主动脉-冠脉开口病变的介入治疗一直是冠状动脉(冠脉)介入领域的一大难题。与非开口病变相比,其手术成功率及远期临床预后也较差[1-3]。其中,支架定位不准确是影响介入治疗效果的重要因素之一[4-5]。传统二维冠脉造影是目前最常用最安全的指导主动脉-冠脉开口病变介入治疗的影像学技术,然而有文献报道,其支架异位发生率较高[6]。血管内超声(IVUS)虽然能够对病变性质、
Interventional treatment of aortic-coronary ostial lesions has been a major challenge in the area of coronary (coronary) intervention. Compared with non-open lesions, the success rate of surgery and long-term clinical prognosis is poor [1-3]. Among them, the inaccurate positioning of the stent is one of the important factors affecting the interventional effect [4-5]. Conventional two-dimensional coronary angiography is by far the most commonly used and safest method for the interventional treatment of aortic-coronary ostial lesions. However, there is a literature report that there is a high incidence of ectopic stenting [6]. Intravascular ultrasound (IVUS) although the nature of the disease,
