Abstract
A 68-year-old man presented following a cardiac arrest. Cardiopulmonary resuscitation was performed by the Lund University Cardiopulmonary Assist System (LUCAS), a mechanical chest compression device. Investigations revealed an aortic dissection, which was likely an iatrogenic injury from mechanical cardiopulmonary resuscitation by LUCAS. This case highlights this potential complication.
