The initial cost for TAVR, along with care before and after the procedure (including both hospital and physician fees), was roughly $78,000, with the commercial cost for the new valve system estimated at about $30,000.
Currently, this is an option for patients with severe aortic stenosis causing symptoms that are too high risk for standard valve replacement surgery. During a TAVI or TAVR procedure, a catheter about the size of a pen, is inserted in the artery in the leg and carefully passed up into the heart. One type of TAVR valve, made of bovine (cow) tissue and supported on a metal stent, is then implanted inside the narrowed valve resulting in a normal functioning aortic valve. With a TAVR procedure, the patient does not need the chest opened for surgery or put on a heart-lung (bypass) machine.
