IMPACT OF STENT-IMPLANTED LESION ON TIMING OF STENT THROMBOSIS OCCURRENCE: EVALUATION OF SUBACUTE, LATE, AND VERY LATE STENT THROMBOSIS

Very late stent thrombosis due to late stent malapposition.

Very Late Stent Thrombosis Due to Late Stent Malapposition

Very late stent thrombosis after implantation of drug eluting stent.

A case of late stent occlusion of a Sirolimus eluting Cypher stent (Cordis, Johnson and Johnson) presenting as acute ST elevation myocardial infarction 22 months after deployment is reported. The possible mechanisms are discussed.

Late coronary stent thrombosis.

Introduced 20 years ago,1 coronary artery stents have improved the safety and particularly the efficacy of percutaneous coronary interventions (PCIs).2 Abrupt vessel closure, complicating 6% to 8% of balloon angioplasty procedures, was associated with a 5% mortality, 40% rate of myocardial infarction (MI), and 40% rate of emergency coronary artery bypass grafting.3 Stents significantly reduced ...

Triple, simultaneous, very late coronary stent thrombosis.

Coronary artery stent thrombosis is an uncommon but potentially catastrophic complication. The risk of very late stent thrombosis (VLST) raises important safety issues regarding the first generation of drug-eluting stents (DES). Although several complex mechanisms for VLST have been suggested and various predictors have been described, its pathophysiology is not completely understood and it is ...
