<p>In this systematic review, we aimed to analyze the methods and results of studies dedicated for quantifying tricuspid regurgitation (TR) with cardiac magnetic resonance (CMR), the concordance between echocardiography and CMR, the prognostic value and the reproducibility of CMR in patients with TR. Published studies on MEDLINE were included using search terms on TR and CMR until June 2024. Out of the 1108 screened articles, 19 studies fulfilled our inclusion criteria. The 2 most commonly used methods were the indirect method which uses 2D-phase contrast (2D-indirect) and the challenging measurement of right ventricular stroke volume. It was used in larger studies with higher proportion of patients with severe TR. The direct method, which uses 4D-phase contrast (4D-direct), has been mainly used in methodological studies with a low proportion of patients with severe TR. 4 studies comparing CMR with echocardiography showed poor severity agreement. In 6 studies assessing the prognostic value of CMR, TR evaluation with tricuspid regurgitant volume (RVol) or regurgitation fraction (RF) yielded a strong prognostic value although right ventricular ejection fraction was the most consistent prognostic predictor. There was very good inter-/intra-observer variability in 8 studies. No study with inter-examination evaluation was found. An independent reference method to compare different CMR measurement methods is still lacking. In conclusion, CMR might play a major role in the evaluation of patients with TR by using 2D-indirect method indices such as RVol and RF for TR quantification and prognosis, but definitive outcome studies using 4D-direct method as a basis for treatment of TR are lacking but needed.</p>

摘要

In this systematic review, we aimed to analyze the methods and results of studies dedicated for quantifying tricuspid regurgitation (TR) with cardiac magnetic resonance (CMR), the concordance between echocardiography and CMR, the prognostic value and the reproducibility of CMR in patients with TR. Published studies on MEDLINE were included using search terms on TR and CMR until June 2024. Out of the 1108 screened articles, 19 studies fulfilled our inclusion criteria. The 2 most commonly used methods were the indirect method which uses 2D-phase contrast (2D-indirect) and the challenging measurement of right ventricular stroke volume. It was used in larger studies with higher proportion of patients with severe TR. The direct method, which uses 4D-phase contrast (4D-direct), has been mainly used in methodological studies with a low proportion of patients with severe TR. 4 studies comparing CMR with echocardiography showed poor severity agreement. In 6 studies assessing the prognostic value of CMR, TR evaluation with tricuspid regurgitant volume (RVol) or regurgitation fraction (RF) yielded a strong prognostic value although right ventricular ejection fraction was the most consistent prognostic predictor. There was very good inter-/intra-observer variability in 8 studies. No study with inter-examination evaluation was found. An independent reference method to compare different CMR measurement methods is still lacking. In conclusion, CMR might play a major role in the evaluation of patients with TR by using 2D-indirect method indices such as RVol and RF for TR quantification and prognosis, but definitive outcome studies using 4D-direct method as a basis for treatment of TR are lacking but needed.
