Aortic Stenosis and Transcatheter Aortic Valve Implantation: Current Status and Future Directions in Korea

Abstract

Transcatheteraorticvalveimplantation(TAVI) has been accepted as one of primary options for treatment of symptomatic severeaorticstenosis. Although TAVI has been predominantly used for patients at high risk or with old age who were not considered optimal candidates for surgicalaorticvalvereplacement (SAVR), its indication is now expanding toward low risk profile and younger age. Many clinical trials are now ongoing to test the possibility of TAVI for use in patients even with uncharted indications who are not eligible for SAVR incurrentguidelines but may benefit fromvalvereplacement.Currentissues including periprocedural safety, long-term adverse events, hemodynamics and durability associated with TAVI should be also solved for expanding use of TAVI. The review presentscurrentstatusandfuturedirectionsof TAVI and discusses perspectives inKorea.
