This study aimed to explore the mechanism of membranous ventricular septal defect complicated with tricuspid regurgitation and the significance of ventricular septal defect occlusion by echocardiography. A total of 43 patients with membranous ventricular septal defect complicated with tricuspid regurgitation were observed by echocardiography and the changes in length, area and volume of tricuspid regurgitation prior to and following ventricular septal defect occlusion were measured. There were four different mechanisms of membranous ventricular septal defect complicated with tricuspid regurgitation. The various indices of tricuspid regurgitation volume were significantly reduced following occlusion. Ventricular septal defect occlusion significantly reduces tricuspid regurgitation volume complicated with membranous ventricular septal defect and echocardiography is an ideal method to detect these changes.
本研究旨在探讨膜周部室间隔缺损合并三尖瓣反流的机制及超声心动图引导下室间隔缺损封堵术的意义。对43例膜周部室间隔缺损合并三尖瓣反流患者行超声心动图检查,测量室间隔缺损封堵术前、后三尖瓣反流束长度、面积及反流容积的变化。膜周部室间隔缺损合并三尖瓣反流存在四种不同机制。封堵术后三尖瓣反流的各项指标均显著降低。室间隔缺损封堵术可显著降低膜周部室间隔缺损合并的三尖瓣反流容积,超声心动图是检测这些变化的理想方法。
