Methods: Between November 2018 and March 2021, the data of male COVID-19-negative patients (n=81; mean age: 65.5±8.5 years; range, 46 to 87 years) operated during the pandemic were compared with the data of male COVID-19-positive patients operated during the same period (n=14; mean age: 65.2±10.6 years). The number of patiets, demographic and perioperative data were compared between the patients operated during the pandemic (2020/2021 years; pandemic group) and the prepandemic period (2018/2019 years; control group).

Results: A statistically significant difference between the COVID-19-positive and COVID-19-negative patients was found in terms of the frequency of wound infection (n=3, 21.4% vs. n=12, 14.8%; p=0.013), resternotomy due to bleeding (n=2, 14.3% vs. n=0, 0%; p=0.018), and duration of hospitalization after surgery (26.4±20.4 days vs. 15.3±8.9 days; p=0.008). Comparing data of patients who had surgery before and during the pandemic, a significant decrease in the number of cardiac operations (166 vs. 95) was observed. There was significantly increased body mass index (p=0.01) and incidence of diabetes mellitus type 2 (p=0.021) in the pandemic group.

Conclusion: Despite a significantly higher rate of complications in patients infected with COVID-19, planned cardiac surgery with the utilization of adequate protective measures during quarantine is still a better option than a complete cessation of elective cardiac surgery.
