A 59 year old man was admitted to hospital with a non-transmural anterior myocardial infarction. Recurrent angina pectoris eight days after the initial infarction was investigated by cardiac catheterisation, which showed moderate anterior hypokinesis and proximal occlusion of the left anterior descending coronary artery. The distal part of this vessel was opacified via collaterals from the right coronary artery. Percutaneous transluminal coronary angioplasty was attempted during the same catheterisation; good positioning of the balloon catheter was confirmed by the use of retrograde opacification of the distal part of the left anterior descending coronary artery via the collateral vessels and dilatation was safely achieved. Opacification of the contralateral coronary artery may be a useful and safe positioning of guide wire system or balloon dilatation catheter when dilatation of a totally occluded coronary artery is attempted.
一名59岁男性因非透壁性前壁心肌梗死入院。初次梗死后8天出现复发性心绞痛，通过心脏导管检查进行评估，结果显示前壁中度运动减弱以及左前降支冠状动脉近端闭塞。该血管的远端通过来自右冠状动脉的侧支血管显影。在同一次导管检查期间尝试了经皮腔内冠状动脉成形术；通过侧支血管对左前降支冠状动脉远端进行逆行显影，确认了球囊导管的良好定位，并安全完成了扩张。当尝试扩张完全闭塞的冠状动脉时，对侧冠状动脉显影可能有助于导丝系统或球囊扩张导管的安全定位。
