Repair of a ruptured posterior left ventricular pseudoaneurysm.

A 51 year old man with a large ruptured posterior left ventricular (LV) pseudoaneurysm (PsAn) was successfully surgically treated. Complete repair was performed by excision of the PsAn, leaving a cuff of fibrous tissue suitable to hold sutures and a Dacron patch reconstruction of the LV. On the 7 t h postoperative day, echocardiographic examination confirmed pericardial effusion (swinging heart). Mediastinal drainage tube was performed and the patient was discharged with a good recovery. The patient's preoperative LV ejection fraction (EF) increased from 42.7 to 52% after operation. We consider endoventricular circular patch plasty of ruptured posterior LV PsAn excellent because of the avoidance of thrombus and the effectiveness for improvement of LV function.
