Background: Atrial fibrillation (AF) is rare during pregnancy but the data on its impact during delivery is scaring. In this study, we aim to analyze the impact of AF in patients who underwent delivery via Cesarean section (CS), natural spontaneous delivery (NSD) or instrumental delivery (ID).

Methods: We obtained the data from the National Inpatient Sample from 2016-2020. Our primary outcome was in-hospital mortality. Secondary outcomes included length of stay, total hospital charges and respiratory failure requiring intubation. Primary and secondary outcomes were adjusted to variables that had a p-value<0.2 for that outcome. Results were considered statistically significant if p-value <0.05.

Results: There were 17,785,980 deliveries who underwent CS, NSD or ID. Of this, 6,000 patients had the secondary diagnosis of atrial fibrillation. The population had a mean age of 29.13 years. (See table 1) Patient with AF had almost twenty times more change of dying compared to those without AF odds ratio (OR) 19.12, 95% Confidence interval (CI) 4.33 - 84.45, p<0.001. Furthermore, AF cohort stayed for one and a half day longer Coefficient 1.55, CI 1.16 - 1.94, p<0.001, had a higher hospital charge Coefficient 19294.05, CI 14658.17 - 23929.93 and had a higher rate of respiratory complications requiring intubation OR 15.86, CI 7.83 - 32.15, p<0.001. (See table 2)

Conclusion: Atrial fibrillation has a substantial negative impact in inpatient outcomes on pregnant patients during delivery. Further research is needed to explore these disparities in maternal care.
