Outcomes and predictors of left ventricle recovery in patients with severe left ventricular dysfunction undergoing transcatheter aortic valve implantation.

ABSTRACT:

Background

Data on the likelihood of left ventricle (LV) recovery in patients with severe LV dysfunction and severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) and its prognostic value are limited.

Aims

We aimed to assess the likelihood of LV recovery following TAVI, examine its association with midterm mortality, and identify independent predictors of LV function.

Methods

In our multicentre registry of 17 TAVI centres in Western Europe and Israel, patients were stratified by baseline LV function (ejection fraction [EF] >/≤30%) and LV response: no LV recovery, LV recovery (EF increase ≥10%), and LV normalisation (EF ≥50% post-TAVI).

Results

Our analysis included 10,872 patients; baseline EF was ≤30% in 914 (8.4%) patients and >30%
