Ventricular septal defects (VSD)
Treatment options for ventricular septal defects depend on the size of the opening in the ventricle. Almost 50 percent of VSDs are small and close spontaneously shortly after birth, requiring no further treatment. Larger defects need to be closed, often before the age of 1. Ventricular septal defects often occur in conjunction with other heart defects, therefore treatment is highly individualized.
Isolated VSDs may be closed using a cardiac catheterization procedure. Commonly a small patch resembling a parachute is placed over the opening using a catheter; however, there are a variety of other patches that can be used as well. The cardiologist uses a catheter that enters the body through a leg or arm to place the patch. More detail about heart catheterization can be found in the testing section.
Not all VSDs are suitable for catheterization; in these cases heart surgery is necessary to close the VSD. This may be due to the location or size of the VSD or because the VSD occurs with other congenital defects. The procedure is highly individualized depending upon the patient's situation.
