Figure 2: Gated CT coronary angiography.
(a) CT axial reconstruction demonstrating apparent trileaflet morphology
of the AV.
(b) Axial reconstruction perpendicular to centerline through the aortic
root, demonstrating root dilatation and asymmetrical prominence of the
left coronary sinus.
(c) Longitudinal reconstruction through the aortic root confirming
asymmetrical root dilatation with increased RCC-LCC diameter (maximum
45mm).

supraannular aortic intimal tear above the RCC/NCC commissure. (b)
Excised supraannular aortic root intimal defect.
