While open-heart aortic valve replacement surgery is the gold standard treatment for severe symptomatic native aortic valve stenosis, there are patients who are not candidates for open-chest surgery. These inoperable patients may be unable to undergo traditional surgery because of factors such as age, history of heart disease, frailty or other health issues. For these patients, a new therapy called transcatheter aortic valve replacement (TAVR) may be an option. TAVR is a procedure that allows the Heart Valve Team to replace a diseased aortic heart valve without open-heart surgery. This procedure enables the placement of a balloon-expandable heart valve into the body with a tube-based delivery system (catheter), which allows the valve to be inserted through a small cut in the thigh into an artery or through a small apical incision.
