title: Idiopathic hypertrophic subaortic stenosis and coronary atherosclerosis. Results of coronary artery bypass alone and myectomy combined with coronary artery bypass.
abstract: Twenty-one patients with combined coronary artery disease and idiopathic hypertrophic subaortic stenosis (IHSS) have had coronary artery bypass grafting alone (Group I, n = 7) or in combination with left ventricular septal myectomy (Group II, n = 14). Patients ranged in age from 46 to 73 years (mean 59 years). There were no operative deaths, but one Group I patient died 16 months after operation. Patients in Group I have had continuing symptoms after the operation, whereas Group II patients have had consistent relief of symptoms. Patients with documented IHSS and coronary atherosclerosis should undergo combined coronary bypass and septal myectomy if symptoms recur with medical management.
