In the last few decades, the recommended treatment for coronary artery disease has been dramatically improved by percutaneous coronary intervention (PCI) and the use of balloon catheters, bare metal stents (BMSs), and drug-eluting stents (DESs). Catheter balloons were burdened by acute vessel occlusion or target-lesion re-stenosis. BMSs greatly reduced those problems holding up the vessel structure, but showed high rates of in-stent re-stenosis, which is characterized by neo-intimal hyperplasia and vessel remodeling leading to a re-narrowing of the vessel diameter...

Patients with unprotected left main coronary artery (ULMCA) disease are increasingly treated with percutaneous coronary intervention (PCI) using new-generation drug-eluting stents (DES); however, the benefits of DES compared with coronary artery bypass grafting (CABG) in ULMCA remain controversial. This meta-analysis evaluated the effects of PCI with DES compared with CABG for the treatment of ULMCA stenosis. Databases were searched through November 30, 2016. Randomized controlled trials (RCTs) comparing DES with PCI versus CABG for ULMCA stenosis were identified...

Drug-eluting stents (DES) represent nowadays the gold standard treatment for coronary artery disease. Despite the safety and efficacy, and favorable long-term clinical outcomes of new generation DES, their use is still associated with a not negligible risk of long-term events, related to the presence of a definitive prosthesis in the vessel wall. In addition, DES implantation is not always desirable in particular anatomic settings (small vessels, bifurcations) or in patients with higher bleeding risk. In recent years, drug-coated balloons (DCB) have been developed to overcome some of these limitations, offering a combined mechanical (balloon dilation) and biological therapy (drug-release)...

BACKGROUND: Endeavor zotarolimus-eluting stents (E-ZES) and everolimus-eluting stents (EES) as second-generation stents were approved for use in percutaneous coronary interventions (PCIs) in 2008. We aimed to evaluate the long-term outcomes of E-ZES vs. EES using New York State (NYS) cardiac registries and to compare long-term effectiveness of E-ZES vs. EES in six "off-label" and two "high-risk" subgroups. METHODS: We created a longitudinal database by linking the NYS cardiac registries, the statewide hospital discharge data, the National Death Index, and the U...

Mozhgan Shojaee, Chris A Bashur
Tissue engineering approaches for small-diameter arteries require a scaffold that simultaneously maintains patency by preventing thrombosis and intimal hyperplasia, maintains its structural integrity after grafting, and allows integration. While synthetic and extracellular matrix-derived materials can provide some of these properties individually, developing a scaffold that provides the balanced properties needed for vascular graft survival in the clinic has been particularly challenging. After 30 years of research, there are now several scaffolds currently in clinical trials...

OBJECTIVE: Carotid artery stenting (CAS) is a less invasive alternative to carotid endarterectomy, but it is essential to prevent thromboembolic complications during CAS and to suppress in-stent restenosis (ISR) after CAS because of the relatively high risk of periprocedural and follow-up stroke events. Clinical trials have demonstrated the strong relationship of carotid plaque vulnerability with the subsequent risk of ipsilateral ischemic stroke and thromboembolic complications during CAS...

Alexandre Abizaid, J Ribamar Costa
PURPOSE OF REVIEW: First-generation bioresorbable scaffolds (BRS), largely represented by the poly-l-lactic acid (PLLA) ABSORB (Abbott Vascular, Temecula, Illinois, US), have demonstrated, in low to moderate lesion complexity, similar efficacy to current generation metallic drug-eluting stents. However, a trend toward more device thrombosis has been observed, especially when the scaffolds are used in off-label situations. In this review, we address the most relevant drawbacks of these devices and, based on the available scientific data, we visit the scenarios where there is more uncertainty about their indication, trying to identify the lesions/patients to whom this technology should be voided at its current stage of development...

Presently, a new era of drug-eluting stents is continuing to improve late adverse effects such as thrombosis after coronary stent implantation in atherosclerotic vessels. The application of gene expression-modulating stents releasing specific small interfering RNAs (siRNAs) or messenger RNAs (mRNAs) to the vascular wall might have the potential to improve the regeneration of the vessel wall and to inhibit adverse effects as a new promising therapeutic strategy. Different poly (lactic-co-glycolic acid) (PLGA) resomers for their ability as an siRNA delivery carrier against intercellular adhesion molecule (ICAM)-1 with a depot effect were tested...

In the current case series we describe two cases of longitudinal stent deformation in ostial lesions treated with a new generation zotarolimus eluting stent and review current literature on longitudinal stent deformation. Historically not a common occurrence, longitudinal deformation occurred mainly in Promus Element everolimus eluting stents, which had only two rather than the commonly used 3 links between stent rings. Longitudinal deformation commonly occurs secondary to compression of the proximal edge of the stent by either the guide catheters, or intravascular balloons and imaging catheters...

Giant basilar apex aneurysms are extremely challenging to successfully manage. The Pipeline Flex embolization device (PFED) is a new generation flow-diverting stent with a modified delivery system which allows resheathing of the stent after partial deployment. We describe a case of double-barrel Y-configuration stenting of a giant, recurrent basilar apex aneurysm using the PFED. A 73-year-old male was previously treated for an unruptured 11-mm basilar apex aneurysm with stent-assisted coiling using a Neuroform stent...

Nickel is the most frequent allergen in patients with allergic contact dermatitis and nickel allergy has been associated with recurrent in-stent restenosis. However, it is often misdiagnosed because of a low suspicion threshold. It should be discarded in patients with recurrent in-stent restenosis, especially if their medical history reveals prior contact dermatitis. It is also noteworthy and rarely specified that even newer generation stents that use novel metal alloys also contain low amounts of nickel. To avoid the implantation of new stents containing this metal, when percutaneous coronary intervention is indicated, drug eluting balloons or bioresorbable vascular scaffolds associated with small doses of steroids could provide good alternatives of treatment...
