Clinical efficiency and safety analysis of transcatheter interventional therapy for compound congenital cardiovascular abnormalities

Abstract

Objective: To investigate the efficiency and safety of transcatheter interventional therapy for compound congenital cardiovascular abnormalities. Methods: From Nov 2001 to Jun 2006, a total of 36 patients (17 male, 19 female), aged 17.20 ± 10.52, with compound congenital cardiovascular abnormalities underwent transcatheter interventional procedure. These patients included 11 with perimembranous ventricular septal defect (PVSD) and patent ductus arteriosus (PDA), 8 patients with PVSD and atrial septal defect (ASD), 8 patients with ASD and PDA, 7 patients with ASD and pulmonary stenosis (PS), 1 patient with ASD and mitral stenosis(MS), 1 patient with coarctation of aorta (COA) and PDA. According to the principle of "easy first, hard second," balloon valvuloplasties of PS or MS were performed before the closure of PVSD, and of PDA and ASD. Electrocardiogram and transthoracic echocardiogram were examined at 4 days, 1, 2, 6 and 12 months, respectively, after each procedure. Results: Transcatheter interventional therapy for compound congenital cardiovascular abnormalities was successful in all patients. Among these, 2 occluders were planted in each of 27 patients, 7 patients with ASD combined with PS and 1 patient with ASD combined with MS underwent successfully performed balloon valvuloplasty and ASD closure, 1 patient with COA combined with PDA underwent successfully performed balloon valvuloplasty and subsequent covered stent implantation. No patient encountered serious adverse events during the (30.5 ± 14.6) months of follow-up. Conclusions: Transcatheter interventional therapy for compound congenital cardiovascular abnormalities could obtain satisfactory results with technical feasibility. © 2007 Wiley Periodicals, Inc.
