INTRODUCTION AND OBJECTIVES: In patients with tricuspid regurgitation (TR), edge-to-edge transcatheter tricuspid valve repair (TTVR) is the strategy with the highest penetration worldwide. A dedicated edge-to-edge TTVR system has recently become available in Europe. The present study describes the initial experience with the system in Spain.
METHODS: This multicenter study collected individual data from the centers accepted for the use of the novel system within an initial limited release. Between June 2020 and March 2021, all patients undergoing an edge-to-edge TTVR using the TriClip system in Spain were included in the study. The primary endpoint was the achievement of a TR reduction of at least 1 grade at discharge.
RESULTS: We included 34 patients. Most of them reported a previous history of atrial fibrillation (91%) and only 1 had a pacemaker lead. The primary endpoint (TR reduction of at least 1 grade at discharge) was met in all patients. Most of the patients required 1 (47%) or 2 clips (44%) with a clear predominance of XT (87%) over NT (13%). The location of the first clip was anteroseptal in >90% of the patients. Only 1 patient had a partial detachment, which was stabilized with additional clips in the same procedure. At discharge, TR severity was≤2 in 91% of patients. At 3 months, mortality was nil. Overall, 88% of patients were in New York Heart Association functional class≤2 and 80% had residual TR≤2.
CONCLUSIONS: Edge-to-edge TTVR seemed to be effective and safe with a sustained TR reduction at 3 months. Further studies will be needed to confirm our findings.
