A novel approach to define risk of stent thrombosis after percutaneous coronary intervention with drug-eluting stents: the DERIVATION score.
2009
Recent studies of drug-eluting stents (DES) use in routine clinical practice have led to concern regarding their long-term safety and to questions about the adequacy of current antiplatelet therapy guidelines. This study sought to derivate a risk score for predicting stent thrombosis after drug-eluting stenting. The large single center DES Real-world Incremental Value in the erA of percutaneous revascularizaTION (DERIVATION) database, collecting data about 1,377 patients of any age undergoing PCI with DES as treatment for symptomatic coronary artery disease, was use for this purpose. Logistic regression and bootstrap procedure were used to select correlates of stent thrombosis that were sub…
Combination of high bolus dose of tirofiban with half dose thrombolytics for the treatment of subacute stent thrombosis
2005
Acute stent thrombosis is rare and it is usually related to complications during the procedure. Subacute thrombosis is far more common and is associated with a high incidence of acute myocardial infarction and death. Restoration of flow by thrombolysis, emergency bypass surgery or emergency percutaneous transluminal coronary angioplasty (PTCA) has had only limited success with respect to myocardial salvage. We report the case of a patient who suffered from recurrent subacute stent thrombosis, in whom administration of tirofiban at high-dose bolus in association with a half dose of recombinant tissue plasminogen activator succeeded in restoring normal myocardial flow and stable clinical cond…
Coronary Stent Strut Fractures: Classification, Prevalence and Clinical Associations
2021
Introduction. The frequency, characteristics and clinical implications of Strut fractures (SFs) remain incompletely understood. Methods and results. A total of 185 (160 patients) newer-generation drug-eluting stents (DES) were imaged. SFs were found in 21 DES (11.4%) and were classified in four patterns: one single stacked strut (41%)
