Calcification of the mitral annulus is always a technical complication in mitral surgery and standard procedures are often difficult to perform; mitral valve replacement can be dangerous with a high risk of perioperative heart rupture, and reconstructive surgery is often contraindicated. Nevertheless in this case of posterior leaflet prolapse with annular calcification valve repair was performed, after complete calcium debridement causing annulus disruption and atrio-ventricular discontinuity, by means of a straddling atrio-ventricular pericardial patch and the sliding leaflet technique.
二尖瓣环钙化一直是二尖瓣手术中的技术难题，标准手术操作往往难以实施；二尖瓣置换术可能很危险，围手术期心脏破裂风险很高，重建手术通常也属禁忌。然而，在这个后叶脱垂伴瓣环钙化的病例中，在彻底清除钙化导致瓣环破裂和房室连续性中断后，通过跨越房室的心包补片和滑动瓣叶技术进行了瓣膜修复。
