Ten Future Challenges in the Field of Transcatheter Mitral Valve Edge-to-Edge Repair

Mitral valve transcatheter edge-to-edge repair (M-TEER) and replacement (TMVR) have evolved as guideline-recommended treatment approaches for mitral regurgitation (MR). Even though they are supported by a growing body of evidence from either randomized trials or large registries, there are still several unsolved challenges in the field of interventional MR treatment. In the present review, we discuss the ten most important open questions regarding M-TEER and TMVR.
