Conclusion:
According to our observations and dramatic higher in-hospital mortality of patients with COVID-19 who undergo cardiovascular surgery, we recommend to postpone all elective surgeries till the end of the crisis. In case of emergency indication for surgery, the patients should be tested for RT-PCR and chest CT scan before surgery and get necessary medications if highly suspected to COVID-19. In borderline surgical indications, especially in individuals with history of contact with any confirmed or suspected COVID-19 patients, we suggest to perform laboratory and imaging evaluations, wait for the screening results before the surgery and monitor the patients closely after the surgery. Meanwhile all health-care staffs who are involved in any procedures should use full personal protective equipment.
