We analyzed aortic valves in 70 anonymized coronary computed tomography
angiograms. Mean patient age was 53 ± 11 years. All aortic valves were
tricuspid, without calcifications and aortic roots were of normal
dimensions. Asymmetry of the three leaflets in individual patients was
assessed by calculating absolute and relative differences between the
largest and the smallest of the three leaflets.
