In a series of 833 operations with implantation of 1011 prosthetic valves there were 64 reoperations on 44 patients, an incidence of 7.6%. In almost 50% of the cases, reoperation was motivated by desinsertion. The incidence of desinsertions increased with the number of reoperations. In 40% of the cases, desinsertion was caused by endocarditis. The degeneration of bioprosthetic valves was rapid in children. Thromboembolic accidents occurred in patients with mitral valve mechanical prosthesis. Peri-operative mortality due to left ventricular dysfunction was 9%. Mortality rate was high after reoperation for endocarditis on a desinserted prosthetic valve. Surveillance and prevention of bacterial endocarditis remain of paramount importance.
在833例植入1011枚人工心脏瓣膜的手术中，44例患者进行了64次再次手术，发生率为7.6%。在近50%的病例中，再次手术的原因是瓣膜脱开。瓣膜脱开的发生率随着再次手术次数的增加而上升。在40%的病例中，瓣膜脱开是由心内膜炎引起的。生物瓣在儿童患者中退化迅速。二尖瓣机械瓣置换术后患者发生血栓栓塞事件。因左心室功能障碍导致的围手术期死亡率为9%。因脱开的人工瓣膜心内膜炎再次手术后死亡率很高。细菌性心内膜炎的监测和预防仍然至关重要。
