Objective: This study aims to assess the clinical efficiency and safety of simultaneous transcatheter interventional treatment for perimembranous ventricular septal defect (pmVSD) combined with patent ductus arteriosus (PDA).
Methods: Twenty-five patients with pmVSD and PDA treated with simultaneous transcatheter interventions from April 2004 to December 2015 were included in this study. The mean age was 9.80 ± 8.14 years and the mean weight was 29.76 ± 14.82 Kg. Transthoracic echocardiography (TTE) and angiography were performed immediately after the procedure. Patients were re-examined by electrocardiogram, X-ray, and TTE at 2 days, 1 month, 3 months, and 6 months postoperatively.
Results: The interventional procedure was successfully performed in all 25 patients. No intraoperative complication was noted. TTE examination of the VSD and PDA immediately after the procedure showed no residual shunt and the occluder was well positioned. Among these patients, four patients showed electrocardiogram changes after the procedure that resolved after drug therapy. The cardiothoracic ratio, left atrial diameter, left ventricular end-systolic diameter, and left ventricular end-diastolic diameter recovered to normal in most patients at 6 months postoperatively.
Conclusions: Simultaneously transcatheter interventional therapy is a safe and effective method for pmVSD combined with PDA.
