Transcatheter Aortic Valve Replacement (TAVR) is a procedure for select patients with severe symptomatic aortic stenosis (narrowing of the aortic valve opening) who are not candidates for traditional open chest surgery or are high-risk operable candidates.

The TAVR procedure enables the placement of a balloon expandable aortic heart valve into the body via the catheter-based transfemoral delivery system. The TAVR procedure is designed to provide an alternative treatment to patients in whom the traditional open-heart surgery can not be performed.
