Key result
Echocardiography diagnosed combined hypertrophic and membranous subvalvular aortic stenosis by identifying severe asymmetric septal hypertrophy and a left ventricular outflow tract membrane.
Echocardiography can identify combined hypertrophic and membranous subvalvular aortic stenosis by revealing specific anatomical and functional abnormalities.
Echocardiography may detect combined subvalvular stenoses in select LVOT cases; leaves open prevalence, natural history, and management strategies.
Combined hypertrophic and membranous subvalvular aortic stenosis was detected by echocardiography. The diagnosis was established by the discovery of severe asymmetric septal hypertrophy, a membrane in the left ventricular outflow tract, narrowing of the left ventricular outflow tract, as well as high frequency fluttering and premature systolic closure of the aortic valve leaflets.
