Evaluation of transcatheter closure of congenital heart defects with occluder

Objective: To evaluate the therapeutic effect of transcatheter closure of patent ductus arteriosus(PDA),atrial septal defects(ASD) and ventricular septal defects(VSD) using occluder.Methods: Twenty-four patients were treated with occluder through the percutancous procedure under fluoroscopy angiography and transthoracic echocardiography(TEE).Results: The success rate was 100%.No residual shunts were found 24 hours after the procedure and 1 week later.Transesophageal echocardiography(TTE) and X-ray examination showed no residual shunts in all the cases.Conclusions: Transcatheter closure of PDA,ASD and VSD with occluder is a simple and efficient method with a high success rate and good occlusion effect.
