Successful treatment of left ventricular patch infection by latissimus dorsi muscle flap covering without patch removal

Abstract

Removal of the infected prosthesis is considered an essential procedure in the treatment of prosthetic graft infection following cardiovascular surgery. Here, we present a case of left ventricular patch infection following repair of left ventricular rupture that was successfully treated by coverage with a latissimus dorsi muscle flap without patch removal. A 61-year-old man underwent double-patch repair for left ventricular-free wall rupture following posterior myocardial infarction. He underwent drainage and omental transposition with re-sternotomy for postoperative mediastinitis by Candida albicans, followed by pericardial fenestration via left thoracotomy for infectious pericarditis; however, left ventricular patch infection was detected. Considering the high invasiveness of a reoperation for patch removal, we preserved and covered the patch using a left pedicled latissimus dorsi muscle flap via left thoracotomy. The postoperative course was uneventful, and the patient was asymptomatic with no signs of recurrence at 30 months.
