A new angioscope was devised for easier visualization of the coronary artery. In its tip, the angioscope (Olympus) with an outer diameter of 0.8 mm had a metal lumen, through which a 0.014-in steerable guide wire passed. Using a 8F guiding catheter and a guide wire, it was introduced into the distal coronary artery. With injection of warmed saline through the guiding catheter, the coronary segments were visualized. In the attempted 70 vessels (32 left anterior descending [LAD], 10 right coronary [RCA], 28 left circumflex [LCX]) from 48 patients, 60 vessels (86%) were successfully examined. Twenty-two patients who underwent attempted examination of both LAD and LCX; both coronary arteries were visualized in 19 patients (86%). In the proximal site of the lesion, 40 patients have the diagonal branch or the obtuse marginal branch. In 34 patients (85%) the angioscope was inserted beyond these branches. In 12 very tortuous vessels, eight vessels (67%) were examined. In conclusion, the new monorail coronary angioscope with movable guide wire is useful to examine the stenotic lesions of the coronary artery.
为更便于观察冠状动脉，设计了一种新型血管镜。其顶端的血管镜（奥林巴斯）外径为0.8毫米，有一个金属管腔，一根0.014英寸的可操纵导丝可从中穿过。使用8F引导导管和导丝，将其插入冠状动脉远端。通过引导导管注入温热盐水后，可观察到冠状动脉节段。在对48例患者的70条血管（32条左前降支[LAD]、10条右冠状动脉[RCA]、28条左旋支[LCX]）进行的尝试性检查中，成功检查了60条血管（86%）。22例患者尝试对LAD和LCX进行检查；19例患者（86%）的两条冠状动脉均被观察到。在病变近端，40例患者有对角支或钝缘支。34例患者（85%）的血管镜插入超过了这些分支。在12条非常迂曲的血管中，8条血管（67%）被检查。总之，带有可移动导丝的新型单轨冠状动脉血管镜对于检查冠状动脉狭窄病变很有用。
