Respiratory syncytial virus in patients with congenital heart disease: a contemporary look at epidemiology and success of preoperative screening.

Awareness of respiratory syncytial virus (RSV) as a serious pathogen in the child with congenital heart disease is increasing. We studied the impact of RSV lower respiratory tract disease on patients in a large academic pediatric cardiology practice. We found that RSV disease necessitating hospitalization occurs in congenital heart disease patients well into the second year of life. Although pulmonary hypertension remains a significant risk factor for morbidity in these patients, it does not appear to be as much of a factor as in the past. By implementing a nasopharyngeal RSV enzyme-linked immunoassay screening of young patients prior to cardiac surgery we found a reduction in community-acquired postoperative RSV disease. We postulate this will lead to a reduction in nosocomial disease in the postoperative care unit.
