三尖瓣成形对于左心瓣膜置换术后远期三尖瓣返流的预防作用

目的 探讨三尖瓣成形(TA)对于左心瓣膜置换术后远期三尖瓣返流(TR)的预防作用.方法 总结2001年1月-2006年6月105例术前无TR或合并轻度TR的左心瓣膜矫治手术病例.根据术中是否行TA术将患者分为成形组(TA组,n=46)和非成形组(NTA组,n＝59).随访≥5年,复查超声心动图并比较右心室前后径(RV)...

The Effect of Tricuspid Valvuloplasty on Preventing Tricuspid Regurgitation Long after Left-sided Valve Replacement

Objective To discuss the effect of tricuspid valvuloplasty on preventing tricuspid regurgitation(TR) long after left-sided valve replacement.Methods From January 2001 to June 2006 a total of 105 patients complicating slightly TR or not,were undergone left-sided valve replacement.The patients were divided into tricuspid-valvuloplasty group(group TA) and un-tricuspid-valvuloplasty group(group NTA) according to whether performed tricuspid valvuloplasty or not.Each patients was performed echocardiography long term(≥5 years) after surgery,RV,RA,PA,TVAD and the degree of TR were compared between two groups.Results There were no demographic differences between two groups previous surgery.Long after surgery,the RV,RA,PAP and TVAD of group TA were improved;the PAP of group NTA was improved too,but the RV and RA was not improved,and the TVAD was increased;The TVAD of group NTA was greater than group TA,while the number and the degree of TR in group NTA was obviously serious than in group TA.Conclusion TR may take place in patients complicating slightly TR or not long after left-sided valve replacement.Tricuspid valvuloplasty can effectively prevent TR long after surgery.
