ABSTRACT
Introduction Transcatheter closure of selected perimembranous and muscular ventricular septal defects (VSDs) using various devices is gaining increasing acceptance in the pediatric cardiology community.1-8 Even though transcatheter closure avoids the inherent risk of cardiopulmonary bypass, surgical closure remains the therapy of choice for VSDs. Any new procedure will be measured against this gold standard. In order for an interventional procedure to be accepted as an alternative therapeutic choice, its outcome must be at least comparable to surgical results with regard to its efficacy and safety.
