CTICasesBicuspid Aortopathy
Imaging findings
Cardiac CTA demonstrates a calcified bicuspid aortic valve. In addition, there is moderate-to-severe dilatation of the ascending aorta (4.8 cm) predominantly involving the right lateral wall, consistent with the right-left cusp fusion pattern of bicuspid aortopathy. The aortic root and distal arch are relatively spared.
Key takeaways
Bicuspid aortopathy is a common cardiovascular manifestation of bicuspid aortic valve disease, characterized by progressive dilatation of the ascending aorta. The pattern of dilatation is determined by the specific cusp fusion type: right-left cusp fusion typically causes dilatation of the ascending aorta along its right lateral margin due to eccentric flow jets, whereas right-non coronary cusp fusion involves the arch and root, requiring precise reporting for surgical planning.
