We report on the case of a 59-year-old man who presented with continuous chest discomfort. The patient's initial electrocardiogram (ECG) showed normal sinus rhythm. Coronary angiography showed significant stenosis in the proximal left anterior descending coronary artery (LAD), the distal left circumflex coronary artery (LCX). Therefore, we deployed a stent in the proximal LAD and the distal LCX. Two days after percutaneous coronary intervention (PCI), he complained of atypical chest pain. His ECG showed ST segment elevation in leads V1 to V3. In emergent coronary angiography, there was no stent thrombosis. ECG findings showed that the ST segment has a "saddle back" ST-T wave configuration in which the elevated ST segment descends toward the baseline, then rises again to an upright T wave, like the Brugada ECG pattern. This case report shows how dynamic ST segment elevations may look similar in cases of stent thrombosis after PCI.
