            TERMINOLOGY

            • Abbreviations

              • Transcatheter aortic valve replacement (TAVR)
            • Synonyms

              • Transcatheter aortic valve implantation (TAVI)
              • Percutaneous aortic valve replacement
            • Definitions

              • TAVR is percutaneous deployment of bioprosthetic valve in aortic root
                • Endovascular access point for delivery of valve is commonly femoral artery; however, other options include left ventricular transapical approach
                • It is treatment of choice for patients with aortic stenosis at high or intermediate surgical risk and as alternative for those at low surgical risk
