Abstract：
BACKGROUND: Antegrade dissection and re-entry (ADR) is an integral part of the hybrid algorithm, which has allowed for improved outcomes in chronic total occlusion (CTO) coronary intervention (PCI).
METHODS: A new ADR method, Subintimal Antegrade FEnestration and Re-entry (SAFER), is described. The results of a first-in-man series are presented.
RESULTS: SAFER was performed on seven consecutive patients with angiographic and clinical success in all patients.
CONCLUSIONS: This first-in-man study has shown that the SAFER technique is feasible and effective with the possibility of improving the antegrade PCI CTO success rate.

摘要：
背景：顺行解剖和重新进入（ADR）是混合算法的组成部分，这改善了慢性完全闭塞（CTO）冠状动脉介入治疗（PCI）的结局。
方法：一种新的ADR方法，次级顺行FEnestrationandre-entry(SAFER),被描述。介绍了先人系列的结果。
结果：SAFER是对所有患者中7例连续血管造影和临床成功的患者进行的。
结论：这项首次研究表明，SAFER技术是可行和有效的，有可能提高顺行PCICTO成功率。
