Present and future use of transcatheter valve for transcatheter aortic valve replacement therapies

Tremendous progress has been made in transcatheter aortic valve replacement（TAVR） therapies in recent years and TAVR has become an alternative treatment to surgical aortic valve replacement（AVR）,with nearly 30 000 procedures performed to date worldwide.Clinical application and investigation of transcatheter valves signify that the future transcatheter valve system will be targeted towards low-profile sheath,long-term efficacy,and safe and precise placement.With wider application and development of transcatheter valves,cumulative experiences and long-term follow-up of TAVR therapies,better criteria will be established for patient selection.Complications will be reduced and safer and more effective treatment results will be achieved.TAVR therapies will be applied to a larger subset of patients and become an important alternative to future conventional aortic valve replacement.
