抄録

Midventricular obstructive hypertrophic cardiomyopathy (MVOHCM) is a rare form of hypertrophic cardiomyopathy (HCM). An 80-year-old man was administered bisoprolol and warfarin therapies as treatment for MVOHCM with an apex aneurysm due to myocardial damage and intra-aneurysmal thrombus not complicated by atrial fibrillation. The pressure gradient in the midventricle successfully improved from 53.9 to 21.8 mmHg, and the intra-aneurysmal thrombus disappeared.
