Objectives. This study aimed to investigate the optimal jailed balloon inflation in the side branch during the modified jailed balloon technique for bifurcated lesions. Background. The modified jailed balloon technique is one of the effective techniques to minimize the emergence of side branch (SB) compromise by preventing plaque or carina shifting during a single stent strategy in the main vessel with provisional SB treatment. However, there are no detailed studies on the method of optimal jailed balloon inflation. Methods. We analyzed 51 consecutive patients who underwent percutaneous coronary intervention (PCI) for bifurcated lesions with a modified jailed balloon technique between September 2018 and December 2020. These 51 patients were divided into two groups according to the magnitude of inflation pressure of the jailed balloon: a higher pressure (HP) group and lower pressure (LP) group. Results. No significant differences in procedural outcomes were observed between the two groups. The findings of SB compromise were relatively common with our procedure (30.0% in the HP group; 33.3% in the LP group). The patterns of SB compromise such as dissection or stenosis increase were observed at similar frequencies between them. In particular, SB dissection was noted in the SB lesion with some plaque burden, irrespective of the magnitude of the jailed balloon inflation pressure. Univariate analysis showed that calcification in the main vessel and SB lesion length was significantly associated with SB compromise. Finally, all PCI procedures were successfully completed without any provisional stent deployment in SB. Conclusions. We speculate that lesion characteristics rather than the PCI procedural factors may be critical determinants to cause SB compromise.

改进的监禁气球技术中的侧支充气压力不影响支支结果

目标。本研究旨在研究改良的监禁球囊技术在治疗分叉病变时侧支的最佳监禁球囊充气。背景。改良的监禁球囊技术是一种有效的技术,通过在临时 SB 治疗的主血管中的单支架策略期间防止斑块或隆突移位,最大限度地减少侧支 (SB) 损害的出现。然而,目前还没有关于最佳监禁气球充气方法的详细研究。方法. 我们分析了 2018 年 9 月至 2020 年 12 月期间使用改良的监禁球囊技术接受经皮冠状动脉介入治疗 (PCI) 治疗分叉病变的连续 51 名患者。这 51 名患者根据监禁球囊的充气压力大小分为两组:高压(HP)组和低压(LP)组。结果. 两组的手术结果没有显着差异。SB 妥协的结果在我们的手术中相对常见(HP 组 30.0%;LP 组 33.3%)。在它们之间以相似的频率观察到 SB 妥协的模式,例如夹层或狭窄增加。特别是,在 SB 病变中发现 SB 夹层有一些斑块负荷,而与被监禁的球囊充气压力的大小无关。单变量分析表明,主血管钙化和 SB 病变长度与 SB 损害显着相关。最后,所有 PCI 程序都成功完成,而 SB 没有任何临时支架部署。结论. 我们推测病变特征而不是 PCI 程序因素可能是导致 SB 妥协的关键决定因素。
