1. Patient presentation

  • A 28-year-old, otherwise healthy woman presented after having experienced acute pain in the left arm and chest at work.
  • Electrocardiography showed ST elevation in the inferior leads. In addition, blood troponin was elevated, leading to diagnosis of acute myocardial infarction.
  • Delayed enhancement MRI revealed a small myocardial infarction of the inferior wall of the left ventricle.
  • Conventional coronary angiography was normal, leading to the suspicion of an embolic cause of the infarction.
  • ECG-gated contrast-enhanced cardiac CT was performed for further exploration.
