Background: Aortic root dimension varies on the basis of age, body surface area, ethnicity, and in pathological states such as bicuspid aortic valve and connective tissue disorders. Aim: This observational study has been done to determine aortic root dimension in normal Indian population. In this study, aortic root dimensions were measured by two-dimensional (2D) echocardiography in parasternal long axis (PLAX) view by inner edge to inner edge method. Materials and Methods: Clinically normal Indian population was prospectively recruited. All participants were asymptomatic. All echocardiographic measurements were done twice and image acquired by single observer on the same machine. Aortic root dimensions measurements were done with 2D echo in PLAX view at 4-level aortic annulus, sinus of Valsalva, sinotubular junction, and proximal ascending aorta. Results: Aortic annulus does not show any significant correlation with age. Age parameter shows a significant correlation with the ascending aorta and sinus, sino-tubular (ST) junction. Weight parameter shows a significant correlation with annulus, sinus, and ST junction. Height parameter shows a significant correlation with all aortic dimensions. Conclusion: Indian patient has different body surface area than the Western population; therefore, there is a need of standard normal aortogram dimension for normal Indian population.
