Aortopulmonary window: a case report.

Aortopulmonary window (A-P window) is a rare congenital heart disease. The majority of patients come to the hospital with congestive heart failure. If they are left untreated, irreversible pulmonary vascular hypertension inevitably occurs. Although the hemodynamic of this disease resembles large persistent ductus arteriosus, the treatment is quite different. We report one patient of A-P window, a 4 month-old girl, who presented with fever and dyspnea. On investigations, she had A-P window. We successfully treated her by closure the defect under cardiopulmonary bypass. We describe the technique we used.
