title: Posterior mitral abscess with bypass grafting before annulus reconstruction: a case report.
abstract: A posterior mitral annular abscess is a rare but severe complication of endocarditis which requires careful surgical intervention. The debridement and reconstruction can cause fatal complications such as left atrioventricular groove rupture, coronary artery entrapment, and acute myocardial infarction. We report on a 60-year-old woman who developed acute infective endocarditis of her native mitral valve complicated by a posterior annular abscess, and who underwent precautionary bypass grafting to a dominant circumflex coronary artery before extensive atrioventricular groove debridement and reconstruction.
