A 54-year-old man was admitted to
our hospital because of hypertrophic obstructive cardiomyopathy
(HOCM). Medical treatment was not effective. Cardiac catheterization
showed a peak systolic pressure gradient of 143mmHg between the
left ventricle and the ascending aorta. Echocardiogram showed
a systolic anterior motion and moderate mitral regurgitation
without asymmetric septal hypertrophy. He underwent mitral valve
replacement (MVR) with a 27-mm SJM instead of myectomy due to
his relatively thin ventricular septum of 16mm. Postoperative
cardiac catheterization revealed no significant pressure gradient
between the left ventricle and the ascending aorta. MVR is the
most effective surgical treatment of HOCM without asymmetric
septal hypertrophy.
