Objective To access the feasibility, effectiveness and safety of transcatheter closure of ventricular septal defects(VSD) in 17patients. Methods Seventeen patients, aged 4 23 years, were selected by transthoracic echocardiography. The location of VSD was perimembranous in 16 patients and was muscular in 1 patient. And 1 patient with aneurysm formation. All cases had no severe pulmonary hypertension or right to left shunt. Membranous VSD underwent transcatheter closure with Amplatzer membranous VSD occluder or membranous VSD occluder made in China. Muscular VSD was closed by Amplatzer patent ductus arteriosus occluder. Results The VSD diameter ranged from 2.3 10.5 mm(5.75±2.10 mm). The device diameter ranged from 412 mm (7.12±1.67 mm). After application of the prosthesis there was no residual shunt in all patients. One patient developed grade I atrioventricular block and complete right bundle branch block. Two patients developed right bundle branch block after 3 4 days. No other compli...更多cations were observed in 1 12 months follow up. Conclusion The transcatheter closure of VSD appears to be a safe and effective method.
