WebVSD is an opening or hole (defect) in the wall (septum) separating the two lower chambers of the heart (ventricles). In normal development, the wall between the chambers closes before the fetus is born, so that by birth, oxygen-rich blood is kept from mixing with the oxygen-poor blood. When the hole does not close, it may cause higher pressure ...
