Intractable Coronary Spasm Requiring Percutaneous Coronary Intervention after Coronary Artery Bypass Grafting in a Patient with Moyamoya Disease

  • 1Department of Thoracic and Cardiovascular Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea


Moyamoya disease (MMD) is characterized by progressive steno-occlusive lesions of the distal or proximal branch of the internal carotid arteries, and cerebrovascular symptoms are its major complications. Extracranial vascular involvement including the coronary artery has been reported, and some case reports have described variant angina or myocardial infarction. However, no report has yet described a case of myocardial infarction after coronary artery bypass grafting (CABG). Here, we present a patient with MMD who suffered cardiac arrest caused by myocardial infarction due to a coronary spasm after offpump CABG and who was discharged successfully after treatment with a veno-arterial extracorporeal membrane oxygenator and percutaneous coronary intervention.
