Abstract
Background Cardiac MRI has been shown to be the gold standard for noninvasive assessment of myocardial fibrosis. The extent of fibrosis has been associated with worse outcomes in patients undergoing CABG surgery. The presence of fibrosis and associated clinical features of patients with chronic mitral regurgitation undergoing mitral valve repair have not been described. The objective of this study is to examine prognostic value of preoperative myocardial fibrosis assessment by cardiac MRI in patients with chronic mitral regurgitation undergoing mitral valve repair.
