ST-Segment Elevation in Inferior Leads Associated with Acute LAD Stent Thrombosis

A 45 year-old man was admitted to emergency service with new onset chest pain for 30 minutes. Electrocardiogram (ECG) showed ST-segment elevation in D1, AVL and V1-V6 leads and coronary angiography (CAG) detected proximal total occlusion of left anterior descending artery (LAD). Primer percutaneous intervention (PCI) was performed. Following intervention, ECG was normalized. Twenty minutes after PCI chest pain re-emerged and ECG showed ST-segment elevation in the D2, D3 and AVF leads. The patient was immediately transferred to catheterization laboratory and CAG showed acute LAD stent thrombosis. The culprit was successfully treated and the patient was discharged after three days with no complaint.
