What is a VSD (Ventricular Septal Defect)?
A ventricular septal defect (VSD) is one of the most common congenital heart defects. A wall or septum divides the ventricles, the pumping chambers of the heart. In some developing hearts, the septum does not completely divide the two ventricles. A hole in the septum is classified as a ventricular septal defect. Many may have heard the term a “hole in the heart,” which usually refers to a VSD.
