Cardiovascular surgery during the first wave of COVID-19 pandemic

Background: In this study, we aimed to evaluate primary outcomes and main characteristics of emergency and elective/urgent cardiovascular surgeries which were performed in the first three months of the novel coronavirus disease 2019 (COVID-19) pandemic in our center. Methods: Between March 11th, 2020 and June 11th, 2020, a total of 209 patients (44 males, 165 females; mean age: 57.3±12.8 years; range, 20 to 80 years) who underwent emergency or elective/urgent surgery with cardiovascular pathologies were retrospectively analyzed. The patients were classified as emergency and elective/urgent according to the level of necessity of the surgical procedure at the time of hospital admission. Pre-, intra-, and postoperative data of the patients were recorded. Results: During the study period, 156 elective/urgent and 74 emergency cardiovascular surgeries were performed. Six COVID-19 (+) patients were operated emergently. The number of acute aortic dissection and peripheral vascular surgery was higher in the emergency group (p<0.05). Two patients who were COVID-19 (–) preoperatively became COVID-19 (+) in the postoperative period. In these patients, acute respiratory distress syndrome developed, and extracorporeal membrane oxygenation support was needed. Four patients who needed post-cardiotomy extracorporeal membrane oxygenation support due to low cardiac output were COVID-19 (–) both in the pre and postoperative periods. The overall in-hospital mortality rate was 9.1%. Conclusion: Even during pandemic such as COVID-19, referral centers with experienced personnel can provide non-pandemic healthcare with a quality close to the daily routine.
