Impact of COVID-19 on the Diagnosis of Coarctation of the Aorta in Infants.

Newborns with coarctation of the aorta are a potentially vulnerable population whose diagnosis could have been impacted by the COVID-19 pandemic. The objectives of this study were to assess if there was delayed diagnosis of infants with coarctation and if they had higher acuity prior to repair after the start of the pandemic. The Pediatric Health Information Systems database was queried for patients less than three months of age who underwent surgical repair or palliation of coarctation of the aorta. Patients were divided into three time periods: (1) pre-COVID (October 2017-December 2019), (2) early COVID (January 2020-December 2020), and (3) late COVID (January 2021-December 2021). The outcomes were age at repair and pre-procedure acuity. Among the 4885 patients, the median time to repair was 10 days during all time periods. Use of pre-procedure mechanical ventilation, vasopressors, and extracorporeal membranous oxygenation did not increase after the start of the pandemic. Median length of hospital stay increased after the start of the pandemic and did not return to baseline (22 days, 24 days, and 25 days, sequentially, p < 0.01). When analyzing patients who presented to the surgical hospital after 3 days of life, there were no differences in age at repair, pre-procedural acuity, or other outcomes. Age at repair of coarctation of the aorta and acuity did not change after the start of the COVID-19 pandemic. This suggests that the safeguards in place to ensure timely diagnosis of critical heart disease were adequate during this time of disruption.
