Valvular & structural heart disease
Characteristics and Outcomes of Patients with Atrial Versus Ventricular Secondary Tricuspid Regurgitation Undergoing Tricuspid Transcatheter Edge-to-Edge Repair – Results from the TriValve Registry
Authors' conclusion
In a real-world, multicentre registry, T-TEER was effective in reducing TR grade in both ASTR and VSTR. At 12-month follow-up, ASTR showed better survival than VSTR.
Study context
- Population
- Patients with secondary tricuspid regurgitation undergoing tricuspid transcatheter edge-to-edge repair, TriValve registry; primary tricuspid regurgitation (TR) and cardiac implantable electronic device excluded
- Participants
- 298 patients
- Exposure
- Atrial vs ventricular secondary TR undergoing tricuspid transcatheter edge-to-edge repair (T-TEER)
- Atrial STR (ASTR)n = 65
- Ventricular STR (VSTR)n = 233reference
- Outcome
- Procedural success and survival (key endpoints)
