Type I myocardial rupture due to atrioventricular discontinuity in the region of the posterior mitral annulus is a fearsome and nearly unpredictable complication of mitral valve replacement. We report a case of a 49-year-old patient who had been operated on for mitral valve replacement. The posterior mitral leaflet had heavy calcifications embedded through the annulus in the posterior ventricular wall. After removal of calcifications we avoided the risk of myocardial rupture by suturing a straddling pericardial patch on the atrioventricular junction. The operation resulted in complete recovery.
二尖瓣后瓣环区域房室不连续导致的I型心肌破裂是二尖瓣置换术可怕且几乎无法预测的并发症。我们报告一例49岁接受二尖瓣置换手术的患者。二尖瓣后叶有严重钙化，钙化嵌入后室壁的瓣环。去除钙化后，我们通过在房室交界处缝合跨骑心包补片避免了心肌破裂的风险。手术使患者完全康复。
