Two cardiovascular anomalies reconstructed from findings in a 57 y.o. female caucasian cadaver whose death was determined as non-cardiovascular. She presents with a circumflex retroesophageal right aortic arch (CReRAA) that gives rise to an aberrant left subclavian artery from a diverticulum of the proximal descending aorta. The left ligamentum arteriosum completes a vascular ring with the CReRAA around her trachea and esophagus. She also presents with persistent left superior vena cava (PLSVC) amid regular right superior vena cava (SVC) (i.e., double SVC) with an innominate vein briding the two. Her PLSVC leads to a dialated coronary sinus coursing to the posterior left coronry sulcus to the right atrium. Ethan Snow, PhD. UNMC, Department of Genetics, Cell Biology and Anatomy; Omaha, NE.
