Prognosis of persistent mitral regurgitation in patients undergoing transcatheter aortic valve replacement.

ABSTRACT:

Objective

The objective of this study was to assess imaging predictors of mitral regurgitation (MR) improvement and to evaluate the impact of MR regression on long-term outcome in patients undergoing transcatheter aortic valve replacement (TAVR).

Background

Concomitant MR is a frequent finding in patients with severe aortic stenosis but usually left untreated at the time of TAVR.

Methods

Mitral regurgitation was graded by transthoracic echocardiography before and after TAVR in 677 consecutive patients with severe aortic stenosis. 2-year mortality was related to the degree of baseline and discharge MR. Morphological echo analysis was performed to determine predictors of MR improvement.

Results

15.2% of patients presented with baseline MR ≥ 3 +, which was associa
