Bifurcation lesions are common and associated with higher risks of major cardiac events and restenosis after percutaneous coronary intervention (PCI). Treatment requires understanding of lesion characteristics, stent design and therapeutic options. We review the evidence for provisional vs 2-stent techniques. We conclude that provisional stenting is suitable for most bifurcation lesions. We detail situations where a 2-stent technique should be considered and the steps for performing each of the 2-step techniques. We review the importance of lesion preparation, intracoronary imaging, proximal optimization (POT) and kissing balloon inflation.
分叉病变很常见，并且与经皮冠状动脉介入治疗（PCI）后发生重大心脏事件和再狭窄的较高风险相关。治疗需要了解病变特征、支架设计和治疗选择。我们回顾了临时支架技术与双支架技术的相关证据。我们得出结论，临时支架置入术适用于大多数分叉病变。我们详细说明了应考虑采用双支架技术的情况以及执行每种双支架技术的步骤。我们回顾了病变预处理、冠状动脉内成像、近端优化（POT）和球囊对吻扩张的重要性。
