Cardiac Amyloidosis in Patients With Aortic Stenosis

Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasive cardiac interventional procedure that delivers a compressed artificial aortic valve to the diseased aortic valve site via peripheral blood vessels (e.g., the femoral artery) or the apex of the heart through a catheter, releases and deploys the valve to replace the original diseased valve leaflets, thereby restoring normal valve function and treating severe aortic stenosis (AS).
