Idiopathic hypertrophic subaortic stenosis and coronary atherosclerosis. Results of coronary artery bypass alone and myectomy combined with coronary artery bypass
CC Gill, AM Duda, H Kitazume, JR Kramer and FD Loop
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.
