In brief: Rare CHD

A rare congenital heart defect.
The pulmonary valve doesn’t form and not enough blood can flow to the lungs to get oxygen; only through the PDA (patent ductus arteriosus). It often occurs as part of a condition called tetralogy of fallot. There is usually a hole between the left and right ventricles of the heart (ventricular septal defect). Surgery as a newborn is required.

In brief: Absent/ never formed

The defect occurs when an unopen artery without a valve cannot carry blood to the lungs.
This is ok during pregnancy since fetal lungs don't need to receive blood & add o2.Blood is pumped thru bypass circuits to the body.After birth, when lungs must supply o2, this can be a fatal defect.If recognized early, drs can keep the bypass open & heart surgeons can reroute the flow with open heart surgery.
