Key result
In an observational autopsy study of 210 hearts, 99.06% of aortic valves had three cusps, 52% showed fenestrations, 25.71% had asymmetrical cusps, and 10% had Lambl's excrescences.

Anatomical variations of the aortic valve, such as fenestrations and asymmetrical cusps, are common and have clinical relevance for valve diseases and surgeries.
No takes yet. Share an insight, caveat, or question.
Common aortic valve variants may inform imaging review before surgery; leaves open links to dysfunction or outcomes in prospective cohorts.
Ashalatha et al. (2017) conducted an observational in Aortic valve variations (n=210). Anatomical examination was evaluated on Number and morphology of aortic valve cusps. In an observational autopsy study of 210 hearts, 99.06% of aortic valves had three cusps, 52% showed fenestrations, 25.71% had asymmetrical cusps, and 10% had Lambl's excrescences.
