hydrochloride removal.

This environmental engineering study investigated converting Chinese medicine residue into biochar using hydrothermal and KOH pretreatment followed by high-temperature pyrolysis to enhance tetracycline hydrochloride (T-HCl) removal. The key finding was that the combined hydrothermal + KOH treatment produced KHRB with a highly developed pore structure (specific surface area 1589 ± 24.62 m2/g) and substantially improved adsorption performance for T-HCl. Scientifically and practically, it demonstrates a synergistic waste-to-resource approach for improving antibiotic removal efficiency using engineered biochar.

Dual-Phase 3D Modified Dixon Steady-State MR Angiography in Pediatric Complex Congenital Heart Disease.

This retrospective single-center study evaluated dual-phase 3D modified Dixon (mDixon) steady-state MR angiography (MRA) in pediatric patients with complex congenital heart disease undergoing 3T cardiac MRI with respiratory navigator gating and interleaved systolic/diastolic acquisition. Dual-phase imaging improved phase-dependent vessel border delineation and enabled more reliable vessel diameter measurements compared with single-phase performance (as assessed by two independent readers). The technique’s ability to capture cyclic/phase-related vascular detail without breath-holding may improve noninvasive pediatric CHD vascular assessment and measurement consistency for clinical planning and follow-up.

Arteriovenous fistula creation results in cardiac dysfunction and remodeling in a uremic pig model.

This preclinical study used a uremic pig model of chronic kidney disease induced by renal embolization to test whether arteriovenous fistula (AVF) creation, supported by percutaneous transluminal angioplasty (PTA), causes cardiovascular dysfunction and remodeling. AVF creation produced adverse cardiac remodeling and impaired cardiac function in the uremic setting, linking AVF-related hemodynamic compensation to downstream heart injury. These findings support the uremic large-animal model as a mechanistic platform to study why AVF contributes to cardiovascular morbidity in end-stage kidney disease and to test potential interventions.

Multi-organ infarctions secondary to a cardiac papillary fibroelastoma in early childhood.

This report described a 4-year-old girl with acute stroke and renal infarction in whom transthoracic echocardiography identified a cardiac mass and cardiac MRI confirmed a cardiac papillary fibroelastoma (CPFE). Surgical resection established the diagnosis on histopathology, highlighting CPFE as the embolic source despite its rarity in early childhood. Clinically, the case emphasizes that CPFE should be included in the differential diagnosis of pediatric embolic events when a cardiac mass is present.

Ferumoxytol-Enhanced Myocardial T1 Tracking Using a Hybrid 2D/3D Steady-State MRI Sequence Captures Cyclic Intramyocardial Blood Volume Dynamics.

This feasibility study developed a hybrid 2D/3D steady-state “T1 tracking” MRI technique to measure ferumoxytol-enhanced cyclic intramyocardial blood volume (iMBV) dynamics from systole to diastole on clinical MRI scanners. Ferumoxytol-enhanced T1 tracking captured systolic-to-diastolic iMBV changes, supporting detection of coronary microcirculation-related dynamics without vasodilator stress. If validated clinically, this approach could provide a noninvasive MRI biomarker for coronary artery disease and microvascular dysfunction using a single contrast-enhanced acquisition.

A rapid phage-free platform for antigen-specific VNAR screening with BATCH system.

This study created a phage-free bacterial two-hybrid screening platform (BATCH) for rapid antigen-specific VNAR discovery using a Cre recombinase-immunized Chiloscyllium plagiosum spleen cDNA library (~10^8 diversity). Using BATCH in BTH101 cells with dual lacZ and chloramphenicol resistance (CmR) readouts (enhanced by triple lacO sites and cAMP feedback), the authors identified two unique VNAR binders (VNAR1a and VNAR1b) against the target antigen. The method provides a faster, phage-independent alternative to phage display for generating single-domain shark antibody candidates with potentially improved access to cryptic epitopes.

From healthy to heart failure in 24 hours: defining the upper limit of exercise-induced cardiac fatigue.

This single-subject study investigated cardiac consequences of extreme exercise by performing serial echocardiography, rest and exercise cardiac MRI (CMR), and biomarker testing (BNP and cardiac troponin-I) before and after 12-hour and 24-hour intense cycling world-record attempts in a former professional ultra-endurance athlete. After the 12-hour attempt, the athlete showed no respiratory compromise and underwent detailed imaging/biomarker assessment to define the upper limit of exercise-induced cardiac fatigue, with further evaluation after the 24-hour attempt. The results aim to delineate how far extreme endurance exercise can be pushed before measurable cardiac injury or dysfunction occurs, informing safety thresholds for high-intensity training.

Prediction of Anthracycline-induced Cardiotoxicity Using Cardiac MRI Parameters: An Animal Study.

This animal study evaluated whether cardiac MRI native T1 and extracellular volume fraction (ECV) can predict early mortality from anthracycline-induced cardiotoxicity in 31 Sprague-Dawley rats treated with weekly intravenous doxorubicin (2 mg/kg) for up to 12 weeks. Using Cox proportional hazards modeling with time-dependent covariates, the authors assessed associations between MRI parametric mapping measures and early death, with histology performed after death to corroborate injury. If translatable, these MRI biomarkers could enable earlier identification of high-risk patients developing doxorubicin cardiotoxicity and guide timely cardioprotective management.

The role of advanced imaging in the diagnosis and management of scimitar syndrome in pediatric patients.

This imaging review studied the diagnostic and management role of advanced cardiac imaging (cardiac CT and cardiovascular magnetic resonance, CMR) in pediatric patients with scimitar syndrome (partial/total right anomalous pulmonary venous drainage). It found that CT/CMR delineate scimitar syndrome variants—right lung and pulmonary artery hypoplasia, abdominal aortopulmonary collaterals, and associated cardiac/bronchial anomalies—thereby linking anatomic findings to clinical presentation and surgical or rerouting strategies. The clinical significance is that CT/CMR characterization can guide individualized treatment planning and improve diagnostic confidence in this rare congenital cardiopulmonary disorder.

Absolute and workload-indexed exercise blood pressure responses: associations with cardiac output, vascular resistance, and cardiorespiratory fitness in females.

This study examined exercise systolic blood pressure (SBP) responses in 135 adult females (51±8 years) undergoing cardiopulmonary exercise testing across a wide fitness range, relating SBP patterns to cardiac output (CO), vascular resistance, and V̇o2peak. It found that SBP responses stratified by SBPmax (<190 vs ≥190 mmHg) and workload-indexed SBP (SBP/W-slope) were associated with the pressure–flow relationship (SBP relative to CO) and with cardiorespiratory fitness (V̇o2peak). The scientific significance is that workload-indexed SBP metrics may improve hemodynamic interpretation and risk/fitness assessment beyond absolute SBP during exercise.

The Rapid Long-axis Strain-based Prognostic Models Evaluate Composite Adverse Events for Asymptomatic Dextro-Transposition of the Great Arteries Patients after the Switch Operation.

This study assessed whether biventricular strain and rapid long-axis strain (RLAS) can detect impaired myocardial mechanics and predict composite adverse events in asymptomatic dextro-transposition of the great arteries (d-TGA) patients after arterial switch operation (ASO), using cardiovascular magnetic resonance (CMR) strain measurements. The key finding was that rapid long-axis strain–based prognostic models improved identification of patients at risk for composite adverse events compared with less informative strain metrics. Clinically, this supports earlier and more accurate long-term risk stratification in post-ASO d-TGA patients using CMR-derived strain.

Real-world multi-institution analysis of tarlatamab in patients with small cell lung cancer.

This real-world, multi-institution retrospective cohort analyzed tarlatamab outcomes in small cell lung cancer (SCLC) patients who received at least one dose between 5/16/2024 and 6/15/2025, with particular focus on a “trial-ineligible” population defined by factors such as ECOG performance status ≥2 and prior grade ≥2 pneumonitis/interstitial lung disease. The key finding was that real-world outcomes differed from those expected in pivotal trials because trial-ineligible patients were more likely to have baseline characteristics that could affect tolerability and effectiveness. This is clinically significant because it informs how tarlatamab performs in broader practice populations that would not have met clinical-trial eligibility criteria.

Atrial function and diastolic dysfunction using CMR

CMR-Derived Left Atrial Parameters for Assessing Diastolic Dysfunction and Prognosis in Hypertrophic Cardiomyopathy.

This dual-center study assessed whether CMR-derived left atrial (LA) parameters can diagnose guideline-defined left ventricular diastolic dysfunction (LVDD) and predict prognosis in 248 hypertrophic cardiomyopathy (HCM) patients versus 70 controls. Patients with elevated left atrial pressure (LAP; echocardiographic Grade ≥ II LVDD) showed distinct CMR LA volumetric/hemodynamic parameter patterns, and these CMR measures provided diagnostic and prognostic value for elevated LAP–defined LVDD. The findings suggest CMR LA metrics could improve risk stratification of diastolic dysfunction in HCM beyond echocardiography alone.

Heart failure and metabolic/nutritional reprogramming (preclinical)

A high-fat diet nutritional intervention reprograms cardiac metabolism and improves systolic function in a pig model of heart failure with reduced ejection fraction.

This randomized pig model study induced heart failure with reduced ejection fraction (HFrEF) with a metabolic switch toward increased myocardial glucose uptake by creating viable dysfunctional myocardium via progressive coronary artery stenosis, then tested whether a high-fat diet (20% lard) reprograms cardiac metabolism and improves systolic function. Compared with control diet, the high-fat diet improved systolic function and shifted cardiac metabolism away from the glucose-dominant state toward fatty-acid utilization. These preclinical results support nutritional/metabolic reprogramming as a potential therapeutic strategy for HFrEF.

Inflammation, immune-mediated cardiovascular injury, and myocarditis

Deciphering Leukocyte Subpopulation Contributions to Ventricle Remodeling and Neuroinflammation After Myocardial Infarction Using Total-Body Molecular Imaging.

Using a C57BL/6N mouse model of permanent coronary artery ligation to induce myocardial infarction (MI), this study used total-body molecular imaging with PET to determine how macrophages and neutrophils contribute to ventricle remodeling and concurrent neuroinflammation. Peripheral macrophage depletion with clodronate-loaded liposomes and neutrophil inhibition with a neutralizing anti-Ly6G antibody altered post-MI inflammatory signaling and neuroinflammatory responses, linking specific leukocyte subpopulations to downstream remodeling and risk. These mechanistic findings support targeting distinct immune cell populations to reduce both cardiac and neuroinflammatory consequences after MI.

Cardio-oncology and cancer therapy–related cardiovascular toxicity

Three-Hour Infusion of Methotrexate at 3 g/m2 With or Without Intrathecal Chemotherapy Significantly Reduces CNS Relapses and Improves Survival in Patients With Large B-Cell Lymphomas at Increased CNS Risk.

This prospective clinical study evaluated a pharmacokinetic-informed, CNS-directed high-dose methotrexate (HD-MTX) regimen—3 g/m2 infused over 3 hours with or without intrathecal chemotherapy—in 336 patients with large B-cell lymphomas (LBCL) at increased CNS risk who achieved complete metabolic response on CMR after RCHOP or derivatives. The protocol significantly reduced CNS relapses and improved survival compared with historical expectations for similar high-risk groups, with CNS risk reassessed using updated CNS-IPI and extranodal criteria. These results support a dosing-schedule–optimized HD-MTX strategy as an effective approach to prevent CNS recurrence in high-risk LBCL.

Transplantation and immunosuppression strategies

CTLA4-Ig + Anti-IL-6/IL-6R Treatment Results in Long-term Allograft Survival and Function in Highly HLA-sensitized Patients.

The study evaluated whether combining CTLA4-Ig with anti–IL-6/IL-6R therapy improves outcomes in highly HLA-sensitized (HS) transplant recipients at risk for cell-mediated rejection (CMR) and antibody-mediated rejection (AMR). The combined regimen was associated with long-term allograft survival and preserved graft function without the expected donor-specific antibody (DSA) rebound concerns when converting away from calcineurin inhibitor (CNI)–based regimens. This supports a CNI-free conversion strategy using CTLA4-Ig plus IL-6/IL-6R blockade as a clinically relevant option for HS patients with CNI neuro/nephrotoxicity.

Case reports of rare cardiac conditions and procedural complications

An indolent course of undifferentiated pleomorphic cardiac sarcoma mimicking myxoma: A case report.

This case report described a 71-year-old woman with cardiac undifferentiated pleomorphic sarcoma (UPS) that initially mimicked a myxoma, with early cardiac MRI showing only subtle atrial septal thickening. Over 2 years, follow-up imaging demonstrated progressive growth leading to surgical resection, and histopathology with immunohistochemistry confirmed high-grade UPS. The report emphasizes the diagnostic challenge of rare malignant cardiac tumors and the value of longitudinal imaging when initial findings are nonspecific.
