- Abstract: A 67-year-old male was referred to our department for surgical treatment of a left ventricular mass after myocardial infarction. The left ventricular aneurysm was 50×20 mm and the papillary muscles were close to each other. To avoid displacement of the papillary muscles and its effect on the mitral valve, a double-patch closure was performed. A bovine pericardial patch was placed on the endocardial side and a Dacron patch on the epicardial side, and fibrin glue was injected between the two patches. Mitral valvuloplasty and coronary artery bypass grafting were also performed, and the patient had an uncomplicated postoperative course and was discharged home on the 27th postoperative day. Histopathological findings showed no myocardial cells in the wall of the mass, and a diagnosis of pseudoaneurysm was made. Double-patch closure is considered effective for left ventricular masses with a large opening and close proximity to the papillary muscle, as in this case.
