Sense of Impending Doom: Cardiac Arrest Due to Anomalous Left Coronary Artery From the Right Pulmonary Artery.

A 19-year-old female athlete with a history of anxiety and anorexia nervosa (binge-purge and overexercise, in remission) experienced escalating health-focused anxiety preceding cardiorespiratory collapse during exercise. Imaging revealed an anomalous left coronary artery originating from the right pulmonary artery, a rare variant of a typically fatal congenital anomaly. Extensive collateral circulation allowed survival until successful surgical repair, with subsequent full recovery.
