保留后瓣并行前瓣腱索重建的二尖瓣置换术效果分析

The effect analysis of the mitral valve replacemen with preserve after valve and rebuild before valve chordae

目的:探讨保留后瓣并行前瓣腱索重建的二尖瓣置换对患者术后心功能恢复效果的影响及预后。方法:选取35例采用保留后瓣并行前瓣腱索重建的二尖瓣置换术患者(其中我院在2016年6月至2017年6月开展10例,另外25例,为上海远大心胸医院在2014年12月至2015年12月期间开展),通过术后LVEF、LVEDD等功能指标与术前对比进行分析,评价该术式对患者术后心功能恢复的影响及预后。结果:35例患者无手术死亡,术后未出现左心室破裂及左心室壁血肿。术后7d复查LVEF、LVEDD与术前指标对比明显改善,差异有统计学意义(P<0.05)。结论:保留后瓣并行前瓣腱索重建的二尖瓣置换手术是一种安全的、可行的、有效的手术方式,在解决二尖瓣狭窄的情况下能较好的维护左心室功能。

Objective： To explore the effect of the mitral valve replacement with preserve after valve and rebuild before valve chordae on cardiac function recovery after operation. Methods： Selected thirty-five patients of MVR with preserve after valve and rebuild before valve chordae（ 10 cases of our hospital from June2016 to June 2017,25 cases of Shanghai Yodak Cardio-Thoracic Hospital from December 2014 to December2015）,contrast the patient＇ s indicatorsof cardiac functions such as LVEF、LVEDD before and after the operation,to evaluate the effect and prognosis of this operation on cardiac function recovery after operation. Results：None of these patients died and no left ventricular rupture occurred after the operation. The comparison between postoperative and preoperative index such as LVEF、LVEDD was significantly improved after 7 days after surgery,There are statistical differences（ P 〈0. 05）. Conclusion： The mitral valve replacemen with after valve preservation and rebuild before valve chordae is a safe and viable operative method,The left ventricular function can be maintained well in the case of solve the problem of mitral valve stenosis.
