Abstract

A 47-year-old man sustained multisystem injuries after being struck by a vehicle travelling at high speeds. Shortly after admission to the emergency department he suffered a ventricular tachycardia/ventricular fibrillation cardiac arrest lasting 30 min. Investigations following return of spontaneous circulation raised suspicion for an anterolateral ST-elevation myocardial infarction. Despite his major traumatic injuries the patient was transferred for percutaneous coronary intervention uncovering a complete thrombosis of the ostium of the left anterior descending artery. Immediately following coronary revascularisation, the patient developed cardiogenic shock resulting in a multidisciplinary decision to place the patient on veno-arterial extracorporeal membrane oxygenation (VA-ECMO). The management of cardiogenic shock due to acute myocardial infarction with VA-ECMO and multiple traumatic injuries were often at odds with each other, resulting in a series of challenging decisions on timing of surgery and anticoagulation. The patient was liberated from VA-ECMO after 72 hours and continues rehabilitation in hospital.
