Real-World Outcomes of the Initial Clip Selection for Transcatheter Edge-to-Edge Repair Using the MitraClip G4 From the Optimized Catheter Valvular Intervention-Mitral Registry.

ABSTRACT:

Background

The association of outcomes with initial clip selection has not been investigated in patients undergoing transcatheter edge-to-edge repair with the MitraClip G4.

Methods

We analyzed 2257 patients receiving the MitraClip G4 according to the initial clip type: short (NT/NTW) versus long (XT/XTW) and narrow (NT/XT) versus wide (NTW/XTW). We performed a propensity-matched analysis of baseline anatomical features in patients with primary and secondary mitral regurgitation (MR).

Results

The proportions of the initial clip types were as follows: NT, 18.9%; NTW, 41.7%; XT, 5.1%; and XTW, 34.3%. The proportions of the MR severity ≤1+ at discharge and 1 year were not significantly different among the 4 clip types. The incidence of death or heart failure hospitalizati
