Double-trouble Doppler: reduction in aortic flow due to combined left ventricular outflow tract obstruction and severe aortic stenosis, complete diagnosis by transthoracic Doppler echocardiography.
In patients with hypertrophic obstructive cardiomyopathy and dynamic left ventricular outflow tract obstructions, an additional fixed obstruction may uncommonly coexist. In these situations, flow through the aortic valve is usually delayed but typically still throughout the entire ejection period. We describe a case of marked reduction in aortic flow during mid and late systole, diagnosed by Doppler echocardiography, caused by combined hypertrophic obstructive cardiomyopathy and severe calcific bicuspid aortic stenosis.
