Background. In the setting of coronary artery dissection, both spontaneous and iatrogenic, fixing the intimal tear, usually with stent implantation, can be extremely challenging if the distal wire position has been lost. Common complications are mainly related to the inadvertent subintimal tracking of the guidewire while attempting to gain the distal true lumen. Aims. To report the registry results of using the SUOH 0.3 guidewire for managing coronary artery dissection in a real-world multicenter setting. Methods. The study population in this retrospective, multicenter, international registry included 75 consecutive patients who underwent PCI and required an antegrade wiring of a dissected coronary artery. Results. Successful use of SUOH 0.3 was achieved in 69 (92%) patients. The use of a microcatheter was associated with a significantly higher rate of TIMI 3 flow at the end of the procedure (no microcatheter: n = 17, 81%; microcatheter: n = 52, 96.3%;  = 0.017). The first recanalization attempt was made with the SUOH 03 guidewire in 48 (64%) cases, and it was successful in 42 (87%). The overall PCI success rate was reported in 72 (96%) patients, with no significant differences among patients with different origins, mechanisms, and locations of dissection. Conclusions. In this setting, the SUOH 0.3 guidewire provides high procedural success without additional complex techniques.

SUOH 03 冠状动脉夹层管理导丝：来自多中心登记处的见解

背景。在冠状动脉夹层（自发性和医源性）的情况下，如果远端导丝位置丢失，通常通过支架植入来修复内膜撕裂可能会极具挑战性。常见并发症主要与试图获得远端真腔时无意中跟踪导丝内膜下有关。目标。报告在真实多中心环境中使用 SUOH 0.3 导丝管理冠状动脉夹层的登记结果。方法。这项回顾性、多中心、国际登记的研究人群包括 75 名连续接受 PCI 并需要对解剖冠状动脉进行顺行布线的患者。结果。69 名 (92%) 患者成功使用 SUOH 0.3。微导管的使用与手术结束时显着较高的 TIMI 3 流量相关（无微导管：n  = 17, 81%；微导管：n  = 52, 96.3%； = 0.017）。48 例 (64%) 例患者使用 SUOH 03 导丝进行了首次再通尝试，其中 42 例 (87%) 例成功。72 名患者 (96%) 报告了 PCI 的总体成功率，不同起源、机制和夹层位置的患者之间没有显着差异。结论。在这种情况下，SUOH 0.3 导丝无需额外的复杂技术即可实现很高的手术成功率。
