Authors' conclusion

Patients previously deemed TEER unsuitable can be safely and effectively treated with the mitral TEER fourth-generation device.

Study context

Population
Patients with mitral regurgitation (MR) treated with the MitraClip G4 System
Participants
1,164 patients
Comparison
TEER outcomes across HVC TEER-suitability categories
  • Risk of stenosis (RoS)n = 56
  • RoIRn = 54
  • MMRn = 326
  • TEER-suitable (TS)n = 303reference
