52例人工生物瓣膜临床应用分析

目的:总结分析异种心脏生物瓣膜置换的临床应用结果,评价生物瓣膜在瓣膜外科中的应用效果及趋势.方法:回顾性分析2002年6月～2006年6月,在我科接受异种生物瓣膜置换术的患者52例,年龄13～73(52.4±14.0)岁,手术置入生物瓣膜53枚,合用机械瓣膜8枚;同期行双向Clenn分流术1例,B型预激旁路切除术1例,冠脉搭桥术5例;房/室间隔缺损修补4例.结果:术后早期(30 d内)死于多器官功能衰竭1例.平均随访25个月,随访率96%.随访病例生存良好,心功能Ⅰ级41例、Ⅱ级9例、Ⅲ级1例.心脏彩超示瓣膜功能良好,无明显衰败迹象.结论:人工生物瓣膜置换疗效确切,并发症少,在保证手术技术的情况下.近期效果较好.

Retrospective study on clinical application of biovalves in 52 cases

OBJECTIVE: To summarize the clinical application of bioprosthetic valve replacement. METHODS: Fifty two patients, aged 13-73(52.4+/-14.0) years, underwent cardiac valve replacement with biovalves from June 2002 to June 2006 in our hospital. Fifty three tissue valve replacements combined with 8 mechanical valve replacements were performed. Other procedures were also carried out if appropriate, including bidirectional Glenn shunt in 1 patient with double outlet of right ventricle and pulmonary artery stenosis; interruption of accessory pathway in 1 patient with Wolff-Parkinson-White syndrome; coronary artery bypass graft in 5 with severe coronary artery disease; and atrial or ventricular repair in 4 with congenital septum defects. RESULTS: One patient died in hospital due to multiple organ failure. The hospital mortality rate was 1.9%. The mean follow-up was 25 months. Two patients lost follow-up and the follow-up rate was 96%. Forty one patients returned to NYHA class I, 9 to class II, and 1 to class III. Echocardiography showed the implanted bioprosthesis functioned well without stenosis or regurgitation. There was no structural deterioration with freedom from thromboembolism and anticoagulant hemorrhage in all patients. CONCLUSION: The efficacy of biovalves in heart valve replacement is satisfactory.
