A novel stenting technique, using one stent strategy, designed to treat type Medina 1,0,0 coronary bifurcation lesions, is described. The atherosclerotic plaque burden in this category of bifurcation lesions is located in the proximal segment of the main branch (MB) of a coronary bifurcation in which the side branch has a sharp angulation (T- or reverse-shaped) relative to the MB. The advantages of this technique are the accurate placement of the stent tailored to cover solely the bifurcation lesion, shoving the plaque burden away from the side branch ostium during stent expansion and the ability to maintain guide wire access in the branch at highest risk of occlusion obviating the need for more cumbersome and time consuming percutaneous coronary intervention procedure.
本文描述了一种新型的支架置入技术,采用单一支架策略,旨在治疗梅迪纳1,0,0型冠状动脉分叉病变。这类分叉病变的动脉粥样硬化斑块负荷位于冠状动脉分叉主支(MB)的近端节段,其中分支相对于主支有锐角(T形或倒T形)。该技术的优点是能够精确放置支架,仅覆盖分叉病变,在支架扩张过程中将斑块负荷从分支开口处推开,并且能够在闭塞风险最高的分支中保持导丝通路,从而避免了更繁琐和耗时的经皮冠状动脉介入手术。
