Patent Ductus Arteriosus: A heart defect in which a fetal structure remains open, causing excess blood flow through the lungs.
Pulmonary Hypertension: Increased blood pressure in the arteries supplying blood to the lungs; caused by increased resistance to blood flow in the lungs, usually a result of a lung disease.
Pulmonary Stenosis: Obstruction of the flow of blood from the heart to the lungs.
