Fig 1 Schematic drawing of the aorta and measured variables to obtain the geometric pattern of the ascending aorta, aortic arch, and aortic isthmus. The horizontal arrow represents the span of the aortic arch base. The radius of the greater and lesser curvature are indicated. (L = aortic arch base length; R1 = radius of the greater curvature; R2 = radius of the lesser curvature.)
