Bifurcation lesions are the most frequently approached complex coronary lesions in everyday interventional practice. Bifurcations complexity relies essentially on their very specific anatomy that is imperfectly handled by current coronary devices and, despite dedicated techniques and drug-eluting stents, percutaneous coronary interventions directed toward the treatment of bifurcations are technically demanding and require proper execution. Kissing balloon (KB) inflation was the first specific bifurcation technique to have been developed for percutaneous bifurcation interventions and continues to currently play an important role. Indeed, KB has been proposed to optimize stent apposition, improve side branch access while correcting stent deformation or distortion. Over the years, the KB technique has been deeply investigated by many different methods, from bench testing and computer simulations to in vivo intravascular imaging and clinical studies, producing a large amount of data pointing out the benefits and limitations of the technique. We sought to provide here a comprehensive overview of all those aspects.
分叉病变是日常介入治疗中最常遇到的复杂冠状动脉病变。分叉病变的复杂性主要取决于其非常特殊的解剖结构，而目前的冠状动脉器械并不能很好地处理这些病变。尽管有专门的技术和药物洗脱支架，但针对分叉病变的经皮冠状动脉介入治疗在技术上要求很高，需要正确执行。球囊对吻（KB）扩张是最早开发用于经皮分叉介入治疗的专门分叉技术，目前仍发挥着重要作用。实际上，KB 被提议用于优化支架贴壁、改善边支血管的可达性，同时纠正支架变形或扭曲。多年来，KB 技术已经通过许多不同的方法进行了深入研究，包括 bench testing 和 computer simulations 到体内血管内成像和临床研究，产生了大量的数据，指出了该技术的优缺点。我们试图在这里全面概述所有这些方面。
