合并三尖瓣中重度反流的膜周部室间隔缺损介入封堵疗效评价

目的 观察合并三尖瓣中重度反流的膜周部室间隔缺损行介入封堵的疗效及远期预后.方法 通过超声心动图选取合并中重度三尖瓣反流的膜周部室间隔缺损患者53例,均无三尖瓣器质性病变,观察行介入封堵后室间隔缺损的封堵效果及三尖瓣反流程度的变化情况.结果 所有室间隔缺损患者均封堵成功,52例三尖瓣反流面积、速度、压差均较随介入时间的...

Evaluation of therapeutic effect of interventional occlusion for perimembranous ventricular septal defect with moderate to severe tricuspid regurgitation

ObjectiveTo observe the therapeutic effect and long-term prognosis of interventional occlusion for perimembranous ventricular septal defect(PMVSD) with moderate to severe tricuspid regurgitation.MethodsFifty-three patients with PMVSD complicated by moderate to severe tricuspid regurgitation were selected by echocardiography, and none of them had organic tricuspid valve disease. The therapeutic effect of interventional occlusion for PMVSD and the changes of tricuspid regurgitation were observed.ResultsPMVSD of all patients was successfully occluded. The area, velocity and pressure difference of tricuspid regurgitation in 52 patients were reduced or decreased with the time of intervention(P＜0.05). One patient had severe tricuspid regurgitation because of occluder intertwined with tendinous cord of tricuspid valve after intervention, and underwent ventricular septal defect repair and tricuspid valvuloplasty. He recovered well after operation.ConclusionAfter strict preoperative screening, interventional occlusion is safe and effective for some PMVSD patients with moderate to severe tricuspid regurgitation.
