N Engl J MedPublished

  • Randomised controlled trial
  • multicentre
  • 33 UK centres

Authors' conclusion

Among participants undergoing TAVI, routine use of CEP did not decrease the incidence of stroke within 72 hours.

Study context

Population
Patients with AS undergoing transcatheter aortic-valve implantation (TAVI), UK
Participants
7,635 patients
Comparison
TAVI with cerebral embolic protection (CEP) device vs TAVI without CEP device
  • CEPn = 3,815
  • Controln = 3,820reference
Primary endpoint
Stroke
Follow-up
Within 72 hours after TAVI or before discharge (if sooner)
