An unusual presentation of Cor-triatriatum as respiratory distress in adolescent male: A case report.

Cor triatriatum is a rare congenital heart disease (0.1% of all congenital cardiac defects). Most patients are identified shortly after birth with the evaluation of a distressed or cyanotic neonate. However, when the presentation is delayed, primary symptoms may mimic reactive airway disease. We present an 11-year-old adolescent male who presented with obstructive sleep apnea-like features initially, on further evaluation showed features of severe pneumonia. There was clinical and radiological dissociation with the findings. [ABSTRACT FROM AUTHOR]
