title: [Idiopathic hypertrophic subaortic stenosis in aortic valve disease-diagnosis using echocardiography].
abstract: In three patients with valvular aortic disease in addition isiopathic hypertrophic subaortic stenosis (IHSS) was proven by echocardiography. From the clinical standpoint the dynamic subvalvular stenosis was not supposed in all cases. IHSS was echocardiographically characterized by asymmetrical septum hypertrophy and systolic anterior movement of the anterior mitral leaflet. Isolated aortic valve insufficiency was found in two patients, and combined stenosis and insufficiency in one patient. Mitral leaflet fluttering - indicative of aortic valve insufficiency - was observed in two patients. The identification of the dynamic subvalvular stenosis in patients with valvular aortic disease is important for the therapeutical approach. Echocardiography is very suitable for the diagnosis of this combined heart disease.
