We report here a case of pseudo-false aneurysm of the left ventricle with ventricular septal perforation following myocardial infarction. An 85-year-old man was treated for acute inferior myocardial infarction three months previously. He was admitted due to an acute posterior myocardial infarction. Since a cardiac catheter study showed three diseased coronary arteries, a left ventricular aneurysm and a ventricular septal perforation, he underwent emergency surgery. The ventricular aneurysm was located on the right side along the posterior descending branch, and was 4~1.5cm in size. We ruled out a false aneurysm because there was no adhesion between the epicardium and the pericardium. The communication between the aneurysm and the left ventricle was then closed with a Gore-Tex patch, and the perforation of the right ventricle was closed directly. CABG was performed for the left anterior descending artery using a vein graft. The postoperative course was uneventful, and he was discharged on the 27th post-operative day. The pathological findings showed a pseudo-false aneurysm of the ventricle.
