Abstract
An athletic man in his 40s was brought in to the emergency department by ambulance following a brief episode of central chest pain and dizziness five miles in to a ten mile stationary bike ride. Observations were normal at the scene and there were no ECG changes but he appeared unwell. Further assessment revealed no palpable right radial or brachial pulses and he complained of a severe right frontal headache. CT of the aorta showed an extensive type A dissection with a significantly dilated aortic root. Following emergency cardiothoracic surgery, he was found to have suffered cerebral hypoxia and died.
