机械瓣膜置换术后的随访研究

目的：总结心脏瓣膜病机械瓣膜置换术后疗效，旨在评价心脏瓣膜置换手术的效果及手术后的中长期效果。方法选择本院2000年-2012年我院确诊的心脏瓣膜病患者300例，观察本组患者心脏瓣膜病机械瓣膜置换术后的临床疗效，术后并发症的原因以及发病例数。结果患者的手术之后心功能随访显示，患者心功能与血液动力学出现了很大的改善，并且，大部分患者的劳动能力得到了很大的改善，生活的质量出现了明显的提高。结论我院心脏瓣膜病机械瓣膜置换手术预后整体效果较好，手术的死亡率是可以接受的，和国内的比较并无明显的差别，大部分的患者在手术之后的心功能和生活的质量得到了明显的改善。

A follow-up study of patients treated with mechanical valve replacement

Objective To investigate the postoperative efficacy of mechanical valve replacement in the treatment of valvular heart disease and to evaluate the middle- and long-term outcomes of patients treated with heart valve replacement. Method A total of 300 patients diagnosed with valvular heart disease in our hospital from 2000 to 2012 were included in the study. The clinical efficacy of mechanical valve replacement, causes of postoperative complications, and number of cases of complications were evaluated. Results Postoperative follow-up of cardiac function showed that the treated patients showed substantial improvements in cardiac function and hemodynamics and that most patients had greatly increased ability to work and significantly improved quality of life （QOL）. ConclusionOverall, the patients with valvular heart disease have good outcomes after mechanical valve replacement in our hospital, and the operative mortality is acceptable, with no significant difference compared with the national level; most patients have significantly improved cardiac function and QOL after the operation.
