Regional wall motion abnormalities and scarring in severe functional ischemic mitral regurgitation: a pilot cardiovascular magnetic resonance imaging study.

摘要

We read with interest Flynn and colleagues' article1 concerning preopera-tive evaluation with cardiac magnetic resonance imaging (MRI) in patients undergoing coronary artery bypass grafting and mitral valve annuloplasty for ischemic mitral valve regurgitation (DVIVR).In our experience, cardiac MRI has been advocated for preoperative routine evaluation of patients with IMVR since 2006. In a cohort of patients with coronary artery disease and depressed left ventricular ejection fraction, IMVR seemed to occur mainly whenever a transmural area of delayed enhancement (necrosis) was present at cardiac MRI within the inferior myocardial segments.
