Contemporary experience of mitral transcatheter edge-to-edge repair technology in patients with mitral annular calcification.

Background: Mitral annular calcification (MAC) has been an exclusion for many of the earlier pivotal trials that were instrumental in gaining device approval and indications for mitral transcatheter edge-to-edge repair (M-TEER).

Aims: To evaluate the impact of MAC on the procedural durability and success of newer generation MitraClip® systems (G3 and G4 systems).

Methods: Data were collected from Northwell TEER registry.
