    Thrombus Contribution to Very Late Restenosis of Bare-Metal Stent Treated by Excimer Laser Angioplasty: In Vivo Assessment with Optical Coherence Tomography
    A 75-year-old, male ex-smoker with hypertension and family history of ischemic heart disease, previous anterior myocardial infarction, and angioplasty with bare-metal stent implantation to the left anterior descending artery 4 years earlier, developed effort angina. A nuclear myocardial scan documented a stress-inducible perfusion defect in the left ventricular anterior wall. The patient was taking 100 mg aspirin daily and a 300 mg loading dose of clopidogrel was administered the day before coronary angiography. Coronary angiography showed focal proximal in-stent restenosis (Figure 1, Panel A). Optical coherence tomography (OCT) (ImageWire and Imaging System M2, LightLab Imaging, Westford, Massachusetts) was performed using ...
