The basal aortic root measurements were determined in
320 fresh, autopsied, normal, adult, Sri Lankan hearts
collected from the Judicial Medical Office, National
Hospital of Sri Lanka. The correlation between the
measurements and demographic data of the individual
was calculated. The mean aortic root circumference at
the basal ring was 64.7 mm ± 7SD (males 66.0mm ±
6.4SD, females 58.0mm ± 6.1SD) and calculated aortic
annular diameter was 20.60mm + 2.2SD (males 21,02mm
±2.0SD, females 18.47mm ± 1.9SD). Mean circumference
showed significant gender difference. Significant positive
correlation was seen between the age and aortic root
circumference. We describe the normal range of aortic
root diameters in healthy adult autopsied Sri Lankans.
The values are smaller in Sri Lankans compared to
Caucasians.
