Are there percutaneous procedures to replace a diseased aortic valve?
Yes. Two devices for replacing these valves have been approved in Europe, and several hundred patients worldwide have been treated using percutaneous procedures. In the United States, a feasibility trial has been completed for replacing the aortic valve, and a randomized clinical trial has just begun for patients who are high risk for conventional aortic valve replacement. This procedure may also be used to replace the pulmonary valve, which controls blood flow between the heart and the arteries that carry blood between the heart and lungs and is a problem for some children and adults with congenital heart disease.
