超声心动图在“缘对缘”技术治疗Barlow病致二尖瓣关闭不全中的监测作用

The value of echocardiography in the assessment of mitral regurgitation during the ＂Edge-to-Edge＂ technique for the Barlow＇s disease

目的探讨超声心动图监测“缘对缘”技术治疗Barlow病致二尖瓣关闭不全的价值。方法回顾分析我院采用“缘对缘”术式治疗的14例Barlow病患者,利用超声对照观察术前、术中、术后二尖瓣反流量、瓣口面积、左室流出道流速及心功能状态等相关指标。结果术中、术后1周超声显示9例二尖瓣微量反流,5例轻度反流。左室流出道流速术前为（150.5±23.5）cm/s,术后1周为（121.0±26.4）cm/s,差异无统计学意义（P〉0.05）。14例患者随访1～60个月（平均26.8个月）,无死亡及二次手术,二尖瓣口平均面积为（3.0±0.6）cm^2,8例二尖瓣微量反流,6例轻度反流。结论超声心动图在监测“缘对缘”术式治疗Barlow病致二尖瓣关闭不全中具有指导作用,其方法简单易行、安全可靠。

Objective To study the value of echocardiography for the assessment of mitral regurgitation during the ＂Edge-to-Edge＂ technique for Barlow＇s disease. Methods Fourteen Barlow＇s disease patients performed by ＂Edge-to-Edge＂ operation were analyzed retrospectively from April 2000 to April 2005 by comparing the the degree of mtiral regurgitation, mitral valve area, the velocity of left ventricular outlet and the parameters of cardiac function pre- and postoperatively by echocardiography. Results The echocardiography during and after operation show that there were 9 cases of trivial regurgitant and 5 cases of mild regurgitant. The outflow velocity was （ 150.5 ± 23.5） cm/s preoperatively and （ 121.0 ± 26.4）cm/s postoperatively （ P 〉0.05）. In follow-up of 14 patients from 1 to 60 months（the mean value was 26. 8 months）, there was no death and re-operation. The average mitral valve area was（3.0±0. 6）cm^2. There were 8 cases of trivial regurgitation and 6 cases of mild regurgitation. Conclusions Echocardiographic assessment is feasible and effective during the ＂Edge-to-Edge＂ technique for mitral regurgitation caused by Barlow＇s disease.
