Risk of new-onset atrial fibrillation after drug-eluting stent implantation in patients with stable coronary artery disease

BackgroundNew-onset atrial fibrillation (NOAF) is associated with adverse outcomes in patients with coronary artery disease (CAD). Although newer generation drug-eluting stents (NG-DESs) are more beneficial than bare-metal stents (BMSs) in reducing the risk of in-stent restenosis and revascularization, whether NG-DES implantation in patients with stable CAD reduces NOAF risk compared with BMS implantation remains unknown. MethodsThis population-based cohort study was conducted using data from Taiwan's National Health Insurance Research Database. Propensity score matching was used to select 18,423 pairs of patients with stable CAD receiving NG-DES implantation and BMS implantation with similar baseline characteristics for evaluation. A competing risk model was used to evaluate the risk of NOAF between the NG-DES and BMS groups in which death was considered a competing risk. ResultsAfter adjustment for patients' clinical variables, the use of NG-DESs was associated with a decreased risk of NOAF at 1-year follow-up (adjusted subdistribution hazard ratio [SHR] = 0.79, 95% confidence interval [CI] = 0.68–0.93, P = 0.005) compared with the use of BMSs. Similar results indicated that NG-DESs were beneficial for reducing the risk of NOAF (adjusted SHR = 0.81, 95% CI = 0.67–0.97, P = 0.020) in patients with a CHA2DS2-VASc score of ≥2. These findings were also consistent with those for patients who received dual antiplatelet therapy for an undefined duration of >1 month following stent implantation. ConclusionsOur findings suggest that NG-DESs might reduce the risk of NOAF in patients with stable CAD.

Coronary artery bypass confers intermediate-term survival benefit over percutaneous coronary intervention with new-generation stents in real-world patients with multivessel coronary artery disease, including left main disease: a retrospective analysis of 6383 patients.

The intermediate-term all-cause mortality rate of real-world patients with multivessel disease (MVD) treated with percutaneous coronary intervention (PCI) with new-generation drug-eluting stents or coronary artery bypass grafting (CABG) remains unknown. We sought to compare the intermediate-term all-cause mortality rates of real-world patients with MVD including left main stem disease, treated with CABG or PCI. All consecutive all-comer patients with MVD undergoing CABG or PCI with second/third generation drug-eluting stents from 2007 to 2015 in Harefield Hospital, UK were included in this study. The revascularization modality was based on heart team discussions. Primary outcome was all-cause mortality. Mean follow-up of the study was 3.3 years. Cox regression analysis and propensity matching were used. Of 6383 patients with MVD, 4230 underwent CABG, whereas 2153 had PCI with new-generation stents. In the CABG group, the mean age was 66.4 ± 10 years, whereas in the PCI group it was 65.3 ± 12.1 years (P < 0.001). Fewer female patients with MVD were treated with CABG than were treated with PCI (18.5% vs 20.5%; P = 0.026). There was a higher 5-year estimated survival rate among patients having CABG (88% vs 78.3%; Plog-rank < 0.001). The adjusted hazard ratio (HR) for PCI over CABG was 1.74 [95% confidence interval (CI) 1.41-2.16; P < 0.001]. A total of 653 patients having CABG and 653 having PCI were included in the propensity-matched groups. At mean follow-up, PCI was associated with a higher adjusted HR for all-cause mortality (2.18, 95% CI 1.54-3.1; P < 0.001). In this contemporary cohort of real-world patients with MVD, CABG was associated with increased intermediate-term survival compared to PCI with new-generation drug-eluting stents.

Drug-eluting or bare-metal stents for percutaneous coronary intervention: a systematic review and individual patient data meta-analysis of randomised clinical trials

New-generation drug-eluting stents (DES) have mostly been investigated in head-to-head non-inferiority trials against early-generation DES and have typically shown similar efficacy and superior safety. How the safety profile of new-generation DES compares with that of bare-metal stents (BMS) is less clear. We did an individual patient data meta-analysis of randomised clinical trials to compare outcomes after implantation of new-generation DES or BMS among patients undergoing percutaneous coronary intervention. The primary outcome was the composite of cardiac death or myocardial infarction. Data were pooled in a one-stage random-effects meta-analysis and examined at maximum follow-up and a 1-year landmark. Risk estimates are reported as hazard ratios (HRs) with 95% CIs. This study is registered in PROSPERO, number CRD42017060520. We obtained individual data for 26 616 patients in 20 randomised trials. Mean follow-up was 3·2 (SD 1·8) years. The risk of the primary outcome was reduced in DES recipients compared with BMS recipients (HR 0·84, 95% CI 0·78-0·90, p<0·001) owing to a reduced risk of myocardial infarction (0·79, 0·71-0·88, p<0·001) and a possible slight but non-significant cardiac mortality benefit (0·89, 0·78-1·01, p=0·075). All-cause death was unaffected (HR with DES 0·96, 95% CI 0·88-1·05, p=0·358), but risk was lowered for definite stent thrombosis (0·63, 0·50-0·80, p<0·001) and target-vessel revascularisation (0·55, 0·50-0·60, p<0·001). We saw a time-dependent treatment effect, with DES being associated with lower risk of the primary outcome than BMS up to 1 year after placement. While the effect was maintained in the longer term, there was no further divergence from BMS after 1 year. The performance of new-generation DES in the first year after implantation means that BMS should no longer be considered the gold standard for safety. Further development of DES technology should target improvements in clinical outcomes beyond 1 year. Bern University Hospital.

Clinical Outcomes of the Dual-Therapy CD34 Antibody-Covered Sirolimus-Eluting Stent Versus Standard Drug-Eluting Coronary Stents: A Meta-Analysis.

Coronary stent neoatherosclerosis, thrombosis, and restenosis remain significant concerns with new-generation drug-eluting stents (DES). The Dual-Therapy CD34 antibody-covered sirolimus-eluting stent [dual therapy stent (DTS)] is a sirolimus-eluting stent with CD34 antibodies immobilized on its luminal surface to capture circulating endothelial progenitor cells and promote early endothelialization. We conducted a meta-analysis to determine whether the DTS was superior to standard DES. We conducted a comprehensive search for controlled randomized and non-randomized studies. We presented data using risk ratios (95% confidence intervals) and measured heterogeneity using Higgins' I2. Five studies with a low risk of bias met the inclusion criteria, with a total of 1884 patients in the DTS and 1819 in standard DES arms. There was no difference between the 2 arms in the following 1-year outcomes: cardiac death [1% vs 0.9% RR 1.13 (95% CI 0.49-2.62) I2 = 0%], target lesion failure [6.2% vs 5.3% RR 1.12 (0.80-1.58) I2 = 0%], target lesion revascularization (TLR) [4.9% vs 3.4% RR 1.40 (0.93-2.10) I2 = 15%], target vessel failure [8.2% vs 6.1% RR 1.24 (0.75-2.04) I2 = 0%], target vessel myocardial infarction [1.1% vs 1.8% RR 0.73 (0.19-2.90) I2 = 62%] and stent thrombosis [0.4% vs 0.6% HR 0.85 (0.27-2.62) I2 = 0%]. However, compared with second-generation DES (EES and ZES), the DTS had significantly higher one-year TLR [5% vs. 3.1% RR 1.58 (1.02-2.46) P = 0.04 I2 = 0%]. One-year TLR was significantly higher in the DTS arm compared with second-generation DES. There was no difference in the other 1-year clinical outcomes compared with standard DES.

New-generation drug eluting stent vs. bare metal stent in saphenous vein graft – 1 year outcomes by a propensity score ascertainment (SVG Baltic Registry)

BackgroundData regarding the efficacy of the percutaneous coronary intervention (PCI) with new-designed drug-eluting stent (new-DES) vs. bare metal stent (BMS) of saphenous vein grafts (SVG) stenosis is scarce. The primary objective was to compare one-year clinical outcomes of PCI in stenosis of SVG using new-DES vs. BMS in a real-world population. Methods and resultsWe carried out a multi-center registry comparing new-DES with BMS in all consecutive patients undergoing PCI of SVG. The primary composite endpoint was major adverse cardiac and cerebrovascular events (MACCE) at 1 year. This observation included 792 consecutive patients (mean age 69 ± 8.9y), treated with either new-DES (n = 379, 47.9%) or BMS (n = 413, 52.1%). Among patients treated with new-DES compared with BMS, there was a lower risk of MACCE (21.4% vs. 28.3%, HR = 0.69, 95% CI 0.50–0.95, p = 0.025) as well as myocardial infarction (MI) (6.3% vs. 12.1%; HR 0.49, 95% CI 0.30–0.82, p = 0.005) at 1 year. After propensity score adjustment, the similar, significant reduction in MACCE and MI was observed in favor of new-DES (HR 0.66, 95% CI 0.46–0.96, p = 0.030; and HR 0.53, 95% CI 0.31–0.92, p = 0.020, respectively). ConclusionIn patients undergoing PCI of SVG, the use of new-DES is associated with a reduced 1-year rate of MACCE and MI compared to BMS.

7-Year Outcomes of a Randomized Trial Comparing the First-Generation Sirolimus-Eluting Stent Versus the New-Generation Everolimus-Eluting Stent: The RESET Trial

ObjectivesThe aim of this study was to compare 7-year outcomes between the first-generation sirolimus-eluting stent (SES) and the new-generation everolimus-eluting stent (EES) in a randomized clinical trial. BackgroundThere is a scarcity of very long-term (beyond 5 years) data from clinical trials investigating whether new-generation drug-eluting stents have clear clinical advantages over first-generation drug-eluting stents. MethodsRESET (Randomized Evaluation of Sirolimus-Eluting Versus Everolimus-Eluting Stent Trial) is the largest randomized trial comparing EES with SES (NCT01035450). Among a total of 3,197 patients in the original RESET population from 100 centers, the present extended 7-year follow-up study was conducted in 2,667 patients from 75 centers after excluding those patients enrolled from centers that denied participation. Complete 7-year follow-up was achieved in 91.5% of patients. ResultsThe cumulative 7-year incidence of the primary efficacy endpoint of target lesion revascularization was not significantly different between EES and SES (10.2% vs. 11.7%; hazard ratio: 0.87; 95% confidence interval: 0.68 to 1.10; p = 0.24). The risk for the primary safety endpoint of death or myocardial infarction trended lower with EES than with SES (20.6% vs. 23.6%; hazard ratio: 0.85; 95% confidence interval: 0.72 to 1.005; p = 0.06). The cumulative 7-year incidence of definite stent thrombosis was very low and similar between EES and SES (0.9% vs. 1.0%; p = 0.82). The lower risk of EES relative to SES was significant for the composite secondary endpoint of target lesion failure (13.3% vs. 18.1%; hazard ratio: 0.72; 95% confidence interval: 0.59 to 0.88; p = 0.001). ConclusionsDuring 7 years of follow-up, the risk for target lesion revascularization was not significantly different between the new-generation EES and the first-generation SES.

TCTAP A-133 Domestic New-generation Drug-eluting Stents Versus Imported New-generation Drug-eluting Stents in China

In recent years, new-generation drug-eluting stents (Gn-DESs) were domestically produced in China, but how domestic Gn-DESs perform compared to imported new-generation DESs was still unknown. A total of 7,316 consecutive cases with new-generation DESs (Gn-DESs) implantation in a single center

Effect of stent diameter in women undergoing percutaneous coronary intervention with early- and new-generation drug-eluting stents: From the WIN-DES collaboration

BackgroundThe risk of stent thrombosis (ST) or target lesion revascularization (TLR) is increased with smaller stent diameters (SD). Whether SD has a deleterious effect in women treated with early- vs. new-generation drug-eluting stents (DES) is unknown. MethodsWe pooled patient-level data from 26 randomized control trials of DES. Only women treated with DES were included. Subjects were stratified according to SD: small, SD ≤ 2.75 mm; intermediate, 2.75 mm < SD ≤ 3.25 mm; and large, SD ≥ 3.25 mm. Endpoints of interest were 3-year definite ST, TLR, major adverse cardiac events (MACE: the composite of death, myocardial infarction or TLR) and death. ResultsOf 6413 women, 2274 (35.0%) had a small SD, 2448 (38.0%) had an intermediate SD, and 1691 (26.0%) had a large SD. By multivariable analysis, stent diameter (per 0.25 mm decrease) was associated with an increased risk of TLR and ST, which was uniform in terms of magnitude and direction between early- and new-generation DES. There were no differences in MACE or death across groups. ConclusionSmall SD in women undergoing PCI is associated with an increased risk of definite ST and TLR, consistently with both early- and new-generation DES.

Outcomes with Drug-Coated Balloons in Percutaneous Coronary Intervention in Diabetic Patients.

Percutaneous coronary intervention (PCI) in patients with diabetes mellitus (DM) remains associated with inferior clinical outcomes and an increased risk of restenosis compared with non-diabetics even in the era of drug-eluting stents (DES). The outcomes with drug-coated balloons (DCBs) in diabetic patients have received limited study. We performed a meta-analysis of all studies published between January 2000 and January 2019 reporting the outcomes with DCB vs. DES after PCI of de-novo coronary lesions in diabetic patients. Outcomes included major adverse cardiovascular events (MACE), target lesion revascularization (TLR), binary restenosis by quantitative coronary angiography (QCA), and late lumen loss (LLL). Three studies with 378 patients (440 lesions) were included in the meta-analysis. During 17.3 ± 11.3 months follow-up, DCB were associated with a similar risk of MACE (OR: 0.63, 95% CI [0.36, 1.12], p = 0.11), TLR (OR: 0.51, 95% CI [0.25, 1.06] p = 0.07), binary restenosis (OR: 0.42, 95% CI [0.09, 1.92], p = 0.26), and LLL (mean difference: -0.13 mm, 95% CI [-0.41, 0.14], p = 0.34) compared with DES. In diabetic patients with de-novo coronary lesions undergoing PCI, DCBs are associated with similar outcomes compared with first-generation DES, with a signal toward potential benefit in lowering target lesion revascularization. Further randomized studies are needed to compare the newer-generation DCBs and DES in this setting.

Role of Drug-coated Balloons in Small-vessel Coronary Artery Disease

Percutaneous coronary intervention of small-vessel coronary artery disease (SVD) remains challenging due to difficulties with device delivery and high restenosis rate, even with the use of newer-generation drug-eluting stents. Drug-coated balloons represent an attractive emerging percutaneous coronary intervention option in patients with SVD. Potential advantages of drug-coated balloons in SVD include enhanced deliverability because of their small profile, avoidance of foreign-body implantation, and shorter duration of dual antiplatelet therapy.

One-year clinical outcomes between biodegradable-polymer-coated biolimus-eluting stent and durable-polymer-coated drug-eluting stents in STEMI patients with multivessel coronary artery disease undergoing culprit-only or multivessel PCI

Background and aimsThere are limited data comparing clinical outcomes among new-generation drug-eluting stents (DES) in ST-segment elevation myocardial infarction (STEMI) patients with multivessel coronary artery disease (MVD) who underwent primary percutaneous coronary intervention (PCI) with culprit-only or multivessel PCI. We investigated 1-year clinical outcomes between biodegradable-polymer (BP)-coated biolimus-eluting stent (BES) and durable-polymer (DP)-coated DES in STEMI patients with MVD who underwent two different reperfusion strategies. MethodsA total of 4255 patients were enrolled and divided into two groups, a culprit-only (n = 2571, BP- [n = 264] or DP-DES [n = 2307]) or a multivessel PCI group (n = 1684, BP- [n = 145] or DP-DES [n = 1539]). The primary endpoint was major adverse cardiac events (MACE) defined as all-cause death, recurrent myocardial infarction (re-MI), and total repeat revascularization. The secondary endpoint was the incidence of definite or probable stent thrombosis (ST). ResultsBP-BES and DP-DES showed a similar 1-year adjusted hazard ratio (HR) for MACE (culprit-only, adjusted hazard ratio [HR], 1.114; p = 0.740; multivessel, HR, 0.564; p = 0.167) and ST (culprit-only, HR, 1.110, p = 0.891; multivessel, HR, 0.375; p = 0.402). The adjusted HR for all-cause death, re-MI, and repeat revascularization were similar between the two groups. In the total population, the culprit-only PCI group showed a higher incidence of total repeat revascularization than the multivessel PCI group. ConclusionsBP-BES and DP-DES showed comparable safety and efficacy in STEMI patients with MVD who underwent primary PCI with two different reperfusion strategies during a 1-year follow-up period.

CLINICAL OUTCOMES OF NEWER-GENERATION VERSUS SECOND-GENERATION DRUG-ELUTING STENT IMPLANTATION IN PATIENTS WITH CORONARY ARTERY DISEASE: RETROSPECTIVE ANALYSIS OF REAL-WORLD DATA

Late adverse events such as very late stent thrombosis (ST) and late target lesion revascularization are still concern issues. Newer-generation drug-eluting stent (DES) is expected to reduce these events. The aim of this study was to investigate clinical outcomes in patients after newer-generation

EARLY DUAL ANTIPLATELET THERAPY DISCONTINUATION IN CANCER PATIENTS WITH NEWER GENERATION DRUG-ELUTING STENTS: A SINGLE CENTER EXPERIENCE

Newer generation drug-eluting stents (DES) may allow for early discontinuation of dual antiplatelet therapy (DAPT). DAPT duration after PCI has not been validated in cancer patients. We aimed to describe the practices and outcomes regarding DAPT duration in a cancer population with DES. We

Assessment of strut coverage of everolimus-eluting platinum chromium stent 2 weeks after implantation by optical coherence tomography.

The SYNERGY coronary stent is new-generation drug-eluting stents, which has a thin-strut platinum-chromium platform with everolimus in a biodegradable polymer applied to the abluminal surface. It would be speculated that favorable arterial healing with early strut coverage could be achieved. The present study investigated the degree of strut coverage using optical coherence tomography (OCT) 2weeks after SYNERGY implantation and clinical factors contributing to strut coverage. A total of 29 patients who underwent staged percutaneous coronary intervention (PCI) to residual lesions 2weeks after the index PCI with SYNERGY stent implantation were enrolled. At the time of staged PCI, OCT examinations of the SYNERGY stent were performed for conventional OCT analysis on both cross-sectional and strut level. SYNERGY stent showed a high level of strut coverage and apposition, and the percentage was 82.4 ± 12.4% and 96.2 ± 5.0%, respectively. The lesion complexity was significantly related to greater strut coverage on univariate analysis; however, it was found to be insignificant in multivariate analysis. Our findings suggest early arterial healing after SYNERGY stent implantation.

100.62 Ultrathin-Strut Biodegradable-Polymer Sirolimus-Eluting Stents Versus Thin-Strut Durable-Polymer Everolimus-Eluting Stents in Patients Undergoing Percutaneous Coronary Intervention: A Meta-Analysis of Individual Patient Data From Randomized Controlled Trials

Newer-generation drug-eluting stents combining biodegradable polymers with ultrathin-strut cobalt-chromium stent platforms minimize coronary vessel injury and inflammatory response. The objective of the present study was to evaluate the safety and efficacy of ultrathin-strut, biodegradable-polymer

A Review of the Ultrathin Orsiro Biodegradable Polymer Drug-eluting Stent in the Treatment of Coronary Artery Disease.

Drug-eluting stents (DES) have revolutionised the treatment of coronary artery disease (CAD) in patients undergoing percutaneous coronary intervention. In recent years, there has been a focus on a new generation of DES, such as biodegradable polymer DES (BP-DES). This novel stent platform was developed with the hope of eliminating the risk of very late stent thrombosis associated with the current gold-standard durable polymer DES (DP-DES). Ultrathin Orsiro BP-DES (Biotronik, Bülach, Switzerland) are based on a cobalt-chromium stent platform that is coated with a bioresorbable polymer coating containing sirolimus. These devices have one of the thinnest struts available in the current market and have the theoretical benefit of reducing a chronic inflammatory response in the vessel wall. In 2019, the United States Food and Drug Administration (FDA) approved the use of Orsiro BP-DES in patients with CAD based on promising results in recent landmark trials, such as BIOFLOW V and BIOSTEMI. The aim of the present review article was to discuss the history of stent technology and the continued opportunities for improvements, focusing on the potential benefits of Orsiro BP-DES.

Outcomes of New-Generation Drug-Eluting Stents in Women with Acute Myocardial Infarction.

This review discusses the outcomes of percutaneous coronary intervention (PCI) in women who experience acute myocardial infarction (AMI) and are treated with drug-eluting stents (DES). The review also describes the role of the new-generation DES compared with the early generation. Recent literature shows that the new-generation DES can be effective in women who present with AMI. Women with AMI may be undertreated and are underrepresented in studies of AMI. Recently, it has been shown that the newer generation DES are effective and beneficial in women with AMI, similar to men. As further generations of DES are created, the future appears promising for continued advancements in women's cardiovascular health.

New-generation drug-eluting stents for left main coronary artery disease according to the EXCEL trial enrollment criteria: Insights from the all-comers, international, multicenter DELTA-2 registry

BackgroundPercutaneous coronary intervention (PCI) has been established as an alternative treatment option to coronary artery by-pass graft (CABG) surgery in patients with left main coronary artery disease (LMCAD). Whether the findings of randomized controlled trials are applicable to a real-world patient population is unclear. MethodsWe compared the outcomes of PCI with new-generation DES in the all-comer, international, multicenter DELTA-2 registry retrospectively evaluating mid-term clinical outcomes with the historical CABG cohort enrolled in the DELTA-1 registry according to the EXCEL key inclusion or exclusion criteria. The primary endpoint was the composite of death, myocardial infarction, or stroke at the median time of follow-up time of 501 days. The consistency of the effect of DELTA-2 PCI versus DELTA-1 CABG according to the EXCEL enrollment criteria was tested using propensity score-adjusted Cox regression models. ResultsOut of 3986 patients enrolled in the DELTA-2 PCI registry, 2418 were EXCEL candidates and 1568 were not EXCEL candidates. The occurrence of the primary endpoint was higher among non-EXCEL candidates compared with EXCEL candidates (15.4% vs. 6.9%; hazard ratio 2.52; 95% confidence interval 2.00–3.16; p < 0.001). Among 901 patients enrolled in the historical DELTA-1 CABG cohort, 471 were EXCEL candidates and 430 were not EXCEL candidates. When comparing the DELTA-2 PCI with the DELTA-1 CABG cohort, the occurrence of the primary endpoint was lower in the PCI group compared with the historical CABG cohort among EXCEL candidates (6.9% vs. 10.7%; adjusted hazard ratio: 0.65; 95% confidence interval: 0.45–0.92), while no significant difference was observed among non-EXCEL candidates (15.4% vs. 12.5%; adjusted hazard ratio: 0.94; 95% confidence interval: 0.67–1.33) with evidence of statistical interaction (adjusted interaction p-value = 0.002). ConclusionsIn a real-world population, PCI can be selected more favorably as an alternative to CABG in patients fulfilling the enrollment criteria of the EXCEL trial.

Dual Antiplatelet Therapy Duration Determines Outcome After 2- But Not 1-Stent Strategy in Left Main Bifurcation Percutaneous Coronary Intervention

ObjectivesThe aim of this study was to investigate clinical outcomes after left main coronary artery (LM) bifurcation percutaneous coronary intervention (PCI) and the impact of the duration of dual antiplatelet therapy (DAPT) according to treatment strategy. BackgroundThere are limited data regarding the optimal PCI strategy for LM bifurcation lesions with new-generation drug-eluting stents. MethodsA patient-level pooled analysis of 5 nationwide multicenter registries was performed. Rates of target lesion failure, thrombotic adverse cardiovascular events, and their individual components at 3-year were analyzed. Subgroup analysis according to DAPT duration was performed. ResultsFrom 13,172 patients undergoing PCI with new-generation drug-eluting stents, a total of 700 patients were treated for LM bifurcation lesions, 567 with a 1-stent strategy and 133 with a 2-stent strategy. Rates of target lesion failure and target lesion revascularization were higher in the 2-stent group, driven mainly by complex lesion profiles. Risks for thrombotic adverse cardiovascular events and its components were comparable between the 2 strategies. Subgroup analysis showed that risks for target lesion failure and thrombotic adverse cardiovascular events in the 2-stent group were significantly higher than in the 1-stent group in those with DAPT interruption <1 year, while they were similar in those receiving DAPT maintenance ≥1 year. ConclusionsUp to 20% of patients who underwent LM bifurcation PCI eventually required a 2-stent strategy, which was as safe as a 1-stent strategy with the use of new-generation drug-eluting stents. Careful pre-emptive case selection as well as prolonged DAPT may be necessary when considering a 2-stent strategy in LM PCI given its higher rate of repeat revascularization and lesion failure than the 1-stent approach.

The EluNIRTM Ridaforolimus Eluting Coronary Stent System

ABSTRACTIntroduction: First-generation drug-eluting stents (DES) were developed and indeed proved their superiority compared to bare-metal stent in minimizing neo-intimal hyperplasia and in-stent restenosis (ISR), overall, reducing target vessel revascularization (TVR). Newer-generation DES are characterized by thinner struts, more biocompatible and either durable, biodegradable or polymer-free surfaces, better device profile and refined drug elution.Area covered: The EluNIRTM (Medinol, Tel Aviv, Israel) Ridaforolimus Eluting Coronary Stent System is a new DES with unique properties. In this review, we highlight the special characteristics of the stent and summarize relevant clinical data. The EluNIRTM was studied in two clinical trials, the NIREUS trial and the larger, pivotal, BIONICS trial. These trials collectively provide data on the safety, performance, and efficacy of the device.Expert commentary: The newly FDA-approved EluNIRTM stent features an elastomeric durable polymer which elutes a novel drug, Ridaforolimus. The stent has thin struts with variable widths and a delivery catheter with a spring tip. These characteristics may explain the good angiographic and clinical results of this stent, which were noninferior to the FDA-approved Medtronic ResoluteTM stent DES.
