[Ventricular pseudo-false aneurysm after myocardial infarction; report of a case].

A 72-year-old man was admitted to our hospital with chest discomfort and syncope. The echocardiography showed the left ventricular aneurysm. The coronary arteriography revealed a complete occlusion at distal portion of the right coronary artery and anterior aneurysm of the left ventricle was demonstrated. We diagnosed that it was false aneurysm because of communicating with the left ventricle through a small orifice. Surgical repair was carried out after resection of the aneurysm of the left ventricle. The postoperative course was uneventful and discharged on the 33rd day after surgery. Pseudo-false ventricular aneurysm of the left ventricle was diagnosed by histological examination.
