OBJECTIVES: A large, prospective international registry was developed to evaluate the initial clinical applications of transcatheter tricuspid valve intervention (TTVI) with different devices. BACKGROUND: TTVI for native tricuspid valve dysfunction has been emerging during the last few years as an alternative therapeutic option to serve a large high-risk population of patients with severe symptomatic tricuspid regurgitation (TR). METHODS: The TriValve Registry included 312 high-risk patients with severe TR (76.4 ± 8.5 years of age; 57% female; EuroSCORE II 9 ± 8%) at 18 centers. Interventions included repair at the level of the leaflets (MitraClip, Abbott Vascular, Santa Clara, California; PASCAL Edwards Lifesciences, Irvine, California), annulus (Cardioband, Edwards Lifesciences; TriCinch, 4tech, Galway, Ireland; Trialign, Mitraling, Tewksbury, Massachusetts), or coaptation (FORMA, Edwards Lifesciences) and replacement (Caval Implants, NaviGate, NaviGate Cardiac Structures, Lake Forest, California). Clinical outcomes were prospectively determined during mid-term follow-up. RESULTS: A total of 108 patients (34.6%) had prior left heart valve intervention (84 surgical and 24 transcatheter, respectively). TR etiology was functional in 93%, and mean annular diameter was 46.9 ± 9 mm. In 75% of patients the regurgitant jet was central (vena contracta 1.1 ± 0.5; effective regurgitant orifice area 0.78 ± 0.6 cm2). Pre-procedural systolic pulmonary artery pressure was 41 ± 14.8 mm Hg. Implanted devices included: MitraClip in 210 cases, Trialign in 18 cases, TriCinch first generation in 14 cases, caval valve implantation in 30 cases, FORMA in 24 cases, Cardioband in 13 cases, NaviGate in 6 cases, and PASCAL in 1. In 64% of the cases, TTVI was performed as a stand-alone procedure. Procedural success (defined as the device successfully implanted and residual TR ≤2+) was 72.8%. Greater coaptation depth (odds ratio: 24.1; p = 0.002) was an independent predictor of reduced device success. Thirty-day mortality was 3.6% and was significantly lower among patients with procedural success (1.9% vs. 6.9%; p = 0.04); Actuarial survival at 1.5 years was 82.8 ± 4% and was significantly higher among patients who had procedural success achieved. CONCLUSIONS: TTVI is feasible with different technologies, has a reasonable overall procedural success rate, and is associated with low mortality and significant clinical improvement. Mid-term survival is favorable in this high-risk population. Greater coaptation depth is associated with reduced procedural success, which is an independent predictor of mortality.
