The efficacy and safety of percutaneous coronary intervention (PCI) for coronary artery disease has been established, and approximately 250,000 PCI procedures are performed annually in Japan. However, various complications including life-threatening complications can occur during PCI. Although several bailout procedures have been proposed to address complications during PCI, it is critically important for operators to manage each complication in real catheter rooms with confidence even in emergent situations. Standard bailout methods including specific techniques should be clarified as algorithms and shared with inexperienced operators as well as experienced operators. The Task Force of the Japanese Society for Cardiovascular Intervention and Therapeutics (CVIT) has developed the expert consensus document on bailout algorithms for complications in PCI.

经皮冠状动脉介入治疗（PCI）治疗冠状动脉疾病的有效性和安全性已得到证实，在日本每年约有25万例PCI手术。然而，PCI术中可能出现各种并发症，包括危及生命的并发症。虽然已经提出了几种救助程序来解决PCI期间的并发症，但对于操作者来说，即使在紧急情况下，也要在真实的导管室中充满信心地处理每一种并发症。包括具体技术在内的标准救助方法应明确为算法，并与经验丰富的操作人员共享。日本心血管干预和治疗学会（CVIT）工作组已经制定了PCI并发症救助算法的专家共识文件。
