Placement of the directional coronary atherectomy cutter requires frequent angiographic contrast injections to aid in the precise location of the device in relation to the target stenosis. A method is described to enable rapid positioning of this device across stenotic lesions occurring in the left anterior descending coronary artery, with the use of a simple lesion marker. Two short lines demarcating the limits of the stenotic lesion are drawn onto a transparent one-sided adhesive plastic sheet that has been pasted beforehand onto the active monitor screen. Using this reference marker, the atherectomy device can be reliably positioned across the stenotic lesion.
定向冠状动脉斑块旋切刀的放置需要频繁进行血管造影剂注射，以帮助精确确定该装置相对于目标狭窄的位置。本文描述了一种方法，通过使用简单的病变标记物，能够快速将该装置放置在左前降支冠状动脉出现的狭窄病变处。在预先粘贴到活动监测屏幕上的透明单面粘性塑料片上绘制两条划定狭窄病变范围的短线。使用这个参考标记物，可以将斑块旋切装置可靠地放置在狭窄病变处。
