Abstract
The presence of an annular abscess complicates the operation for infective endocarditis. We report a case of a totally endoscopic repair of a mitral annular abscess using a staged strategy. A 28-year-old woman underwent endoscopic mitral valve repair for active infective endocarditis (AIE) with Staphylococcus aureus. At the index operation, the mitral annular abscess was completely debrided, yielding an annular defect. The mitral valve was repaired with the autologous pericardial patch and an annuloplasty. Primary repair of the annular defect was not performed because of the fragility of edematous tissues. Two weeks after index surgery, when the infection was under control, and the scar tissue had formed around the annulus, we performed the second stage operation involving repair of the annular abscess. The scar formation enabled annular reconstruction and additional repair of the mitral valve in a totally endoscopic fashion. The postoperative course was uneventful, and there was no recurrence at 5 months. An annular abscess may be repaired with staged surgery in select situations.
