A '''ventricular septal defect''' (or VSD) is a defect in the ventricular septum (the wall dividing the left and right ventricles of the heart).

Overview
A ventricular septal defect (or VSD) is a defect in the ventricular septum (the wall dividing the left and right ventricles of the heart). The ventricular septum consists of a muscular (inferior) and membranous portion (superior). The membranous portion (which is close to the atrioventricular node) is most commonly affected.[1]
Congential VSDs are collectively the most common congenital heart defect.[2]
