Treatment
Many babies born with a small ventricular septal defect (VSD) won't need surgery to close the hole. After birth, your doctor may want to observe your baby and treat symptoms while waiting to see if the defect closes on its own.
Babies who need surgical repair often have the procedure in their first year. Children and adults who have a medium or large ventricular septal defect or one that's causing significant symptoms may need surgery to close the defect.
Some smaller ventricular septal defects are closed surgically to prevent complications related to their locations, such as damage to heart valves. Many people with small VSDs have productive lives with few related problems.
Babies who have large VSDs or who tire easily during feeding may need extra nutrition to help them grow. Some babies may require medication to help treat heart failure.
