Muscular ventricular septal defect (VSD) is a congenital heart condition that can affect blood flow in a child’s heart. It’s a common type of heart defect, but if untreated, it can cause a child’s heart and lungs to work harder. At SMS Hospital, we use advanced catheterization procedures to close these holes.
VSD is an opening in the wall (septum) dividing the two lower chambers of the heart (ventricles). Normally, this wall closes before birth. When it doesn’t, oxygen-rich blood in the left chamber can mix with oxygen-poor blood in the right one.
