[Infective endocarditis: a complication of idiopathic hypertrophic subaortic stenosis (author's transl)].

The idiopathic hypertrophic subaortic stenosis (IHSS) is thought to be infrequently complicated by infective endocarditis. Because IHSS is a disorder of the myocardium and not endocardium is not generally considered to have increased risk of infective endocarditis. Some Authors found, however, that approximately 5% of patients with IHSS develop bacterial endocarditis, because hemodynamically IHSS is like to valvular diseases.
