Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study will evaluate the use of TAVR (Transcatheter Aortic Valve Replacement), which is a minimally invasive procedure designed to replace the aortic valve inside the heart. The devices that will be used include the Edwards 12F Sheath Introducer Set, a hollow, flexible tube used to facilitate insertion of devices into the vasculature, and the SAPIEN X4 Transcatheter Heart Valve, an artificial heart valve that is made to replace the diseased aortic heart valve. The TAVR procedure will be performed by an experienced heart surgeon and/or cardiologist in the hospital under local or general anaesthesia. The SAPIEN X4 valve will remain in the body following the procedure but the 12F Sheath is removed at the end of the procedure.

Can healthy volunteers participate?
No
Key exclusion criteria
1. Anatomical characteristics that would preclude safe femoral placement of the introducer sheath or safe passage of the delivery system

18. Stroke, transient ischemic attack or neurological signs and symptoms attributed to carotid or vertebrobasilar disease within 90 days prior to the study procedure
19. Hemodynamic or respiratory instability requiring inotropic or mechanical support within 30 days prior to the study procedure
20. Renal insufficiency and/or renal replacement therapy
21. Leukopenia, anaemia, thrombocytopenia
22. Inability to tolerate or condition precluding treatment with antithrombotic therapy

26. BMI greater than 50 kg/m2
27. Estimated life expectancy less than 24 months
28. Female who is pregnant or lactating
29. Active SARS-CoV-2 infection
30. Participating in another investigational drug or device study that has not reached its primary endpoint
31. Subject considered to be part of a vulnerable population
