Fig. 2From: Dynamic changes of mitral valve annulus geometry at preprocedural CT: relationship with functional classes of regurgitationD-shaped segmentation of mitral annulus on cardiac computed tomography angiography (CCTA). Traced in blue is the trigone-to-trigone diameter, in yellow the septal-to-lateral diameter, in orange the intercommissural diameter, and the dashed light blue line plus the trigone-to-trigone diameter depict the mitral annulusBack to article page
