Ross-Konno Procedure

Also known as: pulmonary autograft.

What is Ross-Konno procedure?

Ross-Konno procedure is a surgery to repair a damaged aortic valve. The aortic valve is responsible for pumping blood from the heart out to the body. The left ventricular outflow tract is also enlarged as part of the Ross-Konno procedure.

What happens during the procedure?

The Ross-Konno procedure is an open-heart surgery done under general anesthesia and cardiopulmonary bypass. It involves removing the damaged aortic valve, removing the pulmonary valve, and putting the pulmonary valve in place of the damaged aortic valve. Then a donated pulmonary valve (animal or human) is attached in place of the removed pulmonary valve. The left ventricular outflow tract is also enlarged to enhance blood flow.

Is any special preparation needed?

You may need to avoid food or drink, as well as certain medications, for a period of time before the procedure.

What are the risk factors?

The risks of Ross-Konno procedure include bleeding, stroke, heart attack, infections, breathing problems, drug reactions, arrhythmia and possibly death.
