[Clinical diagnosis of idiopathic hypertrophic aortic subvalvular stenosis and an evaluation of the treatment methods].

Fifty-eight patients with idiopathic hypertrophic subaortic stenosis were examined in dynamics. In 25 of them routine general clinical methods of diagnosis were supplemented by echocardiography. In 34 patients the diagnosis was verified in examination by means of intracardiac methods. The authors demonstrated that idiopathic hypertrophic hypertrophic subaortic stenosis may be diagnosed by means of routine clinical methods of examination. Besides identifying the type of the valvular disease, echocardiography gives an idea of the function of the mitral valve. The first results of the management of patients with idiopathic hypertrophic subaortic stenosis are shown. The possibility of conservative treatment with agents blocking beta-adrenergic receptors is noted.
