A young Japanese woman who appeared to be free from any coronary risk factors was admitted to a local hospital with chest pain. Serological tests showed no evidence of inflammation; however, an electrocardiogram revealed diffuse myocardial ischemia and a coronary angiogram demonstrated isolated bilateral coronary ostial stenoses. Moreover, her serum creatine phosphokinase level was high. On the day following admission, the patient developed severe cardiogenic shock, and she was transferred to our hospital where emergency coronary artery bypass grafting with the saphenous veins was performed using retrograde tepid blood cardioplegia. Recovery of cardiac function was immediate and her postoperative course was uneventful. We suspect that fibromuscular dysplasia was the most likely cause of the ostial stenoses in this patient.
