An infant with respiratory distress

Infants with previously undiagnosed cardiac conditions may present to the emergency department with nonspecific signs and respiratory symptoms. These patients may be erroneously diagnosed as having bronchiolitis. We report a 2-month-old female infant who presented with respiratory distress and showed no improvement with nebulized albuterol treatment. This infant was found to have anomalous origin of the left coronary artery from the pulmonary artery.
