Biodegradable mitral annuloplasty for congenital ischemic mitral regurgitation.

An anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is associated with ischemic mitral regurgitation through a combination of papillary muscle ischemia or permanent fibrosis, left ventricular free wall ischemic dyskinesis and left ventricular dilatation. We report the successful management of a 27-month-old girl with ALCAPA and severe mitral regurgitation using a biodegradable mitral annuloplasty ring. It could represent a novel tool for mitral valve repair in ALCAPA-associated ischemic mitral regurgitation.

Ring annuloplasty for ischemic mitral regurgitation: a single center experience.

Ischemic mitral regurgitation associated with coronary artery disease presents a management challenge to cardiac surgeons. We report our early and midterm results of chronic ischemic mitral regurgitation treated with concomitant mitral ring annuloplasty and coronary artery bypass grafting. We performed a retrospective review of the medical records of patients who underwent coronary artery bypass grafting at our institute from January 2009 to December 2011. Data were collected in 50 patients with chronic ischemic mitral regurgitation who had mitral ring annuloplasty along with coronary artery bypass grafting. Preoperative data, echocardiographic findings, operative procedure, outcome, and perioperative hemodynamics were analyzed. Early and intermediate follow-up data were also collected and analyzed. There were 3 (6%) early and 9 (18%) late deaths. Of the survivors, 38 (76%) had a significant reduction in left ventricular end-diastolic and end-systolic dimensions and improvement in New York Heart Association functional class. Despite a risk of residual regurgitation, mitral ring annuloplasty combined with coronary artery bypass appears to be a good treatment option in selected patients with chronic ischemic mitral regurgitation.
