Right ventricular deformation and right ventricular-arterial coupling in patients with heart failure due to severe aortic stenosis undergoing TAVI: long-term results.

ABSTRACT:

Aim

To evaluate the long-term prognostic significance of right ventricular (RV) deformation and RV-arterial coupling in a cohort of patients with heart failure (HF) due to severe aortic stenosis (AS) candidate for trans-catheter aortic valve implantation (TAVI).

Methods

The study is a retrospective analysis of 56 patients undergoing echocardiography before TAVI execution. RV function was defined by tricuspid annular plane systolic excursion (TAPSE), fractional area change (FAC), peak systolic myocardial velocity by tissue Doppler imaging (RVSm) and RV longitudinal strain (RVLS). RV-arterial coupling were defined as TAPSE and RVLS normalized for systolic pulmonary artery pressure (sPAP) to obtain afterload-independent parameters: TAPSE/sPAP and RVLS/sPAP, respectively.
