Transcatheter Aortic Valve Replacement (TAVR) is a valuable option for patients with severe aortic stenosis who are not candidates for open-heart surgical Aortic Valve Replacement (AVR).Severe aortic stenosis is a narrowing of the aortic valve that prevents blood from flowing through the valve freely.This can be caused by a birth defect, radiation therapy, rheumatic fever, or age.In TAVR, a new valve is implanted inside the patient's own narrowed valve. As a result, blood flow through the heart and body increases.Listen in as David Butzel, MD discusses TAVR and how Maine Medical is in the forefront in preforming this procedure.
