An 87-year-old male with old myocardial infarction was referred to the hospital due to left femur neck fracture and intermittent dizziness. Significant 2:1 atrioventricular block was demonstrated on initial electrocardiogram (Figure 1). Transthoracic echocardiography showed reduced left ventricular function (LVEF = 47%) with regional wall motion abnormality of right coronary artery (RCA) and left circumflex coronary artery (LCx) artery. Coronary angiography showed patent previous proximal RCA and distal LCx stents. Temporary pacemaker was inserted initially and the patient was planned for permanent pacemaker insertion after the surgery.

Simultaneous thrombosis affecting more than one coronary artery has been reported to occur in about 4.8% of the cases at the time primary percutaneous coronary intervention （PCI）. Simultaneous multiple coronary arteries throm-bosis is uncommon and can lead to a fatal outcome. Careful attention should be given to identification of abnormal ECG and coronary angiography （CAG） results. The affected ves- sel should be opened timely and efficiently in an effort to save the myocardium and reduce serious complications such as congestive heart failure, ventricular arrhythmia, cardiogenic shock, or sudden cardiac death.
