Quantification of exercised-induced myocardial deformation with exercise CMR

Manuel A. Morales, Fahime Ghanbari, Jennifer Rodriguez, Deepa M. Gopal et autres

BACKGROUND: Physiological stress may reveal myocardial deformations not evident at rest. Single-beat myocardial tagging in exercise cardiovascular magnetic resonance (Ex-CMR) enables assessment of myocardial deformation at both rest and during exercise. In this study, we developed the myocardial torsional reserve (MTR), a …

Abstract 4370414: Radiomics-Based Coronary Heart Disease Classification Using Cine Cardiac MRI in a Bi-Racial Cohort

Radhika Deshpande, Yi Meng, Kevin S. Peters, Ahmed Fahmy et autres

Introduction: Coronary heart disease (CHD) remains a leading global health burden. Cine cardiovascular magnetic resonance (CMR), the gold standard for evaluating left ventricular (LV) structure and function, avoids contrast but relies on human-derived clinical measures. Radiomics, a high-throughput image analysis method, offers …

Abstract 4371213: Integrated Radiogenomics Improves Classification of Genetic Hypertrophic Cardiomyopathy

Ujwala Shenoy, Marcela Cuellar-Lobo, Lu Zhang, Radhika Deshpande et autres

Background: The prognosis of hypertrophic cardiomyopathy (HCM) varies by several factors, including imaging characteristics and genotype, reflecting underlying pathology. Traditional machine learning models typically require large datasets, which are challenging to obtain in rare disease research. Bayesian Networks (BN) excel with limited …

Abstract 4368727: Characteristics and Prognosis of Non-Dilated Idiopathic Non-Ischemic Cardiomyopathy: A Distinct Clinical and Prognostic Entity

Marcela Cuellar-Lobo, Chidiogo Orizu, Elizabeth Király, Victoria Bothwick et autres

Backround: Idiopathic non-ischemic cardiomyopathy (iNICM) includes patients without identifiable causes of left ventricular systolic dysfunction. While dilated cardiomyopathy (DCM) has been extensively studied, the entity of non-dilated iNICM remains poorly understood. Methods: We retrospectively identified 197 consecutive patients with AHA/ACC Stage B …

Age- and sex-differences and reference values for ventricular strain by cardiovascular magnetic resonance imaging in adults without cardiovascular disease or cardiovascular disease risk factors

Rohit Pillai, Lu Zhang, Kevin S. Peters, Vibhav Jha et autres

BACKGROUND: Myocardial deformation measured by myocardial strain is an important marker of cardiovascular disease (CVD). We aimed to establish normal values and examine age- and sex-differences in left and right ventricular (LV, RV) strain using feature tracking cardiovascular resonance (FT-CMR) in adults …
