Comparison of transcatheter leaflet-approximation and direct annuloplasty in tricuspid regurgitation

  Fig. 1. Preprocedural echocardiographic parameters. Comparison of preprocedural grade of TR, anteroseptal annulus diameter, coaptation gap and vena contracta measured by echocardiography. More patients in the annuloplasty group showed torrential TR (A). While annulus diameter was comparable in both groups (B), coaptation gap and vena contracta were significantly larger in the annuloplasty group (C, D). TR tricuspid regurgitation, TEER transcatheter edge to edge repair, AP direct annuloplasty

  Fig. 2. Comparison of TR reduction in total (A) and matched (B) cohort. Changes of TR from preprocedural to postprocedural comparing transcatheter edge to edge repair and direct annuloplasty is shown for total cohort (A) and the propensity-matched cohort (B). TR improved significantly in both groups (p < 0.001). While initially there were more advanced TR stages in annuloplasty group after intervention TR grades were similar (A). After matching initially TR grades were comparable and in the annuloplasty group an optimal reduction of TR grade to mild or none was significantly more common (26.1 vs. 47.8%, p = 0.031). (0 = none, I = mild, II = moderate, III = severe, IV = massive, V = torrential, TR = tricuspid regurgitation)

  Fig. 3. Comparison of NYHA functional class. For clinical outcome NYHA functional class of patients treated with transcatheter edge to edge repair and direct annuloplasty was compared at baseline and follow-up. Both treatment techniques significantly improved NYHA class, with a significantly more pronounced benefit in the annuloplasty group

  Fig. 4. Six months survival by treatment group. For mid-term outcome the survival of patients treated with transcatheter edge to edge repair and direct annuloplasty was examined with Kaplan–Meier analysis. There is no significant difference in survival comparing both treatment groups (p = 0.216)
