Percutaneous coronary intervention (PCI) for bifurcation lesions presents several difficulties and often results in suboptimal procedural, postprocedural clinical outcomes. While the provisional 1-stent strategy is generally favored for its simplicity and favorable outcomes, a few studies suggest no significant difference between 1-stent and 2-stent techniques for true bifurcation lesions. Drug-eluting balloons (DEBs) have demonstrated potential in small vessel disease, including bifurcation side branches. However, no studies have compared the 2-stent strategy with the provisional 1-stent plus DEB strategy in non-LM true bifurcation lesions. Our study aims to address this gap by comparing these strategies, with a focus on real-world practice and detailed endpoint analysis. The PROVISION-DEB study is an open-label, randomized, multicenter clinical trial designed to investigate noninferiority and compare a 1-stent strategy with a drug-eluting balloon and a planned 2-stent strategy at non-LM coronary true-bifurcation lesions. A total of 750 patients with de novo non-LM coronary bifurcation lesions undergoing coronary interventions will be randomized 1:1 to either a provisional 1-stent plus DEB strategy or a 2-stent strategy with stratified Diabetes. The primary endpoint is a target lesion failure, composite outcome of cardiac death, target vessel myocardial infarction, or target lesion revascularization at the anticipated 3 years follow-up (6, 12, and 36 months). In conclusion, PROVISION-DEB study is a randomized, multicenter, noninferior clinical trial and will compare a 1-setnt strategy with a drug-eluting balloon and a planned 2-stent strategy at non-LM coronary true-bifurcation.
经皮冠状动脉介入治疗(PCI)用于分叉病变存在诸多困难,且常常导致手术过程及术后临床结果欠佳。虽然临时单支架策略因其简单性和良好的结果而通常受到青睐,但一些研究表明,对于真正的分叉病变,单支架技术和双支架技术之间没有显著差异。药物洗脱球囊(DEB)已在包括分叉侧支在内的小血管疾病中显示出潜力。然而,尚无研究在非左主干真正分叉病变中比较双支架策略与临时单支架加DEB策略。我们的研究旨在通过比较这些策略来填补这一空白,重点关注实际临床实践和详细的终点分析。PROVISION-DEB研究是一项开放标签、随机、多中心临床试验,旨在研究非劣效性,并比较在非左主干冠状动脉真正分叉病变处的单支架策略与药物洗脱球囊及计划中的双支架策略。总共750例接受冠状动脉介入治疗的初发非左主干冠状动脉分叉病变患者将按1:1随机分为临时单支架加DEB策略组或分层糖尿病患者的双支架策略组。主要终点是在预期的3年随访(6个月、12个月和36个月)时的靶病变失败,即心脏死亡、靶血管心肌梗死或靶病变血运重建的复合结局。总之,PROVISION-DEB研究是一项随机、多中心、非劣效性临床试验,将在非左主干冠状动脉真正分叉病变处比较单支架策略与药物洗脱球囊及计划中的双支架策略。
