ABSTRACT
INTRODUCTION: The coronavirus disease 2019 (COVID-19) has negatively impacted healthcare services worldwide. We hypothesized that the pandemic would affect our case mix and mortality. Our objective was to study this impact. METHODS: We retrospectively studied all patients who underwent congenital heart surgeries from March 21st to August 21st in 2019 and 2020 using the institutional electronic database. We compared demographic data, preoperative and postoperative length of stay (LOS), risk stratification using Risk Adjustment for Congenital Heart Surgery (RACHS) classification and outcomes in both periods. RESULTS: We observed a 66.7% decrease in our surgical volume (285 × 95 patients). Patients operated in the pre-pandemic period were older (911.3 [174.8 - 5953.8] days-old) compared to the pandemic period (275 days-old; P<0.05). When the case mix was compared between periods, the percentage of neonatal surgery was increased in the pandemic era (8% × 21.1%; P<0.05), and the number of RACHS 1-2 surgeries decreased significantly (60.7 × 27.4%; P<0.05). Preoperative LOS was increased in the pandemic period (1.2 × 7 days; P=0.001). There was no significant increment in mortality (P=0.1). Two patients tested positive for COVID-19 in the postoperative period and both died. CONCLUSION: Our program observed a sudden decrease in surgical volume and a consequent increase in surgical complexity. There was a non-significant increment in mortality.

BACKGROUND AND AIM OF THE STUDY: This study analyzed the arrival of coronavirus disease 2019 (COVID-19) in Brazil and its impact on coronary artery bypass grafting (CABG) surgery. METHODS: Patients undergoing isolated CABG in six hospitals in Brazil were divided into two periods: pre-COVID-19 (March-May 2019, N = 468) and COVID-19 era (March-May 2020, N = 182). Perioperative data were included on a dedicated REDCap platform. Patients with clinical and tomographic criteria and/or PCR (+) for severe acute respiratory syndrome coronavirus 2 infection were considered COVID-19 (+). Logistic regression analysis was performed to create a multiple predictive model for mortality after CABG in COVID-19 era. RESULTS: Compared to 2019, in 2020, CABG surgeries had a 2.8-fold increased mortality risk (95% confidence interval [CI]: 1-7.6, p = .041), patients who evolved with COVID-19 had a 11-fold increased mortality risk (95% CI: 2.2-54.9, p < .003), rates of morbidities and readmission to the intensive care unit. The surgical volume was decreased by 60%. The model to predict mortality after CABG in the COVID-19 era was validated with good calibration (Hosmer-Lemeshow = 1.43) and discrimination (receiver operating characteristic = 0.78). CONCLUSION: The COVID-19 pandemic had an adverse impact on mortality, morbidity and volume of patients undergoing CABG.

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.

Since the beginning of the coronavirus disease (COVID-19) pandemic, in March 2020, the number of people infected with COVID-19 worldwide increases continuously. Brazil is being followed with great concern in the international media, as it can, very soon, be the epicenter of the pandemic. Initial surgical data suggest that patients who acquire COVID-19 in the perioperative period are prone to a higher morbidity and mortality, however, evidence in cardiac surgery is still scarce. This article aims to aggregate to the growing evidence suggesting that perioperative infection with severe acute respiratory syndrome coronavirus 2 contributes to a more morbid evolution of the case.
