Hole in the heart, also known as ventricular septal defect (VSD), is a heart defect that exists since birth. The defect is present in the wall that separates the ventricles and allows blood to pass from the left to the right side of the heart. The heart will have difficulty in working if the oxygen-rich blood get pumped back the lungs instead of going to the body.
A surgical procedure is needed immediately for children who have medium to large VSDs to prevent future complications. Some small VSDs have no further medical issues because they may close on their own.
