Key result
Aortic ostium angle α is inversely linked to helical flow patterns in the aorta.
Why the study?
The relationship between helical secondary flows in the aortic arch and aortic configuration in patients with atherosclerotic risks was not well understood.
Observational
Effect estimate: standardized coefficient -0.721
p-value: p=0.023
Finite element analysis demonstrates that aortic configuration, specifically the angle between the zero reference point and the aortic ostium, is independently associated with helical flow patterns in the aortic arch.
No takes yet. Share an insight, caveat, or question.
Aortic ostium angle may influence helical flow; hypothesis-generating and should not yet change practice or imaging protocols.
Lee et al. (2014) conducted an observational in Helical secondary flows in the aortic arch. Aortic configuration (Angle α) was evaluated on Helical flow pattern (standardized coefficient -0.721, p=0.023). Angle α between the zero reference point and the aortic ostium was independently associated with the helical flow pattern in the aorta (standardized coefficient -0.721, P=0.023).
