A PE is a condition in which a blood clot lodges in the pulmonary artery, blocking blood flow to the lungs. Symptoms include:. A PE can occur when a blood clot forms in a vein such as in the legs and travels through the heart, eventually becoming lodged in a pulmonary artery.
Risk factors include blood clotting disorders, cancer , and prolonged physical immobility. A pulmonary embolism is a life-threatening medical emergency that must be treated with blood thinners or an interventional procedure.
Pulmonary arterial hypertension is a rare type of pulmonary hypertension characterized by narrowing, stiffening, and thickening of the arteries in and around the lungs. It can cause fatigue, shortness of breath, hemoptysis coughing up blood , and leg swelling. Pulmonary arterial hypertension can develop without a known reason, and risk factors include scleroderma or other connective tissue diseases, toxin exposure, and liver cirrhosis. The condition is progressive and may result in severe heart failure and disability due to intolerance of physical activity.
The pulmonary arteries carry blood from your heart to your lungs. These vessels are part of the pulmonary circulation, and they are affected by and have an effect on other blood vessels in this system. Congenital deformities of the heart can be associated with variations in the pulmonary arteries, and these issues may require surgical repair during childhood.

Two of the valves, the mitral and the tricuspid valves, move blood from the upper chambers of the heart the atria to the lower chambers of the heart the ventricles. The other two valves, the aortic and pulmonary valves, move blood to the lungs and the rest of the body through the ventricles.
When the heart valves open and close, they create sounds we know as our heartbeat. Here is an overview of circulation through the heart: First, blood returns from the body to the right atrium.
This blood has been depleted of oxygen when the oxygen was delivered to the body tissues, so it is seeking more oxygen to keep the process going.
The right atrium, now full of oxygen-depleted blood, pumps the blood through the tricuspid valve into the right ventricle. Then the right ventricle contracts to pump blood through the pulmonary valve into the pulmonary artery. The pulmonary artery brings blood away from the heart to the lungs where the blood receives the oxygen we breathe, becoming oxygen-rich blood. Treatment depends on the type and severity of pulmonary valve disease.

Overview Pulmonary valve disease is a condition in which the lung pulmonary valve — located between your heart's lower right chamber right ventricle and the artery that delivers blood to the lungs pulmonary artery — doesn't work properly.
