CTICasesBicuspid Aortic Valve with Aortopathy
Imaging findings
Initial chest radiographs suggested significant ascending aortic dilatation, which was more evident on the lateral projection than the frontal view. CT confirmed a dilated ascending aorta, particularly involving its right lateral wall, in association with a bicuspid aortic valve displaying calcifications.
Key takeaways
Bicuspid aortic valve is commonly associated with aortopathy, presenting as ascending aortic dilatation. The pattern of dilatation, such as involving the right lateral wall, can correlate with specific bicuspid valve fusion patterns (e.g., right and left cusp fusion) and hemodynamics. Distinguishing between aortic root and ascending aortic dilatation (BAV root phenotype vs. others) has implications for genetic predisposition and surgical management.
