Right ventricular systolic function in severe tricuspid regurgitation: prognostic relevance of longitudinal strain

doi: 10.1093/ehjci/jeab030
The aim of this study is to analyse the prognostic implications of right ventricular (RV) dysfunction as detected by strain analysis in patients with severe tricuspid regurgitation (TR). The evaluation of RV systolic function in presence of severe TR is of paramount importance for operative risk stratification; however, it remains challenging, as conventional echocardiographic indexes usually lead to overestimation. The study population included 250 patietns with severe TR. Different ranges of RVFWLS have different implications in patients with severe TR, allowing to identify a preclinical and a clinical window, with correlations to RVHF and survival.
