摘要
During winter outbreaks of respiratory syncytial virus bronchiolitis from 2002 to 2004, three infants presented with a presumptive diagnosis of lower respirat ory tract infection and wheezing. The clinical condition in two cases was rapidl y progressive and precipitated into intractable shock; clinical and instrumental examinations revealed a cardiac origin of their illness. A subacute presentatio n permitted a cardiological assessment and a proper treatment in the third infan t. An abnormal origin of the left coronary artery from the pulmonary trunk was d emonstrated in all cases. The concurrent acute airway infection had a catastroph ic effect on the underlying cardiovascular anomaly leading to refractory cardiog enic shock and death. Conclusion:Admission chest X-ray film and arterial gas an alysis can raise the suspicion of cardiac involvement when treating a severe whe ezing episode in young infants. Paediatric cardiological evaluation with two-di mensional echocardiography may eventually reveal this rare condition, whereas ca rdiac catheterisation with aortography remains the standard means of diagnosis.
