Successful Drug-Eluting Stent Overexpansion with Intravascular Ultrasound Guidance for Left Main Bifurcation Lesion Via Left Snuffbox Approach A 60 year-old man presented with a 2-day history of intermittent chest pain. Electrocardiogram showed an ST-segment elevation in lead aVR with a diffuse ST-segment depression in all precordial leads, which is suspicious for left main coronary artery disease. After loading of aspirin 300 mg and ticagrelor 180 mg, urgent coronary angiography (CAG) was performed via left snuffbox approach using 6 Fr radial sheath (Radifocus®Introducer II, Terumo Corporation, Tokyo, Japan) (Fig. 1A). CAG demonstrated the severe stenosis in the distal left main coronary artery (LMCA) that extended into proximal left anterior descending artery (LAD) (Fig. 1B, left). Therefore, intravascular ultrasound (IVUS) guided percutaneous coronary intervention (PCI) was planned. IVUS showed minimal lumen area of 2.3 mm2 with plaque burden of 86.5%, a proximal and distal reference vessel diameter of 5.45 mm and 3.95 mm, respectively (Fig. 1C-E).
