Imaging findings
Retrospectively gated cardiac CT angiography and cine imaging show a severely dilated ascending aorta and a unicuspid aortic valve, which was initially diagnosed as a bicuspid valve on echocardiography.
Key takeaways
A unicuspid aortic valve is the rarest congenital aortic valve anomaly, presenting similarly to a bicuspid valve but typically manifesting earlier in life with severe regurgitation or stenosis, often accompanied by ascending aortic aneurysm.
