Abstract Background Both coronavirus disease (COVID‐19) and cardiac surgery have a negative impact on pulmonary function. This study aimed to determine the postoperative respiratory outcomes of patients with COVID‐19 who underwent cardiac surgery. Methods In this retrospective study, we reviewed and analyzed the patient characteristics and clinical data of 25 asymptomatic patients with COVID‐19 who underwent urgent or emergency cardiac surgery at Tehran Heart Center Hospital, Iran, between 29 February and 10 April 2020. Results The mean age, EuroSCORE, and body mass index were 57.3 ± 15.1 years, 6.65 ± 1.29, and 25.7 ± 3.7 kg/m 2 , respectively. Four patients underwent off‐pump cardiac surgery and 21 underwent on‐pump cardiac surgery with a median cardiopulmonary bypass time of 85 minutes (interquartile range (IQR, 50‐147). The overall mortality rate and the length of stay in the intensive care unit (ICU) were higher compared to those of a propensity‐matched group of patients who underwent cardiac surgery in the pre‐COVID era. The median intubation time was 13 hours (IQR, 9.5‐18), which was comparable to that of pre‐COVID cardiac surgery patients. The readmission rate to the ICU was 16%. In this ICU readmitted group, the mean oxygen index, FiO 2 , and mortality rate were higher and the PaO 2 /FiO 2 ratio was lower than those of the nonreadmitted patients. Conclusions Although early respiratory outcomes of asymptomatic COVID‐19 patients who underwent early cardiac surgery appeared to be satisfactory, compared to the propensity‐scored matched non‐COVID group, the postoperative outcomes were worse, especially in the ICU readmitted patients. We suggest postponing cardiac operations unless the patient requires emergency surgery.
