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 MVP undergoing MV repair, to describe the prevalence and characteristics of MAC, to correlate MAC with clinical risk factors, coronary involvement, and aortic valve disease, and to describe prevalence, site, and extension of MAC in fibroelastic deficiency (FED) versus Barlow's disease (BD) and correlate MAC to surgical outcomes. Despite very high percentage of repairability, MAC influences surgical outcomes and very detailed echo evaluation is advocated.
