title: Visualization of a cluster of embolic particles causing angiographic no-reflow during percutaneous coronary intervention.
abstract: Angiographic no-reflow occurs occasionally during percutaneous coronary intervention in patients with acute myocardial infarction. Recently, we reported that coronary embolic particles can be detected as high-intensity transient signals with the Doppler guidewire. In the present study, the Doppler guidewire revealed that embolization of a cluster of embolic particles liberated by balloon inflation was responsible for angiographic no-reflow.
