Deceleration capacity of heart rate predicts 1-year mortality in patients undergoing transcatheter edge-to-edge mitral valve repair.

ABSTRACT:

Background

Risk stratification for transcatheter procedures in patients with severe mitral regurgitation is challenging. Deceleration capacity (DC) has already proven to be a reliable risk predictor in patients undergoing transcatheter aortic valve implantation. We hypothesized, that DC provides prognostic value in patients undergoing transcatheter edge-to-edge mitral valve repair (TEER).

Methods

We retrospectively analyzed electrocardiogram signals from 106 patients undergoing TEER at the University Hospital of Tübingen. All patients received continuous heart-rate monitoring to assess DC following the procedure. One-year all-cause mortality was defined as the primary end point.

Results

Sixteen patients (15.1%) died within 1 year. The DC in nonsurvivors was significan
