Abstract

BACKGROUND: Hypertrophic cardiomyopathy (HCM) exhibits substantial phenotypic heterogeneity; however, differences in left atrial (LA) function among morphological subtypes remain poorly characterized. Cardiac magnetic resonance feature tracking (CMR-FT) offers advanced capabilities for quantifying LA deformation, yet its application to the evaluation of subtype-specific LA mechanics remains limite…
