Abstract
Stent thrombosis is defined as thrombotic occlusion of a stent resulting in acute coronary syndrome (ACS). However, all thrombotic occlusions of stents might not result in ACS. The present case report describes silent, very late thrombotic occlusion of a drug-eluting stent that was confirmed from specimens removed by directional coronary atherectomy.
