Transcatheter Aortic Valve Replacement (TAVR)
In order to be evaluated for transcatheter aortic valve replacement (TAVR), patients must have severe symptomatic aortic stenosis. Currently, TAVR is approved for use in patients who are considered high risk or not candidates for traditional aortic valve replacement surgery. We are also evaluating lower surgical risk patients and patients with prosthetic aortic valve stenosis or insufficiency in the context of a clinical trial. In many patients, coronary artery disease may be treated at the same time as TAVR.
There are many requirements patients must meet in order to be eligible for TAVR. An extensive multidisciplinary evaluation must be performed as a part of this eligibility process, including assessment of the aortic valve annulus and peripheral vasculature. It is anticipated that the majority of patients will meet these requirements. Patients who do not meet requirements for TAVR may be candidates for conventional aortic valve replacement surgery or for palliative procedures such as balloon aortic valvuloplasty.
