Association of Left Ventricular Outflow Tract Obstruction with Left Atrial Remodeling and Dysfunction in Hypertrophic Cardiomyopathy: A Three‐Dimensional Echocardiography and Left Atrial Strain Study

Abstract

To compare left atrial (LA) structure and phasic function among healthy controls and patients with nonobstructive or obstructive hypertrophic cardiomyopathy (HCM), and assess their associations with left ventricular outflow tract obstruction (LVOTO).
