Abstract:
Objective To probe the value of using echocardiography in transcatheter closure of ventricular septal defect (VSD).Methods Under transthoracic echocardiography and digital subtraction angiocardiography monitoring and guidance in the operation,the Amplatzer excentric umbrella occluder was used to occlude the perimembranous defects in 15 cases of patients.Results All of the patients were treated successfully,though mitral regurgitations or residual shunts occurred in 6 cases,and disappeared at once after the position and direction of occluder were regulated in 3 and these complications disappeared gradually one month postoperation in other 3 patients.The umbrella separated from VSD in 1 and occluded successfully when manipulated once again.Complete heart block occurred in 2 and disappeared after 3 days.The positions of umbrella were normal and stable and no other complications were discovered when these patients were followed about 10 months the longest.Conclusions Echocardiography plays an important role in transcatheter closure of VSD with the Amplatzer occluder before,during and after operation and in the period of follow up.
