Objectives To probe the safety and clinical results of interventional therapy of residual shunts after surgery repair of congenital heart disease.

Methods A total of 10 patients (6 males and 4 females) with residual shunt after surgery repair underwent transcatheter intervention therapy from January 2004 to April 2011, including 7 patients with residual shunt after surgery repair of ventricular septal defect (VSD),2 patients with residual shunt after surgery repair of patent ductus arteriosus (PDA),1 patient with residual shunt after surgery repair of atrial septal defect (ASD). Their mean age was (27.6±10.8) years. Their mean weight was (59.2±7.6) kg. Follow-up with electrocardiogram (ECG) and transthoracie echocardiography (TTE) was undertaken 2 d, l m, 3 m, 6 m and 12 m after the procedures.

Results Ten patients were treated successfully. No patient encountered complications during follow-up.

Conclusions Transcatheter closure of residual shunts after surgery repair of congenital heart disease is safe, effective and feasible.
