Deferred Stenting in Primary Angioplasty could reduce No Reflow Risk and Infarct Size.

Original: A Randomized Trial of Deferred Stenting versus Immediate Stenting to Prevent No-or Slow Reflow in Acute ST-Elevation Myocardial Infarction (DEFER-STEMI). Reference: David Carrick et al. J Am Coll Cardiol. 2014. Epub ahead of print. No Reflow physiopathology involves microvascular obstruction secondary to thrombus embolization, spasm or microvascular thrombosis, and happens in approximately 10% of PCI procedures. The...

At least one month of antiplatelet seems sufficient after a zotarolimus -eluting stent

Original title: Lack of association between dual antiplatelet therapy use and stent thrombosis between 1 and 12 months following Resolute zotarolimus-eluting stent implantation. Reference: Silber S, Kirtane AJ, Belardi JA, et al. Eur Heart J. 2014; Epub ahead of print. Dual antiplatelet aggregation optimal time after implantation of a new generation drug-eluting stent (DES) is still discussed. This...

The length of the stent is not an event predictor with the new generation of DES. It is the end of the Spot stenting?

Original title: Impact of the Stent Length on Long-Term Clinical Outcomes Following Newer-Generation Drug-Eluting Stent Implantation. Reference: Ik Jun Choi et al. Am J Cardiol 2014;113:457-464. Completely cover the lesion with a sufficiently long stent has been the preferred strategy that emerged from drug-eluting stents (DES). However, for the first-generation DES stent length has been a predictor of...

3rd generation zotarolimus-eluting stent non- inferior to everolimus

Original title: Third-generation zotarolimus-eluting and everolimus-eluting stents in all-comer patients requiring a percutaneous coronary intervention (DUTCH PEERS): a randomized, single-blind, multicentre, non-inferiority trial. Reference: Von Birgelen C et al. The Lancet. 2014; Epub ahead of print. In the 3rd generation zotarolimus-eluting stent, platform was modified to increase flexibility and make implant easier in complex lesions. This study was...

Malapposition in drug-eluting stents. Much more common and much less serious than we thought

Original title: Incidences, Predictors, and Clinical Outcomes of Acute and Late Stent Malapposition Detected by Optical Coherence Tomography After Drug-Eluting Stent Implantation Reference: Im E. et al. CircCardiovascInterv. 2014 Jan 14. [Epubahead of print]   This paper analyzed the imaging of 351 patients by optical coherence tomography (OCT) who received drug-eluting stents over 356 lesions between 2009 and...

Stent reestenosis, the only subgroup that benefits from longer double antiaggregation

Original title: Short vs. Long Term Duration of Dual Antiplatelet Therapy in Patients treated for InstentRestenosis. A PRODIGY Trial substudy. Reference: Gianluca Campo el al. J Am CollCardiol, article in press.   In the study PRODIGY (Prolonging Dual Antiplatelet Treatment After Grading Stent- Induced Intimal Hyperplasia) we found that the 24 months ratio of dual antiaggregation was not...

Everolimus -eluting stent to 3 years, most security was the key difference.

Original title: Everolimus-eluting stents in patients undergoing percutaneous coronary Intervention: Final 3-year results of the Clinical Evaluation of the XIENCE V Everolimus Eluting Coronary Stent System in the Treatment of Subjects With de Novo Native Coronary Artery Lesions trial. Reference: Sorin J. Brener et al. Am Heart J 2013;0:1-8. The XIENCE stent (Abbott Vascular, Santa Clara, CA) is...

Primary angioplasty with 2nd generation drug-eluting stents

Original title: Stent thrombosis with second-generation drug-eluting stents compared with bare-metal stents: Network meta-analysis of primary percutaneous coronary intervention trials in ST-segment–elevation myocardial infarction. Reference: Circ Cardiovasc Interv. 2013; Epub ahead of print. To compare the safety and efficacy of 2nd generation drug-eluting stents (DES) versus bare metal stents (BMS) in the context of primary angioplasty was conducted...

Similar results of drug-eluting stents with biodegradable polymer versus permanent

Original title: Biodegradable Polymer Biolimus-Eluting Stent Versus Durable Polymer Everolimus-Eluting StentA Randomized, Controlled, Noninferiority Trial.NEXT trial. Reference: Masahiro Natsuaki et al. J Am CollCardiol 2013;62:181–90. Drug-eluting stents with biodegradable polymer were designed to counteract the long-term adverse effects on the vascular wall of permanent polymer.  This prospective, multicenter, randomized, non-inferiority design study, compared the biolimus eluting stent with...
