25 Transcatheter MV Replacement More than 30 in development! Potential advantages (vs. repair) 1. Applicable to primary and secondary MR, regardless of anatomy or pathology 2. Ease of implantation (?) 3. Reliable elimination of MR 4. Greater durability?

26 New TMVR Systems First in Human Timelines

27 Early Feasibility Studies in US TMVR

28 Currently in Trials in US Tendyne CardiaQ Caisson Intrepid

32 Mitral Valve Disease Major Unanswered Questions Does MR need to be completely corrected? Can primary MR be corrected sufficiently by a transcatheter approach? Does correction of secondary MR improve survival or quality of life? Which is preferable for secondary MR- repair or replacement?
