[A case of surgically treated hypertrophic obstructive cardiomyopathy suffering from angina pectoris during hemodialysis].
Surgical procedure for hypertrophic obstructive cardiomyopathy (HOCM) in a patient chronic hemodialysis has not been reported in Japan. This is a case report of a 61-year-old male who had been suffering from angina pectoris during hemodialysis. Cardiac catheterization showed a systolic pressure gradient of 79 mmHg at the left ventricular outflow tract and left ventriculogram demonstrated severe mitral regurgitation. He underwent mitral valve replacement and left ventricular myectomy with hemodialysis and extracorporeal ultrafiltration method during cardiopulmonary bypass. Postoperative catheterization showed a decrease of pressure gradient to 19 mmHg at the left ventricular outflow tract, and relief of angina was obtained.
