Rupture of the posterior ventricular wall after mitral valve replacement is a complication rarely reported in the literature. Perforation of the left ventricle after mitral valve replacement with a bioprosthesis has been described in only 3 patients. We have had 2 patients with this complication out of 322 patients who had mitral valve replacement with bioprosthesis. These perforations were caused by impingement of the posterior strut of the bioprosthesis on the posterior left ventricular wall, with intramyocardial hematoma and delayed rupture of the left ventricle.
二尖瓣置换术后心室后壁破裂是一种在文献中很少报道的并发症。二尖瓣生物瓣置换术后左心室穿孔仅在3例患者中被描述过。在322例行二尖瓣生物瓣置换术的患者中，我们有2例出现了这种并发症。这些穿孔是由生物瓣后支柱撞击左心室后壁导致心肌内血肿和左心室延迟破裂引起的。
