Vascular rings are malformations of the aortic arch in the main blood vessel that leads from the heart (aorta) that partly or completely encircle the windpipe (trachea) or the tube that leads from your mouth to your stomach (esophagus) or both. These defects are present at birth (congenital), but symptoms can occur either in infancy or later in life. Symptoms are caused by some portion of the ring pressing against the trachea or esophagus or both.

Vascular rings that press against the trachea and esophagus can lead to breathing and digestive problems. Respiratory signs and symptoms may include frequent respiratory infections, wheezing or coughing. Digestive signs and symptoms may include trouble swallowing, difficulty feeding or vomiting. Some people don't experience symptoms.

People with vascular rings may also have other congenital heart defects.
