Acute coronary closure complicating intravascular ultrasound examination.
A patient with an excellent angiographic result after directional atherectomy suffered an acute coronary closure during an intravascular ultrasound study performed after the intervention. Intravascular ultrasound revealed a large medial dissection which could be successfully managed only with intracoronary stenting. The pathogenesis and implications of this rare major complication are discussed.
