5Fr Heartrail ST01导管在冠心病复杂病变介入治疗中的应用经验

Application of 5Fr Heartrail ST01 Cathether in Complex Percutaneous Coronary Intervention

目的:评价5Fr Heartrail ST01导管在冠心病复杂病变介入治疗中的输送支撑作用。方法:连续入选2012年10月至2014年02月南京市第一医院所有冠心病介入治疗过程中使用5Fr Heartrail ST01导管的病例,回顾性分析患者基线特征、病变特征和手术经过及器械成功率。结果:共有33例患者介入术中使用5Fr Heartrail ST01导管,剔除10例并非处理冠状动脉狭窄病变而使用5Fr Heartrail ST01导管的患者,共有23例冠心病患者采用5Fr Heartrail ST01导管增强支撑,协助球囊和/或支架通过病变。5Fr Heartrail ST01导管的器械成功率为86.96%。其中2例器械失败患者采用Tornus穿通导管补救成功;1例改用6F AL 1.0指引导管补救成功。手术成功率为91.30%,1例无法继续配合而手术失败;1例因出现非血流限制性夹层而失败。结论:5Fr Heartrail ST01导管为冠心病复杂病变介入治疗提供优秀的支撑,提高手术成功率。

Objective： The aim of this study is to evaluate the backup support role of 5Fr Heartrail ST01 catheter in the complex percutaneous coronary intervention（PCI）. Methods： Patients using the 5Fr Heartrail ST01 catheter from October, 2012 to February, 2014 in Nanjing First Hospital were consecutively enrolled into this study. The baseline characteristics, angiographic results, interventional procedures as well as device success rate were retrospectively analyzed. Results： From all the 33 patients using 5Fr Heartrail ST01 catheter, 10 patients were excluded because 5Fr Heartrail ST01 catheter was not utilized in the interventional procedures of coronary stenotic lesions. Of 23 patients in whom 5Fr Heartrail ST01 catheter was used to assist balloon and/or stent passage, the device success rate was 86.96 %. Tornus penetrating catheter was successfully used in 2 patients with failed attempts using 5Fr Heartrail ST01 catheter.Another patient with 5Fr Heartrail ST01 catheter device failure transferred to bailout 6F AL 1.0 GC to complete the PCI. The final procedural success rate was 91.30 %. 1 patient unwilling to further cooperate and 1 patient with non-flowing limiting dissection of the target vessel failed. Conclusions： 5Fr ST01 catheter provided excellent backup support and improved procedural success during PCI of complex lesions.
