title: Mitral valve replacement through right thoracotomy after coronary arterial bypass grafting with functioning conduits.
abstract: A 67-year-old man who had undergone coronary artery bypass grafting 3 years previously suffered from severe mitral regurgitation associated with Streptococcal infective endocarditis. He was placed in New York Heart Association functional class III. Preoperative angiography demonstrated good opacification of all 3 conduits implanted in the previous operation. We replaced the mitral valve through an anterolateral right thoracotomy, approaching the mitral valve as an alternative to redoing sternotomy to minimize potential injury to patent grafts. His postoperative course was uneventful. After a 1-month course of antibiotics, the patient was discharged as New York Heart Association class II and at present, 3 months after discharge, is doing well. This approach is an effective alternative to redoing sternotomy for mitral valve operation, especially in patients undergoing a previous coronary arterial bypass grafting via median sternotomy.
