One hundred normal Indian subjects were studied to establish the normal left atrial dimension (LAD), left atrial dimension corrected to body surface area (LA index) and left atrium to aorta ratio (LA/AO) for this population. Normal mean LAD was 21.9 ± 3.6 mm (12 mm to 30 mm). Elderly subjects had higher mean LAD (25.2 ± 3.6 mm). The LA index for adults was 14.1 ± 2.5 mm. LA index for younger subjects was higher because of low body surface area. Mean LA/AO was 0.95± 0.22;LA/AO greater than 1.17 is suggested as a criterion for LA enlargement.
