Electrocardiogram showed ischemic ST-segment elevation at anterior leads. The patient was taken to the catheterization laboratory for primary percutaneous coronary intervention. ChoICE® PT (Polymer Tip) floppy guide wire crossed the lesion subintimally. Simultaneously the patient had a new onset chest pain. Coronary angiography was proceeded which revealed a dissection in the proximal LAD until first diagonal branch (D1). On the right caudal projection very long dissections were detected in the proximal to distal parts of circumflex and intermediary arteries without any limitation in the distal coronary flow.eninfo:eu-repo/semantics/closedAccessLetter1517374Q4
