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)

Main finding

As reported in the abstract
