老年心脏瓣膜病变的外科治疗体会

Analysis of 160 cases with surgical therapy of heart valve disease in elder patients

目的 总结老年心脏瓣膜病变的外科治疗经验.方法 回顾性分析160例老年心脏瓣膜病变外科治疗患者的临床资料.行二尖瓣置换（MVR）65例,主动脉瓣置换（AVR）45例,双瓣置换50例;同期行三尖瓣成形术108例,冠状动脉搭桥术19例,左房折叠术4例.结果 手术早期死亡6例,死亡率为3.9%.随访140例,随访时间6个月至8年,死亡2例,其余138例术后随诊复查人工瓣膜功能良好,左心室射血分数（LVEF）提高,心功能均提高1～2级,无瓣周漏、人工瓣膜心内膜炎及心脏血栓形成,没有因瓣膜原因而再次手术者.结论 术前充分调整心功能,选择适当的手术时机,加强术中心肌保护,不断改进和提高手术技巧,加强围术期管理,是提高老年心脏瓣膜病变患者手术成功率的关键因素.

Objective To summarize the experience of surgical therapy of heart valve disease in eider patients. Methods Clinical data of 160 cases of surgical therapy with heart valve disease in elder patients from Oet.1997 to Dec. 2007 were retrospectively analyzed, including 65 cases of mitral valve replacement, 45 of aortic valve replacement and 50 of double valve replacement. Meanwhile, 108 cases of tricuspid valvuloplasty, 19 of coronary artery bypass graft and 4 of left atrial wall plieation were performed. Results There were 6 deaths shortly after operation （mortality of 3.9%）. Follow-up ranging from 6 months to 8 years in 140 cases revealed that 138 cases had good heart valve prosthesis function except 2 deaths, left ventricular ejection fraction and heart function improved in all patients as grade I or II （NYHA classification）. There were no periprosthetic leakage, prosthetic valve endocarditis and cardiac thrombosis. There were no more operations attributed to prosthetic valves. Conclusion The well-adjusted preoperative heart function, appropriate selection of surgical opportunity, enhanced protection of intra-operative myoeardium, continuous improvement of surgical techniques and reinforced peri-operative management are the contributing factors to success surgery in the elder patients with heart valve disease.
