Idiopathic hypertrophic subaortic stenosis picture
Idiopathic hypertrophic subaortic stenosis is a form of cardiomyopathy in which the
apex or septum of the heart is hypertrophied such that together with the anterior mitral
valve leaflet, an obstruction to blood flow during systole is formed. In some cases it is
an autosomal dominant trait with variable expression.
