ⓘ Ventricular septal defect
A ventricular septal defect is a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart. The extent of the opening may vary from pin size to complete absence of the ventricular septum, creating one common ventricle. The ventricular septum consists of an inferior muscular and superior membranous portion and is extensively innervated with conducting cardiomyocytes.
The membranous portion which is close to the atrioventricular node, is most commonly affected in adults and older children in the United States. It is also the type that most often require surgical intervention, consisting of more than 80% of cases.
Membranous septal defects are more common than muscular ventricular septal defects, and are the most common congenital heart defect.
