RESUMO
A 60-year-old man was referred to our hospital because of dyspnea on exertion. He was diagnosed with heart failure due to an old myocardial infarction. Myocardial stress perfusion scintigraphy revealed inducible myocardial ischemia. Coronary angiography revealed hazy slit lesions in both the left anterior descending (LAD) and right coronary arteries (RCA). We first performed percutaneous coronary intervention (PCI) on the LAD lesion. Subsequently, we performed PCI for the RCA lesion using multiple imaging modalities. We observed a lotus root-like appearance in both the LAD and RCA, and PCI was successful for both vessels. We describe this rare case in detail.

We describe a 41-year-old woman who presented with acute ST-segment elevation myocardial infarction. Emergent percutaneous intervention was performed with aspiration thrombectomy followed by coronary artery stenting. White material was extracted from the aspiration catheter. Reperfusion therapy after stenting was successful. After undergoing a cardiac rehabilitation program, she was discharged from hospital on day 10. Pathological examination revealed that the aspirated material consisted of normal vascular components including endothelial and smooth muscle cells. Aspiration thrombectomy is a commonly used procedure with a low complication rate. This case presents the previously unreported complication of coronary artery injury.
