Transcatheter Closure of Congenital Perimembranous Ventricular Septal Defect in Children Using Symmetric Occluders: An 8-Year Multiinstitutional Experience

The transcatheter approach provides a less-invasive alternative to open surgery and displays some promise in the treatment of pmVSDs in certain patient populations.
