Background
Slow-flow/no-reflow phenomenon is mainly induced by distal embolization of thrombus and necrotic core during PCI of ACS and non-ACS patients and is associated with unfavorable long-term clinical outcomes. Various imaging modalities have failed to detect high-risk patients of distal embolization for whom distal protection might be beneficial.
Objectives
The objectives were to examine the frequency of distal embolization using filter-type distal protection device and to clarify the predicting factors of distal embolization.
