Abstract

Coronary atherosclerotic lesions at the ostium and proximal coronary arteries pose significant challenges in percutaneous coronary interventions (PCI), especially in the left main coronary artery (LMCA). Guide catheter-induced damage can lead to severe complications such as vessel dissection or myocardial infarction. Ostial stent placement with drug-eluting stents offers mechanical support and reduces restenosis but is technically challenging due to the anatomical complexity of the ostium. Complications like longitudinal stent deformation and hydraulic dissection from contrast media are specific concerns. The aortic free-floating wire technique, expanded in this article to Wire in Aorta for Localization and Protection of the Ostium (WALPO), provides a method for safely locating and protecting the ostium during PCI, aiming to improve the safety and efficacy of PCI at this location.

骨膜保护导丝的介入应用--WALPO 技术。
在经皮冠状动脉介入治疗(PCI)中,尤其是在左冠状动脉主干(LMCA)中,冠状动脉骨膜和近端冠状动脉的动脉粥样硬化病变构成了重大挑战。导引导管引起的损伤可导致血管夹层或心肌梗死等严重并发症。使用药物洗脱支架进行骨膜支架置入可提供机械支持并减少再狭窄,但由于骨膜解剖结构复杂,在技术上具有挑战性。造影剂引起的支架纵向变形和液压夹层等并发症是特别令人担忧的问题。主动脉自由浮动导线技术在本文中扩展为主动脉定位和保护骨膜导线(WALPO),它提供了一种在 PCI 过程中安全定位和保护骨膜的方法,旨在提高该位置 PCI 的安全性和有效性。

期刊介绍: Catheterization and Cardiovascular Interventions is an international journal covering the broad field of cardiovascular diseases. Subject material includes basic and clinical information that is derived from or related to invasive and interventional coronary or peripheral vascular techniques. The journal focuses on material that will be of immediate practical value to physicians providing patient care in the clinical laboratory setting. To accomplish this, the journal publishes Preliminary Reports and Work In Progress articles that complement the traditional Original Studies, Case Reports, and Comprehensive Reviews. Perspective and insight concerning controversial subjects and evolving technologies are provided regularly through Editorial Commentaries furnished by members of the Editorial Board and other experts. Articles are subject to double-blind peer review and complete editorial evaluation prior to any decision regarding acceptability.
