Percutaneous aortic valve replacement, or Transcatheter Aortic Valve Implantation (TAVI) or Transcatheter Aortic Valve Replacement (TAVR) is a replacement valve that is delivered via a catheter using one of several access methods: 

  • transfemoral (in the upper leg)
  • transapical (through the wall of the heart)
  • subclavian (beneath the collar bone)
  • direct aortic (through a minimally invasive surgical incision into the aorta)

TAVR is a procedure for select patients with severe symptomatic aortic stenosis (narrowing of the aortic valve opening) who are not candidates for traditional open chest surgery or are high-risk operable candidates. 

TAVR is performed on a beating heart and does not require cardio-pulmonary bypass.
