Ventricular Septal Defect CausesNo one knows what causes ventricular septal defects, but they probably come from a malformation of the heart that occurs while the infant is developing in the womb.
The most common type of ventricular septal defect is the membranous variant. In this type, the hole is located below the aortic valve, which controls flow of blood from the left ventricle into the main artery of the body, the aorta. |
