ObjectiveTo analyze the perioperative outcomes of cardiac valve surgery in patients with asymptomatic SARS-CoV-2 infection. MethodsThe perioperative clinical data of patients receiving heart valve replacement in the Department of Cardiovascular Surgery, the First Affiliated Hospital of University of Science and Technology of China from November 2022 to February 2023 were retrospectively analyzed. According to whether the patients were infected with SARS-CoV-2, they were divided into a non-infected group and an asymptomatic group. The perioperative data of the patients were compared between the two groups, and the effect of asymptomatic infection on the result of heart valve replacement surgery was analyzed. ResultsA total of 66 patients were enrolled including 36 males and 30 females with a mean age of 58.0±11.1 years. There were 51 patients in the non-infected group and 15 patients in the asymtomatic group. There were 2 patients of mitral valve replacement, 20 patients of aortic valve replacement, 1 patient of double valve replacement, 3 patients of aortic valve replacement with tricuspid valvoplasty, 22 patients of mitral valve replacement and tricuspid valvoplasty, 18 patients of double valve replacement and tricuspid valvoplasty. Asymptomatic infected patients received more emergency surgery than uninfected patients (26.7% vs. 0.0%, P<0.01). There was no statistical difference in the duration of extracorporeal circulation, aortic occlusion, mechanical ventilation time after the surgery, ICU stay, postoperative drainage volume, or postoperative complications between the two groups. ConclusionPerioperative results of cardiac valve surgery in patients with asymptomatic SARS-CoV-2 infection and non-infection are almost the same.
