Guide catheter tip-induced type-II aortocoronary dissection bailed out by stenting the left main coronary artery

Abstract

Left main coronary artery dissection induced by the tip of the guide catheter (Razor blade effect) with or without extension into the adjacent aortic wall can result in no flow. It is being a life threatening, complication and must be time timely detected and treated by stenting or surgery. A 59-year-old male patient presented with crescendo angina having a history of stenting to left anterior descending coronary artery (LAD) using 3 mm × 23 mm drug-eluting stent 5 years back. Coronary angiogram revealed 100% instent re-stenosis of the LAD. Left circumflex (LCX) coronary artery had proximal chronic total occlusion with J-CTO score of ≥2.The dominant right coronary artery was normal. LMCA dissection was noticed like an invisible dragon from nowhere after stenting of the proximal LCX followed by abrupt retrograde extension into aorta, resulting in no flow in the left coronary artery. The true lumen of LMCA was re-wired, and timely bailout stenting from LMCA to LCX was performed.
