Generations of coronary stents

Coronary stent - Wikipedia

Purpose of review: Drug-eluting stents are the mainstay in the treatment of coronary artery disease using percutaneous coronary intervention. Innovations developed to overcome the limitations of prior generations of stents include biodegradable polymer stents, drug-eluting stents without a polymer, and bioabsorbable scaffolds Percutaneous coronary intervention (PCI) is 40 years old this year. From its humble beginnings of experimental work, PCI has transitioned over years with coronary artery stenting now a standard medical procedure performed throughout the world. Areas covered: The conversion from plain old balloon ang Drug-eluting stents (DES) have revolutionized the treatment of coronary artery disease by reducing the rate of in-stent restenosis from 20-40% with bare-metal stent (BMS) to 6-8% with DES. However, with widespread use of DES, safety concerns have risen due to the observation of late stent thrombosis

A third generation of coronary devices has evolved in the late 1990s in response to continuing failures of conventional balloon angioplasty, atherectomy, and stenting. The failures of the 1990s were (1) restenosis, including in-stent restenosis, (2) chronic total occlusions, (3) diffuse small-vessel disease, and (4) aged vein graft disease Coronary stents were developed to prevent arterial recoil and restenosis after balloon dilatation. Stents can be classified into 3 large families: bare metal stents (BMS), drug-eluting stents (DES), and bioresorbable vascular scaffolds (BRS) Contemporary coronary stent technology continues to seek to improve on the outcomes of the preceding generation of devices by refining their design, structure and component materials. These technologies include new generations of drug-eluting stents, non-polymeric stents, bioresorbable polymer-coated stents, and fully bioresorbable scaffolds

Over the past 10 years, first-generation drug-eluting stents (DES), especially sirolimus-eluting stent (SES) and paclitaxel-eluting stents (PES), have become the most widely used devices worldwide for management of coronary artery disease Evolution of Technology. In 1986, the first coronary stents were implanted by Jacques Puel, MD, in France, and Ulrich Sigwart, MD, in Switzerland, marking a paradigm shift in the approach to.

Biodegradable polymer drug-eluting stents reduce the risk of stent thrombosis at 4 years in patients undergoing percutaneous coronary intervention: a pooled analysis of individual patient data from the ISAR-TEST 3, ISAR-TEST 4, and LEADERS randomized trials

A sirolimus-eluting bioabsorbable polymer-coated stent (MiStent) versus an everolimus-eluting durable polymer stent (Xience) after percutaneous coronary intervention (DESSOLVE III): a randomised, single-blind, multicentre, non-inferiority, phase 3 trial. Lancet 2018; 391:431 BACKGROUNDS: Few reports have primarily focused on long-term clinical outcomes in three-vessel disease when patients were treated with either first- or new-generation drug-eluting stents (DES). The purpose of this study was to investigate different clinical outcomes after percutaneous coronary intervention (PCI) for three-vessel disease with. The stent acts like a scaffold and helps to open the narrowed coronary arteries. Stents thus allow adequate blood supply to the heart and are left in place indefinitely. Stents are also used to.

Author information: (1)Herz-Gefässzentrum Zürich, Klinik im Park, Zürich. franz.amann@hirslanden.ch Since the introduction of coronary stents into clinical practice in the late 1980s, the number of stent implantations has increased so rapidly that stents are currently used in over 80 percent of all. Although drug-eluting stents (DES) have significantly reduced the incidence and prevalence of coronary in-stent restenosis (ISR), ISR still occurs in approximately 10% of patients in real-world practice. Areas covered: The development of newer generations of DES, drug-coated balloons (DCB) and incre

The use of current-generation DES is associated with low rates of restenosis, target lesion revascularization, and stent thrombosis compared with early-generation DES or bare metal stents. However, major adverse cardiovascular events such as restenosis or stent thrombosis continue after one year with approved, commercially available, current. The study included 909 patients (1077 ISR lesions) distributed as follows: bare metal stent (n=388), first-generation DES (n=425), and second-generation DES (n=96), categorized into acute coronary syndrome (ACS) or non-ACS presentation mode at the time of first target lesion revascularization 2011 International Conference on Instrumentation, Communication, Information Technology and Biomedical Engineering 8-9 November 2011, Bandung, Indonesia New Generation of Medical Implants: Metallic Biodegradable Coronary Stent Hendra Hermawan1,2, Diego Mantovani2 1 Faculty of Biomedical Engineering and Health Science, Universiti Teknologi Malaysia, Malaysia (Tel : +60-7-553-6490; E-mail. Hence, the latest generation of multidetector (multisection) CT scanners, which offer a smaller voxel size, faster gantry rotation speed, and reconstruction of 64 sections per gantry rotation, provide an appealing alternative for noninvasive luminal assessment in patients with chest pain after coronary stent placement (, 12 )

Percutaneous coronary intervention of calcified lesions was associated with worse outcomes in the era of bare‐metal and first‐generation drug‐eluting stents. Data on percutaneous coronary intervention of calcified lesions with newer‐generation drug‐eluting stents are scarce Percutaneous coronary intervention (PCI) has continued to evolve, from its origins in balloon angioplasty and bare metal stent (BMS) implantation, to the development and application of contemporary drug-eluting stents (DESs). While first generation DESs significantly decreased risk of in-stent restenosis observed with BMSs, their use was complicated by late and very late stent thrombosis.

[Coronary stents]

  1. Bare metal stents (BMS) are made of nickel-titanium alloy. Drug eluting stents (DES) have drugs (eg, 1st-generation: sirolimus, paclitaxel; 2nd-generation: everolimus, zotarolimus) bonded to the metal that limit neointimal proliferation to reduce the risk of restenosis.Radioactive stents or pre-stent intracoronary radiation using radioactive pellets (brachytherapy) have not proven effective at.
  2. Stent thrombosis is a thrombotic occlusion of a coronary stent. This is usually an acute process in contrast to restenosis, which is a gradual narrowing of the stent lumen due to neointimal proliferation. Stent thrombosis often results in an acute coronary syndrome, while restenosis often results in anginal symptoms

The story of coronary stent

Coronary stents have been used for more than two decades. During this period, stent designs have been modified to improve safety in patients [].Bare metal stents (BMSs) were followed by first-generation permanent polymer drug-eluting stents (paclitaxel- and sirolimus-DESs) Second, the deliverability of first-generation drug-eluting stents could be improved. Third, although these stents are more effective than are bare metal stents in patients at high risk of restenosis, the need for reintervention is still a problem in patients with severe coronary disease, as shown in a randomised study in which individuals with complex coronary disease were given percutaneous. Most published trials fail to show a benefit from coronary stenting in patients with stable obstructive coronary artery disease. However, stent technology has evolved significantly in recent years. Implantation of drug-eluting stents (DES) is the dominant treatment strategy for patients with symptomatic coronary artery disease. However, the first-generation DES had substantial drawbacks.

Clinical Presentation and Outcomes of Coronary In-Stent

The gene, MEF2A, was discovered by methodically studying the genetic makeup of 21 members of an Iowa family plagued for generations by incidents of coronary artery disease and heart attack. Every patient in the Iowa family who experienced a heart attack had at least one coronary risk factor Subsequently, drug-eluting stents (DES) were introduced, which had the added advantage of releasing an anti-proliferative drug from the stent to reduce the neointimal proliferation, thus resulting in the reduction of the rates of in-stent restenosis. Although the first-generation DES had significantly improved outcomes over its predecessor, the. In-stent restenosis (ISR) arising in bare-metal stents and drug-eluting stents is difficult to manage. Herein, we report a case of ISR. Our patient had a history of percutaneous coronary intervention and presented with exaggerated angina symptoms despite being on antianginal medication. ISR was diagnosed with coronary angiography. In a clinical setting, it is treated with repeat. Coronary artery stents have revolutionized the field of interventional cardiology.
