Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure used to replace the aortic valve in people with severe aortic stenosis. Aortic valve stenosis is a condition where the aortic valve is narrowed and doesnt open fully, which blocks or slows blood flow from the heart to the body. TAVR is a less invasive alternative to open-heart valve surgery and uses smaller incisions. During the procedure, a doctor inserts a flexible, hollow tube called a catheter into a blood vessel in the leg or chest and guides it to the heart. A replacement valve goes through the tube and is placed in the area of the aortic valve. A balloon on the catheter tip widens to press the new valve into place. Some TAVR valves expand without the use of a balloon. The procedure is performed using one of two approaches, allowing the cardiologist or surgeon to choose which one provides the best and safest way to access the valve. TAVR can help reduce chest pain, shortness of breath, and other symptoms of aortic valve stenosis. The decision to have TAVR is made after talking with a team of heart doctors and heart surgeons, who work together to determine the best treatment option for the patient. TAVR is available to patients in all risk categories and can be an effective option to improve the quality of life in patients who otherwise have limited choices for repair of their aortic valve. However, TAVR is still a major procedure that has risks, including damage to blood vessels, bleeding, decreased blood supply to the brain, heart attack, kidney failure, and collection of fluid around the heart.
