摘要

Aim: The Aortic Valve (AV) annular dimension with respect to the Body Surface Area (BSA) of the Indian population is compared against the standard values. Presence of discrepancies can lead to patient prosthesis mismatch during aortic valve replacement surgeries.Methods: This study was conducted on 406 subjects. AV diameter was examined by using parasternal long axis view, where the imaging plane transects the AV in an anteroposterior direction and its x axis is aligned parallel to the long axis of aorta. Data were statistically analysed with western population.Results: The AV dimension ranged from 12.2 mm to 21.2 mm in the BSA range of 0.6 to 1.9 m2, showing a linear increase in diameter with increasing BSA. There was an increase of about 2 mm, from 0.61 - 0.7 m2 BSA to 0.71 - 0.8 m2 BSA. A linear increase which ranged from 0.3 to 1 mm was observed for BSA which ranged from 0.81 m2 to 1.2 m2. In the BSA range of 1.21 ? 1.3 m2, there was an increase of 1.5 mm. A steady increase which ranged from 0.4?1 mm was observed in the BSA which ranged from 1.31- 1.9 m2.Conclusions: There is a significant difference between Indian and western population in the aortic dimension, in the body surface ranges of 0.61-0.7, 1.11-1.2, 1.21-1.3, 1.51-1.6, 1.61-1.7, 1.71-1.8 and 1.8-1.9 m2. In the range of 1.21-1.3 m2, the diameter was larger than standard, whereas in all the other ranges, AV diameter was smaller than standard values. BSA, as a good predictor of AV dimension, has also been proved.
