Stent fracture has received increased concern as it may be an important risk factor for late stent failure, intravascular ultrasound (IVUS) is always recommended to confirm the diagnosis of stent fracture. StentBoost can detect stent fractures more easily due to the enhanced stent strut visibility, compared with coronary angiography (CAG). Few cases were reported to compare the advantages of StentBoost vis-à-vis IVUS in detecting stent fracture.
We reported 3 cases that were confirmed the diagnosis of stent fracture by StentBoost, which were preliminarily suspected by angiography, including one case that lacked the IVUS evidence of stent fracture.
3 cases of stent fracture presented with asymptomatic, angina and acute myocardial infarction, respectively.
Stents were implanted in the patients of case 2 and case 3, but the patient of case 1 was not given any intervention.
No recurrent angina or myocardial infarction during outpatient follow-up.
StentBoost may distinguish partial, complete, or multiple stent fracture, even which sometimes is not obvious in IVUS, StentBoost is a useful and handy tool for identifying the stent struts.
支架断裂受到越来越多的关注，因为它可能是晚期支架失效的一个重要危险因素，血管内超声（IVUS）一直被推荐用于确诊支架断裂。与冠状动脉造影（CAG）相比，StentBoost由于增强了支架小梁的可视性，能够更轻松地检测到支架断裂。很少有病例报道比较StentBoost与IVUS在检测支架断裂方面的优势。
我们报告了3例经StentBoost确诊为支架断裂的病例，这些病例最初由血管造影初步怀疑，其中1例缺乏支架断裂的IVUS证据。
3例支架断裂患者分别表现为无症状、心绞痛和急性心肌梗死。
病例2和病例3的患者植入了支架，但病例1的患者未接受任何干预。
门诊随访期间无复发性心绞痛或心肌梗死。
StentBoost可以区分部分、完全或多处支架断裂，即使在IVUS中有时不明显，StentBoost是识别支架小梁的一种有用且便捷的工具。
