title: Hyper-echoic plaque with high attenuation in intravascular ultrasound may predict slow flow during percutaneous coronary intervention.
abstract: One patient with acute inferior wall myocardial infarction underwent percutaneous coronary intervention following intravenous thrombolysis. Intravascular ultrasound (IVUS) before stenting revealed huge plaque burden with high attenuation underneath the hyper-echoic eccentric plaque surface. Stent deployment resulted in slow flow, which was managed with intra-aortic balloon counter-pulsation. His another lession in the mid left anterior descending artery showing eccentric hypo-echoic plaque with neither hyper-echoic surface nor high attenuation was successfully stented without causing slow flow.
