Percutaneous Aortic Valve Replacement (PAVR)

Percutaneous Aortic Valve Replacement (PAVR), also known as transcatheter aortic valve implantation (TAVI) or transcatheter aortic valve replacement (TAVR), is the replacement of the aortic valve of the heart through the blood vessels (as opposed to valve replacement by open heart surgery). The replacement valve is delivered via one of several access methods: transfemoral transapical, subclavian, direct aortic, and transcaval.
