ABSTRACT
Background: We evaluated our early experience of cardiac procedures in children with congenital heart defects (CHD) after asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, to understand whether recent reverse transcription-polymerase chain reaction (RT-PCR) positivity had a negative impact on their postprocedural recovery and outcomes. Materials and Methods: In this retrospective observational study, all patients with CHD who underwent cardiac surgery or transcatheter intervention at our institution between March 2020 and June 2021 who were detected to have asymptomatic SARS-CoV-2 infection on routine RT-PCR were included. Details of the cardiac procedure and postprocedural recovery were reviewed and compared with RT-PCR-negative patients who concurrently underwent similar cardiac surgeries or interventions at our center. Results: Thirteen patients underwent cardiac surgery after recent SARS-CoV-2 positivity after a mean interval of 25.4 ± 12.9 days. One patient expired with multiorgan dysfunction and systemic inflammatory response with elevated D-dimer, serum Ferritin, C-reactive protein, and significant ground-glass opacities on chest radiograph. Another patient developed spontaneous thrombosis of the infrarenal abdominal aorta, bilateral iliac arteries, and bilateral femoral veins, requiring low-molecular weight heparin postoperatively. This patient's postoperative recovery was also prolonged due to lung changes delaying extubation. All other patients had uneventful postprocedural recovery with intensive care unit and hospital stays comparable to non-SARS-CoV-2-infected patients. Conclusions: From our early experience, we can surmise that an interval of 2-3 weeks after asymptomatic SARS-CoV-2 infection is adequate to undertake elective or semi-elective pediatric cardiac surgeries. For patients requiring emergent cardiac surgery prior to this interval, there is potentially increased risk of inflammatory and/or thrombotic complications.
