Background: A 43 year old woman presented with chest pain followed by cardiac arrest recovered after defibrillation. Coronary angiography revealed a narrowed anterior descending coronary artery but no intraluminal thrombi. Optic coherence tomography showed intramural hematoma and the patient was treated medically with aspirin, clopidogrel and atorvastatin. Two weeks later the pain recurred and coronary angiography revealed similar findings. After medical treatment with heparin followed by aspirin and clopidogrel she has remained stable.
