Outcomes of Combined Left Atrial Appendage Occlusion and Transcatheter Mitral Edge-to-Edge Repair: The WATCH-TEER Study.

ABSTRACT:

Background

Up to 50% of patients undergoing mitral transcatheter edge-to-edge repair (MTEER) have an indication for left atrial appendage occlusion (LAAO). However, prospective evaluation of this strategy is lacking.

Objectives

The aim of the study was to prospectively evaluate the outcomes of combined LAAO and MTEER.

Methods

The WATCH-TEER study is a prospective multicenter registry that aims to assess the feasibility and safety of concomitant MTEER with MitraClip and LAAO with WATCHMAN-FLX in patients with an approved clinical indication for both procedures. The primary endpoint was a composite of all-cause mortality, stroke, life-threatening, or major bleeding at 45 days.

Results

A total of 24 patients were included between October 2020 and March 2024. Mean
