A multicentre roadmap to restart elective cardiac surgery after COVID-19 peak in an Italian epicenter.

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.
