Median age was 37.5 years (IQR 26- 46, 60% females). The mean right
atrial volume indexed to body surface area (RAVI) was 19.5 ± 5.7
mL/m2 and the mean RALS was 32.7 ± 10.5%. There was a
trend towards decreasing RALS with age (r=-0.15, P=0.129) with no change
in RAVI with age ( P=0.27). Males had a tendency towards higher RAVI and
RALS measurements compared to females (20.8 ± 6.3
mL/m2 and 18.7 ± 5.2 mL/m2, P=0.07:
34.6 ± 9.6% and 31.4 ± 10.9 %, P=0.141, respectively) . BMI was an
independent predictor of RALS on multivariate analysis ( r= -0.43, P
=0.003)
