The use of the subintimal space has allowed a massive advancement in the field of chronic total occlusion percutaneous coronary intervention (PCI). The STAR technique is the first of subintimal techniques. Despite a high acute success rate, follow-up results showed unfavorable outcomes with half of the treated patients showing restenosis/reocclusion at 6 months. We present three cases in which a modification of the STAR technique guided by intravascular ultrasound (IVUS), namely the STAR 2.0, was used as a bailout for successful PCI of chronic total occlusions.
内膜下空间的使用使得慢性完全闭塞经皮冠状动脉介入治疗（PCI）领域取得了重大进展。STAR 技术是内膜下技术的首例。尽管急性成功率较高，但随访结果显示预后不佳，6 个月时一半的治疗患者出现再狭窄/再闭塞。我们介绍了三个病例，在这些病例中，血管内超声（IVUS）引导的 STAR 技术的改良版（即 STAR 2.0）被用作慢性完全闭塞 PCI 的成功补救。
