| Popis: | Coronary high-intensity plaques (HIPs) visualized by non-contrast T1-weighted imaging (T1WI) in cardiac magnetic resonance (CMR) are associated with slow-flow phenomena during percutaneous coronary intervention (PCI). We report a case of a 52-year-old man who had undergone left anterior descending artery stent implantation for unstable angina 5 years previously. He underwent CMR imaging for screening of vulnerable plaques. A lesion in the proximal right coronary artery showed HIP on non-contrast T1WI. Invasive coronary angiography showed progressive stenosis and PCI was performed. Non-contrast T1WI indicated a high risk for a slow-flow phenomenon. A distal protection device (Parachute™ (Tri-Med, Osaka, Japan)) was deployed at the distal site of the lesion. Following balloon dilation, a filter no-reflow phenomenon developed. Coronary flow was improved with removal of the Parachute™ after debris aspiration. Histological examination revealed aspirated debris composed of white thrombi, foamy macrophages, and cholesterol crystals. |
