Posterior Skirt Technique with Mitral Valve Replacement for Mitral Annular Calcification

Abstract

Severe mitral annular calcification (MAC) presents a surgical challenge due to the complexity of disease and the risk of valve replacement. There have been a variety of techniques to combat this risk including edge-to-edge repair, collar-enforced prosthesis, and pericardial patch techniques. This report highlights a case in which a novel reproducible surgical technique was used to prevent perivalvular leak with mitral valve replacement. This technique may add to surgeons' repertoire in addressing patients with MAC concentrated on the posterior annulus.
