Background: Tricuspid regurgitation (TR) is prevalent and undertreated, with mortality and morbidity increasing with TR severity. Given poor outcomes with medical therapy and high in-hospital mortality for isolated tricuspid valve surgery, emerging transcatheter repair devices offer a promising alternative. Objectives: The Edwards Cardioband Tricuspid Valve Reconstruction System Early Feasibility study (NCT03382457) evaluates the treatment of functional TR via annular reduction with the Cardioband Tricuspid Valve Reconstruction System (Edwards Lifesciences). Methods: Patients with ≥ moderate functional TR were eligible for this prospective, single-arm multicenter study. At 1 year, patients were evaluated for echocardiographic parameters, clinical and quality-of-life measures, and major adverse events. Results: The 37 patients enrolled had a mean age of 78 years; 76% were female; and they had ≥ severe functional (97.3%) or mixed (2.7%) TR, atrial flutter/fibrillation (97%), and New York Heart Association functional class III/IV (65%). At 1 year, 73.0% achieved ≤ moderate TR (P < 0.0001), and 73.1% had ≥2 grade reductions. Echocardiography showed significant reductions in the tricuspid annulus diameter (P < 0.0001), mean vena contracta (P < 0.0001), proximal isovelocity surface area effective regurgitant orifice area (P < 0.0001), right ventricular end-diastolic diameter (P < 0.0001), and inferior vena contracta (P = 0.0006). New York Heart Association functional class improved significantly (P < 0.0001), with 92.3% achieving class I/II, and Kansas City Cardiomyopathy Questionnaire scores improved by 19.0 points (P < 0.0001). One-year cardiovascular mortality was 8.1%, reinterventions were necessary in 5.4%, major access site complications occurred in 8.1%, and severe bleeding was noted in 35.1% of patients. Kaplan-Meier estimates of survival and freedom from heart failure rehospitalization were 85.9% and 88.7%, respectively. Conclusions: One-year experience using the Cardioband system for tricuspid valve repair shows high survival and low rehospitalization rates with durable outcomes in TR reduction and echocardiographic, clinical, and quality-of-life outcomes.
