Very Late Amplatzer Device Thrombosis and Stroke

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 ...

Very late transcatheter heart valve thrombosis

We describe a case of very late transcatheter heart valve (THV) thrombosis of a first-generation SAPIEN prosthesis (Edwards Lifesciences, Irvine, CA) implanted in a 64-year-old woman with severe symptomatic aortic stenosis. More than 54 mo after implantation, she presented with severe symptomatic prosthesis dysfunction (stenosis) which was successfully treated with oral anticoagulation. To our ...

Very late thrombosis in a bifurcation.

A male patient 65 years old treated with a conventional stent in the second diagonal (D2) branche in 2007. In 2008, he underwent a stent-in-stent procedure for D2 in-stent restenosis, with stent implanation reaching the ostium taking off from the left anterior descending artery (LAD). In June 2011, antiplatelet treatment was discontinued due to non-cardiac surgery; the patient presented a myoca...

Very Late Bare Metal Stent Thrombosis

Very late stent thrombosis is a rare and not-well-understood complication after bare metal stent implantation. It usually presents as an ST elevation acute coronary syndrome and it is associated with high rates of morbidity and mortality. Pathophysiologic mechanisms are not well defined; nevertheless, recent studies have proposed a neoatherosclerotic process as the triggering mechanism. We pres...

Very late stent thrombosis due to late stent malapposition.
