A 43-year-old woman presented with exertional chest pressure. Right coronary angiography showed a clear filling defect. Intravascular ultrasound revealed a plaque with 80% stenosis and a large lipid pool. Therefore, a stent was placed, and the patient became angina-free. Lipid-rich plaques are a cause of angiographic filling defects. Intravascular ultrasound is an integral part of coronary artery evaluation.
一名43岁女性因运动时胸部受压前来就诊。右冠状动脉血管造影显示有明显的充盈缺损。血管内超声显示一个斑块，狭窄率达80%，并有一个大的脂质池。因此，植入了一枚支架，患者心绞痛症状消失。富含脂质的斑块是血管造影充盈缺损的一个原因。血管内超声是冠状动脉评估不可或缺的一部分。
