During coronary angiography of right coronary artery (RCA), a catheter wedged into a conus artery, and a remarkable coved-type ST elevation was seen in precordial lead through V1-3. LCA angiography did not show any abnormal findings, but we recognized a slow contrast flow in a conus artery by RCA angiography. The patient was free from chest pain, and a ST elevation was improved. The slow flow of a conus artery was recovered within five minutes. Precordial ST elevation may be caused by a catheter-induced spasm of a conus artery.
在右冠状动脉(RCA)冠状动脉造影期间,一根导管楔入圆锥动脉,并且在前胸导联V1 - 3中可见明显的穹窿型ST段抬高。左冠状动脉造影未显示任何异常发现,但我们通过右冠状动脉造影识别出圆锥动脉内造影剂流动缓慢。患者无胸痛,ST段抬高有所改善。圆锥动脉的缓慢血流在五分钟内恢复。前胸ST段抬高可能由导管诱发的圆锥动脉痉挛引起。
