目标.通过使用不同的球囊充盈时间和压力来评估冠状动脉支架的扩张模式。背景冠状动脉支架尺寸的选择及其正确部署在冠状动脉介入治疗中至关重要，对手术的成功和进一步治疗有影响。方法.在标称压力下使用顺序（5、5、10和10秒重复充盈，因此汇总时间为30秒）和连续（30秒）展开模式展开10对不同的支架。在每个给定时间点后，通过光学相干断层扫描（OCT）和血管内超声（IVUS）进行腔内支架测量。结果OCT在所有连续时间点测量的成对支架的支架内直径和横截面积（CSA）均显著小于给定制造商图表的值（直径为90%至94%，CSA为81%至88%，p
Objectives. To assess the expansion pattern of coronary stents by using different balloon inflation times and pressures. Background. The selection of coronary stent size and its proper deployment is crucial in coronary artery interventions, having an impact on the success of the procedure and further therapy. Methods. Ten pairs of different stents were deployed under nominal pressure using sequential (5, 5, 10, and 10 seconds of repeated inflations, thus 30 seconds of summarized time) and continuous (30 seconds) deployment pattern. After each given time-point, intraluminal stent measurements were performed by optical coherence tomography (OCT) and intravascular ultrasound (IVUS). Results. Both in-stent diameters and cross-section areas (CSA) of paired stents measured by OCT at all sequential time-points were significantly smaller compared to given manufacturers charts' values (90% to 94% for diameters and 81% to 88% for CSA, p
