What is a pulmonary artery sling? A pulmonary sling arises when the left pulmonary artery (LPA) arises anomalously from the posterior right pulmonary artery, creating an abnormal LPA course posterior to the trachea and anterior to the esophagus. This is associated with presence of complete cartilaginous tracheal rings and tracheomalacia, which are often associated with …
What is the importance of a right sided aortic arch? A right-sided arch may be associated with mirror-image branching, an aberrant left subclavian artery, or an isolated left subclavian artery. It may also be associated with tetralogy of Fallot or truncus arteriosus. If you see a right-sided aortic arch, look for other anomalies and consider …
