Background: Mitral valve repair may lead to alterations of tricuspid regurgitation (TR).
Aims: We aimed to investigate alterations, predictors and prognostic relevance of TR evolution in a large-scale multicentre population of patients undergoing transcatheter mitral valve repair (TMVR) via the MitraClip.
Methods: In total, we included 531 TMVR patients with at least one available follow-up echocardiography. TR improvement was defined as a TR ≥II at baseline, which showed a decline of at least one TR categorisation.
Results: Distribution of preprocedural TR severity was TR 0/I 41% (220/531), TR II 39% (209/531) and TR ≥III 19% (102/531), respectively. Follow-up echocardiography was at 308±187 days. TR severity improved to TR 0/I 49% (259/531), TR II 35% (183/531) and TR III 17% (89/531), p=0.003. Out of 311 patients with TR ≥II at baseline, 41% (127/311) showed TR improvement. Atrial fibrillation (AF), residual mitral regurgitation ≥II (rMR) and tricuspid annular diameter (TAD) remained variables which prevented TR improvement (odds ratio 0.49 [0.29-0.84], 0.47 [0.27-0.81] and 0.97 [0.93-0.997], respectively). TR improvement was associated with better event-free survival regarding post-procedural heart failure hospitalisation (HHF) (hazard ratio 0.6 [0.38-0.94]). The main changes of TR severity occurred within 3 months post TMVR (p=0.006), while there were only minor TR changes between 3 and 12 months of follow-up (p=0.813).
Conclusions: TR improvement was frequent after TMVR. Predictors preventing TR improvement were AF, post-procedural rMR, and TAD. Furthermore, TR improvement was an early phenomenon occurring primarily within the first three months post TMVR and served as a suitable marker of reduced HHF.
