Left ventricular rupture is reported to occur in 0.5-2% of patients following mitral valve replacement and results in a high mortality rate. Three types of left ventricular rupture have been identified, each attributed to a different mechanism. Failure of repair has been due to repeated tearing of the ventricular muscle and resulting hemorrhage. We describe the repair of left ventricular rupture following mitral valve replacement with buttressed dacron patch. The repair is designed to eliminate the tension placed on the suture line. In addition, specific recommendations are made to avoid left ventricular rupture during mitral valve replacement.
据报道，二尖瓣置换术后0.5%-2%的患者会发生左心室破裂，死亡率很高。已确定三种类型的左心室破裂，每种类型都归因于不同的机制。修复失败是由于心室肌肉反复撕裂并导致出血。我们描述了使用带支撑的涤纶补片修复二尖瓣置换术后的左心室破裂。该修复旨在消除缝合线上的张力。此外，还提出了具体建议以避免二尖瓣置换术中发生左心室破裂。
