RationaleStent 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.Patient ConcernsWe 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.Diagnoses3 cases of stent fracture presented with asymptomatic, angina and acute myocardial infarction, respectively.InterventionStents were implanted in the patients of case 2 and case 3, but the patient of case 1 was not given any intervention.OutcomesNo recurrent angina or myocardial infarction during outpatient follow-up.LessonsStentBoost 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.
