Influence of transcatheter closure of three cusp VSD occlusion
Objective To investigate the transcatheter occlusion of ventricular septal defect on the effect of tricuspid regurgitation. Methods 203 cases with dielectric closure indications of abdominal ventricular septal defect were treated with interventional therapy on 2011 January to 2013 March in our hospital, according to preoperative three tricuspid regurgitation severity and is associated with pulmonary arterial hypertension, were performed before and after surgery immediately, 3D, 1 months, 3 months and 6 months the echocardiographic examination, observation of three tricuspid valve damage, statistical analysis of light, moderate and severe tricuspid regurgitation occurred in three the proportion of cases. Results 165 cases of successful implementation of patient access operation, 1 cases(0.61%) and three severe tricuspid regurgitation; moderate(2.42%) of 4 cases of mild in 16 cases(9.7%). Observation of the final three tricuspid total reflux ratio of 4.85%. Conclusion In transcatheter closure of ventricular septal defect causes three tricuspid regurgitation or occluder wear tendons, duct injury tendons and conveying rod damage tendons, suggested in the interventional therapy of strict grasp the operation indications, careful manipulation during operation, according to the standard operation, at the same time, pay close attention to structure and morphology ventricular septal defect the surrounding tissue to reduce three, tricuspid regurgitation occurs.
