Although secondary TR is the most common pathology, some patients exhibit primary or predominantly primary TR. Characterization of patients with these pathologies in the T-TEER context has not been systematically performed.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and results<\/jats:title>\n                  <jats:p>Patients assigned to T-TEER by the interdisciplinary heart team were consecutively recruited in two European centres over 4 years. Echocardiographic images were evaluated to distinguish between primary and secondary causes of TR. Both groups were compared concerning procedural results. A total of 339 patients were recruited, 13% with primary TR and 87% with secondary TR. Patients with primary TR had a smaller right ventricle (basal diameter 45 vs. 49\u2005mm, P = 0.004), a better right ventricular function (fractional area change 45 vs. 41%, P = 0.001), a smaller right (28 vs. 34\u2005cm2, P = 0.021) and left (52 vs. 67\u2005mL\/m2, P = 0.038) atrium, and a better left ventricular ejection fraction (60 vs. 52%, P = 0.005). The severity of TR was similar in primary and secondary TR at baseline (TR vena contracta width pre-interventional 13 \u00b1 4 vs. 14 \u00b1 5\u2005mm, P = 0.19), and T-TEER significantly reduced TR in both groups (TR vena contracta width post-interventional 4 \u00b1 3 vs. 5 \u00b1 5\u2005mm, P = 0.10). These findings remained stable after propensity score matching. Complications were similar between both groups.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n
