title: Non-atherosclerotic spontaneous coronary artery dissection revascularized by intravascular ultrasonography-guided fenestration with cutting balloon angioplasty.
abstract: A 46-year-old woman was referred to our hospital due to chest pain. Twelve-lead electrocardiogram revealed ST-segment elevation suggesting acute myocardial infarction. Emergent coronary angiography showed diffuse narrowing and occlusion in the middle to distal left anterior descending artery (LAD). To investigate the cause of occlusion, an intravascular ultrasound (IVUS) examination was performed and we diagnosed spontaneous coronary artery dissection (SCAD) as the cause of occlusion. After a cutting balloon was dilated at the distal LAD, coronary flow recovered. IVUS-guided angioplasty with cutting balloon could be a choice of treatment in SCAD patients who need revascularization.
