Ancona F, Melillo F, Calvo F, et al. - Researchers focused on the prognostic implications of right ventricular (RV) dysfunction as identified via strain analysis in patients suffering from severe tricuspid regurgitation (TR). They analyzed 250 consecutive patients experiencing severe TR referred to their centre. Using RV strain analysis [both RV free wall longitudinal strain (RVFWLS) and RV global longitudinal strain], experts recategorized approximately 42–56% of patients exhibiting normal RV systolic function based on conventional parameters in patients with impaired RV systolic function. RV heart failure (RVHF) existence was predicted by RVFWLS ≤ 17%. At follow-up, better survival was experienced by patients with RVFWLS > 14%. Overall, in severe TR cases, different ranges of RVFWLS were shown to have different implications, enabling to detect a preclinical and a clinical window, with correlations to RVHF as well as survival.
