In brief: Congenital defect

Pa involves the valve, which is imperforate, and makes blood flow to the lungs dependent on other sources.
If combined with a ventricular septal defect it can be repaired in most cases. If no vsd exists the right chamber is most often underdeveloped and repair is more complex. You should seek advice from your cardiologist who knows the details about your (childs) anatomy.
