Impact of Septal Reduction on Left Atrial Size and Diastole in Hypertrophic Cardiomyopathy

Both myectomy and alcohol septal ablation (ASA) can substantially reduce left ventricular (LV) outflow obstruction, relieve symptoms, and improve outcomes in hypertrophic cardiomyopathy (HCM). It is unclear whether septal reduction decreases left atrial (LA) size and improves diastolic function. The aim of this study was to analyze the consequences of septal reduction on LA size and diastolic function in a cohort of patients with HCM.Forty...
