Biventricular Repair

Also known as: complex biventricular repair, biventricular repair procedure

What is biventricular repair?

If a child is born with some forms of single ventricle heart defects (SVD), which cause the lower chambers of the heart to not work correctly, then a biventricular repair is a potential surgical treatment for them in some cases. There are different types of biventricular repair depending on the type of defect that is present, and not all children are candidates for the procedure.

What happens during the procedure?

The exact nature of the procedure will vary based on the defect that is present. In some cases, it involves several procedures over a number of months or years to fully repair the child’s ventricles. In other cases, a child may be a candidate to receive a complete biventricular repair that fully reconstructs the heart’s ventricles with one procedure. The procedures are all surgeries that are performed under general anesthesia and require a multi-day stay in the hospital.

Is any special preparation needed?

Your child will likely need to undergo several diagnostic tests to determine if they are a candidate for biventricular repair and, if so, which procedure or procedures are appropriate for them. Your doctors may have other guidance depending on the specific nature of the procedure or procedures. For example, you may need to avoid food and medication for a period of time before the procedure.

What are the risk factors?

A biventricular repair procedure does have risks and may involve multiple surgeries, so it’s important to discuss these risks and potential outcomes with your doctors. Despite the risks, in many cases it’s the best treatment option available for the infant with a congenital heart defect, and many children who have undergone the procedure go on to lead healthy, productive lives.
