心脏人工机械瓣膜置换术100例报告

100 Cases of Artificial Heart Valve Replacements

目的 总结 10 0例心脏瓣膜置换术。方法 全组均在全麻体外循环中低温下手术 ,行二尖瓣置换(MVR) 6 5例 ,主动脉瓣置换 (AVR) 19例 ,二尖瓣和主动脉瓣置换 (MAVR) 16例 ,其中 14例是二尖瓣狭窄术后再狭窄行置换术 ,同时行三尖瓣 De Vega s环缩术 15例。结果 术后 93例痊愈出院 ,围手术期死亡 7例 ,均为风心病患者。结论 风湿性心脏病 (RHD)是导致心脏瓣膜损毁的主要病因 ,感染性心内膜炎 (IE)和退行性变也是较常见的因素 ,而早期诊断、及时手术是提高治愈率、降低并发症的关键。

Objective:To review the experience of the heart valve replacements.Methods:All patients underwent general anesthesia under middle hypothermic cardiopulmonary bypass(CBP).Operations included MVR in 65 cases,AVR in 19 cases,MAVR in 16 cases.Second operations had 14 patients of restenosis after mitral valve stenosis dilatation.Additional procedures included tricuspid valve De Vegas annuloplasty in 15 cases.Results:93 patients recovered uneventfully and returned to normal life.There were 7 cases of postoperative death with a mortalily of 7%.Conclusion:Main factor of heart valve diseases suffered from RHD.Infective endocarditis and degenerate heart diseases were often seen in the clinic.The study suggests that the surgical early diagnosis and effective treatment can achieve excellent outcome with low complications and high cure rates.
