Prognostic Value of the Right Ventricular-to-Left Ventricular Volume Ratio in Tricuspid Regurgitation.

ABSTRACT:

Background

Tricuspid regurgitation (TR) is associated with right ventricular (RV) remodeling; however, conventional RV metrics may not fully reflect the interplay between the right and left ventricles.

Objectives

The aim of the study was to examine the prognostic value of the right ventricular-to-left ventricular volume ratio (RV/LV_vol) ratio in TR.

Methods

A retrospective analysis was conducted on 949 patients with ≥moderate TR who underwent cardiac magnetic resonance imaging between 2005 and 2024. The RV/LV_vol ratio was assessed as a dichotomous variable (normal: <1.27, abnormal: ≥1.27) and by severity strata. Follow-up data, including all-cause mortality, were collected using the Social Security Death Index and electronic medical records.
