This document discusses non-surgical interventions for atrial septal defects (ASD) and ventricular septal defects (VSD). It describes the anatomy, causes, symptoms, and types of ASDs and VSDs. It also discusses percutaneous closure as a common non-surgical treatment for secundum ASDs using devices like the Amplatzer Septal Occluder. Percutaneous closure is presented as the preferred method over surgery for most centers. The document concludes by restating the core values of care, coordination, and providing the smoothest patient experience for complex congenital heart disease repairs.
