Isolated absent pulmonary valve with intact ventricular septum in a young child: A rare case report.

Absent pulmonary valve syndrome, commonly linked with tetralogy of Fallot and ventricular septal defect, is a rare congenital condition. It is exceedingly rare to have an isolated absent pulmonary valve with an intact ventricular septum without cardiovascular shunt lesions, such as an atrial/ventricular septal defect or patent ductus arteriosus. This report presents a case of such rarity involving a young child with recurrent lower respiratory tract infections.
