Paradoxical systolic and diastolic flow abnormalities in hypertrophic cardiomyopathy with mid-cavity systolic obstruction

Abstract

Systolic obstruction of the left ventricular outflow tract, either at rest or during provocation, is a frequent finding in patients with hypertrophic cardiomyopathy. Mid-cavity obstruction is uncommon, and intraventricular diastolic pressure gradients in association with either mid-cavity of apical hypertrophy are reported only rarely. We describe a patient with hypertrophic cardiomyopathy with evidence of systolic mid-cavity obstruction, and with complex diastolic paradoxical flow abnormalities within the left ventricular cavity detected by colour and pulsed-wave Doppler. Contrast echocardiography confirmed the presence of diastolic and systolic obstruction at the mid-ventricular level, with evidence of an apical cavity sequestered from the main body of the left ventricle during systolic mid-cavity obliteration.
