Right Atrial-to-Right Ventricular Area: Prognostic Value in Patients With Secondary Tricuspid Regurgitation and Heart Failure.

ABSTRACT:

Background

Severe secondary tricuspid regurgitation (STR) in heart failure patients is associated with excess mortality. Quantification associated risk assessment, remains challenging, specifically with contextual anatomic variability. Recent observations identified different morphological STR substrates based on predominance of ventricular or atrial remodeling, the extent of which can be expressed as right atrial/right ventricular area (RA/RV) ratio.

Objectives

This study aims to investigate prognostic implications of RA/RV ratio in patients with STR.

Methods

This observational study included 13,174 STR patients, 1,219 had severe STR. Patients were allocated to predominant atrial remodeling (RA/RV ratio ≥1.17) vs predominant ventricular remodeling (RA/RV ratio <1.17)
