Analysing on failure in transcatheter closure of ventricular septal defect / 中华超声影像学杂志

ABSTRACT

Objective To analyse the failure reason in transcatheter closure of ventricular septal defect(VSD) ,in order to improve the succeeding rate of occlusive operation on screening VSD patients with echocardiography. Methods Echocardiographic datas were summarized in 50 cases who were failed in VSD occlusion. Results Atrio-ventricular block was occurred in 14 patients,residual shunt was visualized in 13 cases,transcatheter occlusive track could not be set up in 19 cases,arotic valve regurgitation in two cases were screened obviously after occlusive device was released into the intracristal VSD. One case was suffered from cononary heart disease(CAD) and another one was suffered from acute myocardial infarction with ventricular septal perforation. All these patients did not succeed in closure procedure. Conclusions The defect sizes of left and right sides of ventricular septal, structure close to defect must be considered in selecting patients before operation by echocardiography. Occlusion operation should be strictly chosen in cases who were children,or suffered from complex VSD,or senior patients with CAD.
