Abstract:
We describe the case of a 73-year-old man with methicillin-resistant Staphyloccocus aureus (MRSA) endocarditis, which developed into a right ventricular pseudoaneurysm that fistulated into a previous saphenous vein graft to his distal right coronary artery (RCA). The patient was taken for a redo sternotomy, surgical evacuation of the abscess, bovine pericardial patch reconstruction of the right ventricular free wall, and tricuspid valve repair. Despite our best efforts and a repair that appeared sufficient at the time of operation, the patient died of ischemic colitis on postoperative day 5. This case report highlights some of the surgical considerations for such a rare and lethal condition.
