Serious Symptoms Of Pulmonary Artery Sling

Pulmonary artery sling is an uncommon congenital anomaly of the pulmonary arteries. In a healthy individual, the oxygen-poor blood from the body flows through the superior and inferior vena cava to the heart. This oxygen-poor blood moves through the right atrium to the right ventricle where it is then pumped through a split that ultimately forms the left and right pulmonary arteries. The left and right pulmonary arteries carry the oxygen-poor blood to the lungs to be reoxygenated. A healthy individual's pulmonary arteries sit in front of their windpipe and esophagus. However, individuals with pulmonary artery sling have a left pulmonary artery that branches from their right one.
