Abstract

The second-generation drug-eluting stent (DES) reportedly has an antithrombotic effect. An 80-year-old man with acute myocardial infarction (AMI) underwent primary percutaneous coronary intervention. He received both a bare-metal stent (BMS) and a DES at that time, and underwent intravascular ultrasound and coronary angioscopy in the acute and subacute phases. Thrombi were detected in both the BMS and DES in the acute phase. However, thrombus was only detected in the BMS in the subacute phase. It is important to consider the extent of thrombus formation in acute treatment. Therefore, residual thrombus should be evaluated with an intravascular imaging in the chronic phase to help reduce the risk of not only stent thrombosis but also other adverse cardiac events.
