The International Multicenter TriValve Registry: Which Patients Are Undergoing Transcatheter Tricuspid Repair?

This study sought to develop a large, international registry to evaluate the diffusion of these approaches and investigate patient characteristics and initial clinical results. Several transcatheter tricuspid valve therapies are emerging as therapeutic options for patients with severe symptomatic tricuspid regurgitation (TR), generally a high-risk surgical population. The TriValve (Transcatheter Tricuspid Valve Therapies) registry included 106 high-risk patients (76 ± 9 years of age; 60.4% women; European System for Cardiac Operative Risk Evaluation II 7.6 ± 5.7%) from 11 cardiac centers, with severe TR. A total of 35% of the patients had prior left heart valve intervention (surgical in 29 of 106 and transcatheter in 8 of 106 patients).
