Respiratory syncytial viral infection in an infant with unrepaired anomalous left coronary artery from the pulmonary artery

Abnormal origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare coronary anomaly in children that requires necessary and urgent repair. We report a child who was hospitalized with respiratory failure due respiratory syncytial viral (RSV) infection and was subsequently diagnosed with ALCAPA. Aggressive treatment for RSV included synagis and nebulized ribavirin prior to surgical repair. After waiting 4 weeks for the RSV infection to resolve, she underwent successful left coronary artery reimplantation on hospital day 27 and has regained normal left ventricular size and function.
