Impact of COVID-19 Pandemic in a Brazilian High-Volume Aortic Center

ABSTRACT

Abstract Introduction: The coronavirus disease 2019 (COVID-19) pandemic brought an unprecedented lack of control of what was to come. The intent of this document is to provide a balance of how much was ceased to be done for patients with aortic disease, to assess the mortality of these patients, and to show what happened to those who became COVID-19 positive during their hospitalization. Methods: From April 1st to July 31st 2020, the worst period of the pandemic in São Paulo, Brazil, the Institute's aortic surgical patients operated on were evaluated and those were compared with patients operated during the same period in 2019. Results: In 2019, 88 surgeries were performed; most of them were elective (66 [75%]), 10 were urgent, and 12 were emergency surgeries. In 2020, during the COVID-19 pandemic, we operated on only 31 patients, being 74.2% non-elective surgeries (P<0,001). There was a higher mortality for patients operated on during the pandemic surge of COVID-19 (P<0,001), but it was not specifically related to infected patients. Conclusion: The COVID-19 pandemic had an impact on surgical volume and outcome of patients with aortic disease, although it did not directly increase mortality.
