Paradoxical systolic and diastolic flow abnormalities in hypertrophic cardiomyopathy with mid-cavity systolic obstruction
Cardiol J 2011;18(3):314-317.
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. (Cardiol J 2011;
