Guidewire manipulation may be the deciding factor for success in percutaneous transluminal coronary angioplasty (PTCA) A case involving a complex lesion forming an acute angle within the left anterior descending (LAD) coronary artery, which precluded guidewire advancement, is presented. Successful dilatation was achieved after an unusual guidewire maneuver.
导丝操作可能是经皮腔内冠状动脉成形术（PTCA）成功的决定性因素。本文介绍了一例涉及左前降支（LAD）冠状动脉内形成锐角的复杂病变，导致导丝无法推进的病例。经过一次不同寻常的导丝操作后，成功实现了扩张。
