UNASSIGNED: Single-center retrospective analysis of a prospective cohort PCI registry study included 80 patients (100 lesions) who underwent successful DCB angioplasty between January 2020 and October 2023 and follow-up angiography within 2 years of either planned or unplanned reason. Incidence and factors associated with TLR were analyzed.
UNASSIGNED: Angiographic evaluation was conducted within a median of 151 days (interquartile range: 109 days). During index procedure, 54% were complex lesions. Intravascular imaging (IVI) was performed in 80% of lesions. TLR occurred in 11% of the lesions and was less frequent in the IVI group compared to the angiography-alone group [6.3 vs. 54.5%; odds ratio: 0.156, 95% confidence interval (CI): 0.042-0.580; p = 0.002]. No association was found between baseline and lesion characteristics, lesion complexity, plaque morphology, pre-dilatation procedure balloon type, maximal inflation pressure, or length of DCB between the groups (p > 0.05). Multivariate analysis revealed that IVI utilization was independently associated with a lower TLR rate (adjusted odds ratio: 0.116, 95% CI: 0.020-0.669; p = 0.016).
UNASSIGNED: In DCB angioplasty, only IVI use exhibited a significant difference in the TLR rate among baseline lesion characteristics and lesion preparation and was independently associated with a lower TLR rate.
■一项前瞻性队列PCI注册研究的单中心回顾性分析包括在2020年1月至2023年10月期间成功接受DCB血管成形术的80例患者(100个病灶),并在计划内或计划外原因的2年内进行了血管造影随访。分析TLR的发生率及相关因素。
■在151天的中位数内进行血管造影评估(四分位距:109天)。在索引过程中,54%为复杂病变。在80%的病变中进行了血管内成像(IVI)。TLR发生在11%的病变中,与单纯血管造影组相比,IVI组的发生率较低[6.3vs.54.5%;比值比:0.156,95%置信区间(CI):0.042-0.580;p=0.002]。基线和病变特征之间没有发现关联,病变复杂性,斑块形态,预扩张程序球囊类型,最大充气压力,或组间DCB的长度(p>0.05)。多变量分析显示,IVI利用率与较低的TLR率独立相关(校正比值比:0.116,95%CI:0.020-0.669;p=0.016)。
■在DCB血管成形术中,仅IVI使用在基线病变特征和病变准备中显示TLR率存在显著差异,并且与较低TLR率独立相关.
