Abstract

Abstract A patient with severe, symptomatic hypertrophic cardiomyopathy (HCM) without a significant left ventricular outflow tract (LVOT) gradient at rest requires further evaluation. During exercise echocardiography (EE) performed on a supine bicycle, a latent or underestimated dynamic obstruction may be identified in real time, with postprandial assessment being particularly relevant.
