Impact of right ventricular systolic function in patients with significant tricuspid regurgitation. A cardiac magnetic resonance study.

Background: Right ventricle (RV) dilatation and dysfunction are established criteria for intervention in severe tricuspid regurgitation (TR); however thresholds to support intervention are lacking. New measures of RV function such as RV shortening (RVS) and effective RV ejection fraction (eRVEF) may be earlier markers of RV dysfunction.

Purpose: to compare the prognostic impact of different parameters of RV function and to describe cut-off values of RV size/function and TR severity of poor prognosis.
