Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure to replace a narrowed aortic valve that fails to open properly (aortic stenosis). Transcatheter aortic valve replacement is sometimes called transcatheter aortic valve implantation (TAVI).
Transcatheter aortic valve replacement is typically reserved for people who can't undergo open-heart surgery or for people for whom surgery presents too many risks.
Transcatheter aortic valve replacement relieves the signs and symptoms of aortic stenosis and improves survival in people who can't undergo surgery or have a high risk of surgical complications.
