ObjectiveTo examine whether or not viral positive patients experienced worse outcomes and assess differences in surgical outcomes between viral-positive patients with and without viral symptoms within 30 days of surgery.MethodsThis retrospective study reviewed charts of pediatric patients who underwent congenital heart surgery and routine viral testing at a single institution over a consecutive 3-year period (2017-2019). Patients with a history of heart transplants, pacemaker changes, or implants, and mediastinal washouts were excluded from the study. Surgical outcomes were compared by viral status and viral symptoms, using the Fisher exact and Wilcoxon rank sum tests.ResultsAmong 1041 patients, 374 patients underwent routine preoperative viral testing, with 107 patients testing positive and 267 testing negative for viral swabs before surgery. There were no significant differences observed in surgical outcomes by viral status, including no differences in mortality. Among the 107 patients with positive viral swabs before surgery, comparisons between 24 patients with viral symptoms and 83 without symptoms within 30 days of surgery detected no significant differences in mortality or complication rates. However, symptomatic versus asymptomatic patients had significantly longer postoperative stay (23.4 vs 13.4 days; P = .02) and intubation time (9.8 vs 4.9 hours; P = .004).ConclusionsPatients who test positive before congenital heart surgery and are asymptomatic beyond the incubation period may proceed to surgery with no further delay. Patients who are viral positive and symptomatic have a longer postoperative stay and intubation time. A prospective study is needed to assess the importance of routine viral testing.Copyright © 2024 The American Association for Thoracic Surgery. Published by Elsevier Inc. All rights reserved.
