Abnormal manifestations of coronary angiography. During the left coronary angiography, the contrast agent entered from the diagonal branch (C-1, yellow triangle), rapidly flowed into the left ventricle via a diffuse plexus of multiple intramyocardial fistulas (C-2, yellow triangle), and completely turbidized the left ventricle. Subsequently, the contrast agent was discharged from the left ventricle during systole (C-3, yellow triangle). (C-4) There was severe stenosis in the distal of the RCA.
