Background!#!Transcatheter tricuspid valve repair (TTVR) is a promising technique for the treatment of tricuspid regurgitation (TR). Data comparing the performance of novel edge-to-edge devices (PASCAL and MitraClip-XTR) are scarce.!##!Methods!#!We identified 80 consecutive patients who underwent TTVR using either the PASCAL or MitraClip-XTR system to treat symptomatic TR from July 2018 to June 2020. To adjust for baseline imbalances, we performed a propensity score (PS) 1:1 matching. The primary endpoint was a reduction in TR severity by at least one grade at 30 days.!##!Results!#!The PS-matched cohort (n = 44) was at high-surgical risk (EuroSCORE II: 7.5% [interquartile range (IQR) 4.8-12.1%]) with a mean TR grade of 4.3 ± 0.8 and median coaptation gap of 6.2 mm [IQR 3.2-9.1 mm]. The primary endpoint was similarly observed in both groups (PASCAL: 91% vs. MitraClip-XTR: 96%). Multiple device implantation was the most common form (59% vs. 82%, p = 0.19), and the occurrence of SLDA was comparable between the PASCAL and MitraClip-XTR system (5.7% [2 of 35 implanted devices] vs. 4.4% [2 of 45 implanted devices], p = 0.99). No periprocedural death or conversions to surgery occurred, and 30-day mortality (5.0% vs. 5.0%, log-rank p = 0.99) and 3-month mortality (10.0% vs. 5.0%, log-rank p = 0.56) were similar between both groups. During follow-up, functional NYHA class, 6-min walking distance, and health status improved in both groups.!##!Conclusions!#!Both TTVR devices, PASCAL and MitraClip-XTR, appeared feasible and comparable for an effective TR reduction. Randomized head-to-head comparisons will help to further define the appropriate scope of application of each system.
