  • CONCLUSIONS: The CTarea, which demonstrated the optimal approach to annulus sizing and prosthesis choice of BAVs with high eccentricity, should be included into the BAV-specific annulus sizing recommendation. The insufficiency of CTperi lay in overestimation of surgical or TAVR valve selections. Good agreement of 3DTEE sizing proved its superiority in annulus sizing for BAVs unsuitable for CT, but it should be used with caution for patients with a calcified annulus, where partial acoustic shadowing could lead to image inaccuracy.• The area-derived perimeter by CT is the optimal approach to annulus sizing of BAVs. • The perimeter-derived approach is prone to overestimation of BAVs. • 3DTEE showed its superiority in annulus sizing for BAVs unsuitable for CT, but it should be used with caution in patients with a calcified annulus.
