Abstract
Aim: To determine the profiles of clinical features including four-limb blood pressure (BP), saturations of peripheral oxygen (SpO
2), and echocardiographic features in infants with coarctation of aorta (CoA) to facilitate congenital heart diseases screening.
Methods: The charts of infants with CoA were retrospectively reviewed. All in-hospital infants suspected of congenital heart diseases by clinical teams were prospectively measured of four limbs BPs and SpO
2 in a regional cardiac transferring center during 2013 and 2019. Echocardiography as a gold standard test was followed within 2 days after suspicion. All infants were divided into non-significant CoA group or significant CoA group based on the difference of BPs between right arm and lower limbs. Predictors of non-significant CoA were determined with multivariable logistic regression.
Results: One hundred thirty-three infants with CoA were identified. The BPs on upper limbs were higher than those on lower limbs (
P = 0.001). No statistical difference in SpO
2 was found between four limbs. Fifty-three (39.8%) infants presented with significant CoA. Thirty-four infants presented with low SpO
2 and 26 of 34 presented with non-significant CoA. Small ascending aorta diameter [0.070 (95% CI: 0.005–0.136),
P = 0.036] was an independent risk factors for non-significant CoA. Eighteen (13.5%) infants with CoA didn’t present with any of the BP difference, low SpO
2, murmur, or weak femoral pulse.
Conclusion: Less than half of the infants with CoA presented with a significant BP difference. Another one fifth presented with low SpO
2. Small ascending aorta diameter was an independent factor for non-significant CoA.
