RESUMEN
Objective To summarize the clinical experience and efficacy of interventional therapy for pediatric congenital heart disease(CHD) with the Amplatzer Duct Occluder Ⅱ (ADO-Ⅱ). Methods A total of 24 patients had received intervention of CHD with the ADO-Ⅱ,including 18 patients of patent ductus arteriosus(PDA),2 patients of ventricular septal defect(VSD) of muscular part,and 4 patients of coronary artery fistula.All patients were screened by transthoracic echocardiogram before the operations.preoperative. Transthoracic echocardiography was performed to determine the device position, residual shunt and procedural complications during and after ADO-Ⅱ implantation.Results 16 patients with PAD had suecessful transcatheter closure without residual shunt and other complications during the follow-up.Minimal residual shunt was found in 2 PDA patients immediately after the occlusion which became undetectable on control echocardiography the day after operation.3 coronary artery fistula patients had suecessful transcatheter closure without residual shunts,and minimal residual shunt was found in 1 patient with coronary artery fistula at 1 month follow up.All the 2 of VSD patients had suecessful transcatheter closure without residual shunts. No complication and no atrioventricular conduction block were found in these 2 patients. Conclusions Transcatheter closure using the ADO-Ⅱ is safe and effective for interventional therapy for pediatric congenital heart disease.
