Heart Valve Repair and Replacement

#6

Cardiology

Heart valves are flaps, or leaflets, of tissue that ensure that blood entering or leaving the heart moves in the proper direction, with no backflow. The heart and its great vessels have four valves: the mitral valve, tricuspid valve, aortic valve, and pulmonary valve. Valvular disease can affect any of these valves and interfere with the normal flow of blood through the heart. Heart valves that are defective may either be repaired or replaced with a tissue or mechanical substitute, depending on the nature and severity of the condition.

Care at NewYork-Presbyterian

NewYork-Presbyterian's heart valve programs are led by pioneers in the field. Our doctors were the principle investigators of the national clinical trials establishing the effectiveness of Transcatheter Aortic Valve Replacement (TAVR). They were leaders in the development and evaluation of novel, less invasive techniques for repairing and replacing damaged mitral, aortic, and pulmonary valves. They also played a leading role in the clinical trials assessing the latest percutaneous valve replacement approaches.
