- Native aortic annulus size unsuitable for the THV

-
Anatomical characteristics that would preclude safe placement of the introducer sheath or safe passage of the delivery system
|
-
Aortic valve is unicuspid or non-calcified
|
-
Bicuspid aortic valve with an aneurysmal ascending aorta > 4.5 cm or severe raphe/leaflet calcification
|
-
Pre-existing mechanical or bioprosthetic aortic valve
|
-
Severe aortic regurgitation
|
-
Prior balloon aortic valvuloplasty to treat severe AS
|
|
-
Left ventricular outflow tract calcification that would increase the risk of annular rupture or significant paravalvular leak post-TAVR
|
-
Cardiac imaging evidence of intracardiac mass, thrombus, or vegetation
|
-
Coronary or aortic valve anatomy that increases the risk of coronary artery obstruction post-TAVR
