Notes:

Idiopathic Hypertrophic Sub-aortic Stenosis (IHSS) is a hyperdynamic contractile state with near-cavity obliteration during systole. It is also characterized by dynamic motion of the anterior mitral leaflet toward the interventricular septum during systole. This dynamic narrowing of the left ventricular outflow tract produces a pressure gradient during systole detectible by Doppler. The m-mode shows the forward motion during systole. In some patients, the myocardial hypertrophy is more symmetric than the asymmetric arrangement which usually occurs in this disorder.
