超声心动图对继发性三尖瓣反流术疗效的评价

【摘要】〓目的〓通过超声心动图比较继发性三尖瓣反流患者行三尖瓣缝线成形术和成形环成形术的早期和中期效果,评价两种三尖瓣成形方法的疗效。方法〓回顾性分析我院2008年1月~2013年6月行三尖瓣成形术治疗的,并能追踪到而且进行了随访的继发性三尖瓣反流患者 175 例,根据成形方法分成两组:缝线成形术组 143例(82%),使用成形环成形术组 32 例(18%),分别于术前、术后一个月、术后一年通过超声心动图测量左室射血分数(LVEF)、三尖瓣反流束面积(TRA)、三尖瓣反流分数(TRF)、右室前后径(RVD)、右房上下径(RAD1)及右房左右径(RAD2),比较术前、术后半个月及术后1年时各参数的变化。结果〓两组患者,与术前相比,所有患者术后一个月TRA、TRF及RVD、RAD1及RAD2均显著降低(P<0.05),LVEF无显著变化(P>0.05);术后1年,缝线成形术组的患者TRF较术后一个月显著增加(P<0.05),其余指标无明显变化(P>0.05);而使用成形环组术后一年,所有指标较术后一个月无显著变化(P>0.05)。结论〓三尖瓣成形环成形术治疗三尖瓣反流,在术后中期仍可维持良好的疗效。超声心动图对三尖瓣反流的程度可提供半定量信息,在术前及术后随访中有着重要的应用价值。

Value of echocardiography: outcomes of tricuspid annuloplasty for functional tricuspid regurgitation

【Abstract】〓Objective〓To evaluate short-and mid-term outcomes of tricuspid suture annuloplasty and tricuspid ring annuloplasty for functional tricuspid regurgitation by echocardiography. Methods〓From January 2008 to June 2013,175 patients underwent tricuspid annuloplasty for functional tricuspid regurgitation. Two kinds of techniques were used: suture annuloplasty in 143 patients (82%), and ring procedure in 32 patients(18%). LVEF、TRA、TRF、RVD、RAD1、RAD2 were measured by echocardiongraphy preoperatively and postoperatively in one month and one year, and then compared between the two approaches. Results〓The degree of TRA, TRF, RAD1, RAD2 decreased significantly after operation in all patients. There was no significant change of LVEF. TRF were significant larger in one year than that in one month after operation(P<0.05). Other patameters had no significant change during the time after operation in suture annuloplasty group (P>0.05). There were no significant change of the degree of all patameters in one year than those in one month after operation in ring annuloplasty group (P>0.05). Conclusins〓For patients with functional tricuspid regurgitation,the mid-term outcomes were satisfactory by ring annuloplasty. Echocardiography is useful in semi-qualify evaluation of the tricuspid regurgitation pre- and post-operatively.
