ABSTRACT
OBJECTIVE: To analyze Italian Cardiac Surgery experience during the pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) identifying risk factors for overall mortality according to coronavirus disease 2019 (COVID-19) status. METHODS: From February 20 to May 31, 2020, 1354 consecutive adult patients underwent cardiac surgery at 22 Italian Centers; 589 (43.5%), patients came from the red zone. Based on COVID-19 status, 1306 (96.5%) were negative to SARS-CoV-2 (COVID-N), and 48 (3.5%) were positive to SARS-CoV-2 (COVID-P); among the COVID-P 11 (22.9%) and 37 (77.1%) become positive, before and after surgery, respectively. Surgical procedures were as follows: 396 (29.2%) isolated coronary artery bypass grafting (CABG), 714 (52.7%) isolated non-CABG procedures, 207 (15.3%) two associate procedures, and three or more procedures in 37 (2.7%). Heart failure was significantly predominant in group COVID-N (10.4% vs. 2.5%, p = .01). RESULTS: Overall in-hospital mortality was 1.6% (22 cases), being significantly higher in COVID-P group (10 cases, 20.8% vs. 12, 0.9%, p < .001). Multivariable analysis identified COVID-P condition as a predictor of in-hospital mortality together with emergency status. In the COVID-P subgroup, the multivariable analysis identified increasing age and low oxygen saturation at admission as risk factors for in-hospital mortality. CONCLUSION: As expected, SARS-CoV-2 infection, either before or soon after cardiac surgery significantly increases in-hospital mortality. Moreover, among COVID-19-positive patients, older age and poor oxygenation upon admission seem to be associated with worse outcomes.

BACKGROUND: During the Italian Phase-2 of the coronavirus pandemic, it was possible to restart elective surgeries. Because hospitals were still burdened with coronavirus disease 2019 (COVID-19) patients, it was focal to design a separate "clean path" for the surgical candidates and determine the possible effects of major surgery on previously infected patients. METHODS: From May to July 2020 (postpandemic peak), 259 consecutive patients were scheduled for elective cardiac surgery in three different centers. Our original roadmap with four screening steps included: a short item questionnaire (STEP-1), nasopharyngeal swab (NP) (STEP-2), computed tomography (CT)-scan using COVID-19 reporting and data system (CO-RADS) scoring (STEP-3), and final NP swab before discharge (STEP-4). RESULTS: Two patients (0.8%) resulted positive at STEP-2: one patient was discharged home for quarantine, the other performed a CT-scan (CO-RADS: <2), and underwent surgery for unstable angina. Chest-CT was positive in 6.3% (15/237) with mean CO-RADS of 2.93 ± 0.8. Mild-moderate lung inflammation (CO-RADS: 2-4) did not delay surgery. Perioperative mortality was 1.15% (3/259), and cumulative incidence of pulmonary complications was 14.6%. At multivariable analysis, only age and cardiopulmonary bypass (CPB) time were independently related to pulmonary complications composite outcome (age >75 years: odds ratio [OR]: 2.6; 95% confidence interval [CI]: 1.25-5.57; p = 0.011; CPB >90 min. OR: 4.3; 95% CI: 1.84-10.16; p = 0.001). At 30 days, no periprocedural contagion and rehospitalization for COVID-19 infections were reported. CONCLUSIONS: Our structured roadmap supports the safe restarting of an elective cardiac surgery list after a peak of a still ongoing COVID-19 pandemic in an epicenter area. Mild to moderate CT residuals of coronavirus pneumonia do not justify elective cardiac surgery procrastination.
