Phantom Stent Thrombosis: Intracoronary Imaging Insights
A 72-old-year-man was admitted for an inferior ST-segment elevation acute myocardial infarction. Seven years earlier, a 2.75 × 15-mm bare-metal stent (BMS) was successfully implanted in the posterolateral branch of the right coronary artery (RCA) at another institution. Emergent coronary angiography showed a thrombotic occlusion at the mid-segment of the RCA (Figure 1 ). After multiple unsuccessful attempts to cross the occlusion, eventually a hydrophilic guidewire was advanced across the occluded segment. Thromboaspiration was unsuccessful despite the use of 2 different aspiration devices that were unable to cross the lesion. Optical coherence tomography (OCT) was performed to clarify the underlying substrate ...
