三尖瓣置换的近期效果

Short-term effects of tricuspid valve replacement

目的：总结三尖瓣置换手术的临床经验。方法回顾性分析2002年12月至2013年12月行三尖瓣置换51例患者的病历资料。结果全部手术均在全麻低温体外循环下施行，体外循环时间平均（105.5±45.9）min，主动脉阻断时间平均（60.7±30.2）min。住院死亡率5.88%，术后1年死亡率2.08%。Logistic 回归分析提示术前心功能、合并手术是术后院内死亡的危险因素。结论三尖瓣置换的早期死亡率是可以接受的，通过积极的围手术期处理，可获得满意的疗效。

Objective To summarize the clinical experiences of 51 patients treated with tricuspid valve replacement（TVR）. Methods The therapeutic methods of 51 TVR patients from December 2002 to December 2013 were retrospectively analyzed. Results All patients were operated under general anesthe-sia and extracorporeal circulation. The mean cardiopulmonary bypass time was（105. 5 ± 45. 9）min and mean aortic block time was（60. 7 ± 30. 2）min. The hospital mortality was 5. 88% and postoperative mor-tality was 2. 08% within the first year. Logistic regression indicated that cardiac function and combined op-erations were risk factors for hospital mortality. Conclusion The early outcomes of TVR are acceptable and it can achieve satisfactory effects through positive perioperative management.
