Tricuspid regurgitation and outcomes in mitral valve transcatheter edge-to-edge repair.

ABSTRACT:

Background and aims

The association between periprocedural change in tricuspid regurgitation (TR) and outcomes in patients undergoing mitral transcatheter edge-to-edge repair (M-TEER) is unclear. This study aimed to examine the prognostic value of TR before and after M-TEER.

Methods

Patients in the OCEAN-Mitral registry were divided into four groups according to baseline and post-procedure echocardiographic assessments: no TR/no TR (no TR), no TR/significant TR (new-onset TR), significant TR/no TR (normalized TR), and significant TR/significant TR (residual TR) (all represents before/after M-TEER). Tricuspid regurgitation ≥ moderate was defined as significant. The primary outcome was cardiovascular death or heart failure hospitalization. Tricuspid regurgitation pressure grad
