We have recently reported a novel percutaneous coronary intervention (PCI) system using a hydrophilic-coated sheathless guiding catheter (Virtual 3-Fr, Medikit, Tokyo, Japan), which provides us with less invasive angioplasty and a puncture site injury equivalent to a conventional 3-Fr introducer sheath. Here, we report the initial results of PCI using this novel system.
A total of 36 coronary artery lesions of 27 patients were treated by using a virtual 3-Fr PCI system. Procedural outcomes of virtual 3-Fr PCI were retrospectively evaluated.
The mean age was 73.0 +/- 8.7 years (range, 46-84 years), and 15 were men (56%). Access sites included the radial artery in 18 patients (67%), the brachial artery in eight patients (30%), and the femoral artery in 1 patients (4%). Among 36 lesions, seven were chronic total occlusions, and a virtual 3-Fr PCI was successful in 33 lesions (92%). Among the successfully treated 33 lesions, coronary stents were deployed in 32 (97%), and intravascular ultrasound examination was performed in 19 (58%). Hemostasis was achieved immediately after PCIs in all cases. No access-site related complications including radial artery occlusion were observed.
The performance of a virtual 3-Fr PCI system appears to be comparable to one using a regular 5-Fr guiding catheter while the puncture-site damage remains equivalent to that of a 3-Fr introducer sheath. Virtual 3-Fr PCI may have a potential to serve as a minimally invasive strategy for the treatment of coronary artery diseases.
我们最近报道了一种新型经皮冠状动脉介入治疗（PCI）系统，该系统使用亲水涂层无鞘引导导管（Virtual 3-Fr，Medikit，东京，日本），为我们提供了创伤更小的血管成形术和与传统 3-Fr 引导鞘相当的穿刺部位损伤。在此，我们报告使用该新型系统进行 PCI 的初步结果。
共对 27 例患者的 36 处冠状动脉病变采用虚拟 3-Fr PCI 系统进行治疗。回顾性评估虚拟 3-Fr PCI 的手术结果。
平均年龄为 73.0 +/- 8.7 岁（范围，46-84 岁），男性 15 例（56%）。入路包括桡动脉 18 例（67%）、肱动脉 8 例（30%）和股动脉 1 例（4%）。36 处病变中，慢性完全闭塞 7 处，虚拟 3-Fr PCI 成功 33 处（92%）。在成功治疗的 33 处病变中，32 处（97%）植入冠状动脉支架，19 处（58%）进行血管内超声检查。所有病例均在 PCI 后即刻止血。未观察到与入路相关的并发症，包括桡动脉闭塞。
虚拟 3-Fr PCI 系统的性能似乎与使用常规 5-Fr 引导导管相当，而穿刺部位的损伤与 3-Fr 引导鞘相同。虚拟 3-Fr PCI 可能成为治疗冠状动脉疾病的一种微创策略。
