Real-World Experience in Tricuspid Transcatheter Edge-to-Edge Repair: Transcatheter Tricuspid Valve Repair in Spain Registry

Significant tricuspid regurgitation (TR) is associated with increased morbidity and mortality. The development of transcatheter valve repair therapies has opened a wide range of opportunities for treatment of patients with high surgical risk. Real-world data might improve patient selection and outcome. The authors sought to investigate acute and short-term cardiovascular outcomes of tricuspid transcatheter edge-to-edge repair (T-TEER) with dedicated devices in a real-world setting. This is a retrospective, single-arm, multicenter registry conducted at 15 sites in Spain. The primary end point was a composite of all-cause death, rehospitalization for heart failure, and tricuspid valve re-intervention. Patients included (n=283) were older (76±9 years, 70% female), and showed significant comorbidities. Massive or torrential TR was present in 55% of subjects, with secondary cause being the main mechanism of regurgitation in ≈80% of individuals. Intraprocedural success was achieved in 79% of patients. At 1-year follow-up, significant improvements in TR grade (≥3+, 100% to 25%,
