Prevalence of calcification of the mitral valve annulus in patients undergoing surgical repair of mitral valve prolapse

The aims of this study were, in patients with mitral valve (MV) prolapse (MVP), undergoing MV repair, (1) to describe the prevalence and characteristics of mitral annulus calcification(MAC) (2) to correlate MAC with clinical risk factors, coronary involvement, and aortic valve disease, and (3) to describe prevalence, site, and extension of MAC in fibroelastic deficiency  versus Barlow's disease and correlate MAC to surgical outcomes (repair vs replacement).
