Abstract Background/Introduction The novel thin composite-wire strut zotarolimus-eluting stent (ZES) is a drug-eluting stent that is frequently used for treating patients with obstructive coronary artery disease, but so far no clinical outcome data have been published in patients with diabetes. In all-comer patients, the BIONYX trial (NCT02508714) has established non-inferiority of the ZES versus the ultrathin strut biodegradable-polymer sirolimus-eluting stent (SES) regarding the primary composite endpoint of target vessel failure at 1 year follow-up. Purpose To assess in patients with diabetes, the 2-year safety and efficacy of the current generation thin composite-wire strut ZES, compared to the ultrathin strut SES. Methods In the international, multicentre BIONYX trial, randomisation was stratified for sex and the presence of diabetes mellitus. We performed a prespecified subgroup analysis of patients with diabetes. The main endpoint target vessel failure was a composite of safety and efficacy, consisting of cardiac death, target vessel-related myocardial infarction or clinically indicated target vessel revascularisation. Secondary endpoints, such as target lesion revascularisation and stent thrombosis were also assessed. Results A total of 510/2488 (20.5%) BIONYX trial participants had diabetes, and were therefore included in this analysis. Patients were on average 66.4±10.3 years old, and 28.6% were female. Most participants presented with acute coronary syndromes (65.1%), and 182/510 (35.7%) patients were insulin dependent. Two-year follow up was available in 500 of 510 (98.0%) patients. Target vessel failure occurred in 31/260 (12.2%) patients assigned to ZES versus 26/250 (10.7%) patients assigned to SES (HR 1.14, 95%-CI 0.68–1.92; P-logrank=0.63). Kaplan Meier curves of target vessel failure are displayed in Figure 1. There were no significant between-stent differences in the individual components of this endpoint. Target lesion revascularisation occurred in 15/260 (6.0%) patients treated with ZES versus 9/250 (3.7%) patients treated with SES (HR 1.61, 95%-CI 0.71–3.68; P-logrank=0.25). Definite stent thrombosis was an infrequent event and did not differ significantly between stent-arms (0.4% vs. 1.2%; HR 0.32, 95%-CI 0.03–3.06; P-logrank=0.30). Conclusion In patients with diabetes, the novel thin composite-wire strut durable polymer ZES was similarly safe and efficacious as compared to the ultrathin cobalt-chromium strut biodegradable-polymer SES at 2-year follow-up.

Abstract Background and purpose Supraflex is a sirolimus-eluting stent with a biodegradable polymeric coating and 60um ultra-thin struts. In the TALENT study, we found the Supraflex stent was non-inferior to the Xience stent for a device-oriented composite endpoint (DOCE, defined as cardiac death, target-vessel myocardial infarction, or clinically indicated target lesion revascularisation) at 12 months in an all-comer population. Additionally, per-protocol analysis showed a significantly lower clinically indicated target lesion revascularisation (CI-TLR) in the Supraflex group than in the Xience group. We now present the 2-year follow-up results. Methods The TALENT study was a prospective, randomised, single-blind, multicentre study across 23 centres in Europe. Eligible participants underwent percutaneous coronary intervention in an all-comers fashion in vessels of 2.25–4.5 mm. Patients were randomized (1:1) to implantation of either Supraflex or Xience (NCT02870140). Results Between October 21, 2016 and July 3, 2017, 720 patients with 1046 lesions were randomly assigned to Supraflex, and 715 patients with 1030 lesions to Xience. At 24 months, DOCE had occurred in 49 patients (6.9%) in the Supraflex group and in 56 patients (7.9%) in the Xience group (absolute difference −1.0% [95% CI: −3.7 to 1.7], Plog-rank=0.491). Per-protocol analysis at 24 months showed CI-TLR occurred in 21 and 30 patients in the Supraflex and Xience, respectively (3.3% versus 4.5%, absolute difference −1.2%, [95% CI: −3.3 to 0.9], Plog-rank=0.267). Conclusion In an all-comer population, at 2-year follow-up, the use of Supraflex stent was at least as safe and efficacious as Xience stent. However, the significantly lower rate of CI-TLR shown in patients treated with Supraflex at 1-year was no longer retained in the 2-year results. Whether theoretical advantage of ultra-thin strut drug eluting stents Supraflex can translate into clinical benefit or not will be further elucidated through a total of 3 years of follow-up.

Introduction: To evaluate the efficacy/safety profile of the Abluminus DES+ over 2-years follow-up in the "real-world" scenario in diabetics as compared to non-diabetics. Methods: In prospective, all-comers, open-label registry conducted at 31 sites, patients were analyzed for 1 & 2-year outcomes with the primary endpoint defined as 3P-MACE of CV death, target vessel related myocardial infarction (TV-MI), ischemia-driven target lesion revascularization (TLR)/target vessel revascularization (TVR) apart from Stent thrombosis (ST). Results: Of 2500 patients of PCI with 3286 Abluminus-DES+, 1641 (65.64%) were non-diabetics while859 (34.36%) were diabetics. The 3-P MACE for the cohort at 1 & 2 years were 2.9%, and 3.16%; TLR/TVR - 1.4% at both the intervals for 2493 patients at 2 yrs. follow-up. TV-MI & ST were 0.36% and0.56% at 1st and 2nd year respectively. The 3P-MACE was lower in non-diabetics at 1 & 2 years (2.3%vs 4.2%; 2.4% vs 4.7% respectively). For components of MACE, CV mortality (0.9 vs 1.9% at 1 yr ; 1.0vs 2.1% at 2 years) was significant (P < 0.05) while TLR (1.1 vs 1.9% at 1 yr. & 1.1 vs 2.1% at 2 yrs.) and TV-MI (0.9 vs 1.9% at 1 yr. & 1 vs 2.1% at 2 years) were similar for diabetics and non-diabetics so was ST (P > 0.05). Conclusion: Abluminus-DES+ showed excellent 2-year safety and efficacy with low 3-P MACE which was higher in diabetics driven by higher CV death but similar TLR, TV-MI and ST.

Abstract Background Patients with diabetes mellitus (DM) remain at higher risk for adverse events after percutaneous coronary intervention (PCI) compared with non-diabetic individuals. Among available drug-eluting stents (DES), thin-strut durable polymer everolimus-eluting stents (DP-EES) were shown to provide the best safety and efficacy profile in diabetics. Whether biodegradable polymer DES provide additional long-term clinical benefit compared with DP-EES among diabetic patients remains uncertain. Purpose To compare the long-term performance of ultrathin-strut biodegradable polymer sirolimus-eluting stents (BP-SES) versus DP-EES for PCI in patients with insulin-requiring and non-insulin-requiring DM. Methods We performed a prespecified subgroup analysis of the randomized, multicenter, non-inferiority BIOSCIENCE trial (NCT01443104). Patients with stable coronary artery disease or acute coronary syndrome were randomly assigned to treatment with ultrathin-strut BP-SES or thin-strut DP-EES. Patients were further divided according to diabetic status. The primary endpoint was target lesion failure (TLF), a composite of cardiac death, target-vessel myocardial infarction (MI) and clinically-indicated target lesion revascularization (TLR), within 12 months. Results Among 2'119 patients enrolled between March 2012 and May 2013, 486 (22.9%) presented with DM (insulin-requiring, 33.1%). Compared with non-diabetics, patients with DM were older and had a greater baseline cardiac risk profile, including higher prevalence of hypertension, hypercholesterolaemia, peripheral artery disease, chronic renal failure and prior PCI, coronary artery bypass graft surgery, or stroke. At 5 years, TLF occurred similarly in 74 patients (cumulative incidence, 31.0%) treated with BP-SES and 57 patients (25.8%) treated with DP-EES (RR 1.23; 95% CI 0.87–1.73; p=0.24) in diabetics, and in 124 patients (16.8%) treated with BP-SES and 132 patients (16.8%) treated with DP-EES (RR 0.98; 95% CI 0.77–1.26; p=0.90) in non-diabetics (p for interaction=0.31). Cumulative incidences of cardiac death (14.9% vs. 9.5%; p=0.10), target-vessel MI (11.4% vs. 11.0%; p=0.81), clinically-indicated TLR (16.9% vs. 15.8%; p=0.68), and definite thrombosis (3.0% vs. 2.5%; p=0.63) at 5 years were similar among diabetic patients treated with ultrathin-strut BP-SES or thin-strut DP-EES. Overall, there was no interaction between diabetic status and treatment effect of BP-SES versus DP-EES. Conclusion In a prespecified subgroup analysis of the BIOSCIENCE trial, we found no difference in clinical outcomes throughout five years between diabetic patients treated with ultrathin-strut BP-SES or thin-strut DP-EES.

Abstract Background Diabetes mellitus is a risk for increased incidence of adverse clinical events after percutaneous coronary intervention. However, the difference in the incidence of adverse clinical events according to stent type in patients with diabetes remains to be elucidated. In the present study, we aimed to compare the clinical outcomes between patients treated with the biodegradable polymer sirolimus-eluting stents (BP-SES) and the durable polymer everolimus-eluting stents (DP-EES) among patients with diabetes. Methods Among 631 lesions in 510 consecutive patients treated with either BP-SES or DP-EES, 165 lesions in 141 patients with diabetes mellitus and stable angina pectoris were identified and classified into the BP-SES group (48 lesions in 44 patients) and the DP-EES group (117 lesions in 100 patients). The incidence of adverse clinical events after stent implantation was compared between the 2 groups. Results There was no significant difference in the prevalence of conventional risk factors, lesion characteristics, and procedural characteristics between the 2 groups. During median 386 [334–472] days follow-up, the incidence of target lesion revascularization (11.4 vs. 2.0%, p = 0.003) and device-oriented clinical endpoint (13.6 vs. 6.0%, p = 0.035) in the BP-SES group was significantly greater than that in the DP-EES group. A univariate model demonstrated that the BP-SES usage was significantly associated with the higher incidence of target lesion revascularization (odds ratio, 6.686; 95% confidence interval, 1.234–36.217; p = 0.028). Conclusion BP-SES was associated with the greater incidence of TLR than the DP-EES in patients with diabetes mellitus. Further studies with larger cohorts and longer follow-up are required to confirm the present results.

We have investigated the role of drug-eluting stents on patency rates after treatment of focal infrapopliteal lesions in patients with intermittent claudication and critical limb ischemia. Reports indicate that drug-eluting stents reduce the risk of restenosis after percutaneous infrapopliteal artery revascularization. A Pub Med, EMBASE, Cochrane database review search of non-randomized studies investigating patency rates, target lesion revascularisation rates, limb salvage rates and mortality rates in an up to 3-year follow-up period after drug-eluting stent placement was conducted. In addition, preliminary results of randomized studies comparing drug-eluting stents with bare-metal stents and plain balloon angioplasty in treatment of focal infrapopliteal lesions were included in this review. A total of 1039 patients from 10 non-randomized and randomized studies were included. Most commonly used drug-eluting stents were sirolimus-eluting. The mean follow-up period was 12.6 (range 8 - 24). The mean 1-year primary patency rate was 86 ± 5 %. The mean target lesion revascularization rate and limb salvage rate was 9.9 ± 5 % and 96.6 %±4 %, respectively. Results from non-randomized and preliminary results from prospective, randomized trials show a significant advantage for drug-eluting stents in comparison to plain balloon angioplasty and bare-metal stents concerning target lesion patency and in parts target lesion revascularisation. No trial reveals an advantage for drug-eluting stents with regard to limb salvage and mortality.

Abstract Background Newest generation drug-eluting stents (DES) combining ultrathin cobalt chromium platforms with biodegradable polymers may reduce target lesion failure (TLF) as compared to second generation DES among patients with acute coronary syndrome (ACS). While previous studies indicated a potential benefit within the first two years after percutaneous coronary intervention (PCI), it remains uncertain whether the clinical benefit persists after complete degradation of the polymer coating. Purpose To compare the long-term effects of ultrathin-strut biodegradable polymer sirolimus-eluting stents (BP-SES) versus thin-strut durable polymer everolimus-eluting stents (DP-EES) for PCI in patients with ACS. Methods We performed a subgroup analysis of ACS patients included into the BIOSCIENCE trial (NCT01443104), a randomized trial comparing BP-SES with DP-EES. The primary endpoint of the present post-hoc analysis was TLF, a composite of cardiac death, target vessel myocardial infarction (MI) and clinically indicated target lesion revascularization (TLR), at 5 years. Results Among 2,119 patients enrolled between March 2012 and May 2013, 1,131 (53%) presented with ACS (ST-segment elevation myocardial infarction, 36%). Compared to patients with stable CAD, ACS patients were younger, had a lower baseline cardiac risk profile, including a lower prevalence of hypertension, hypercholesterolaemia, diabetes mellitus, and peripheral artery disease, and had a greater incidence of previous revascularization procedures. At 5 years, TLF occurred similarly in 89 patients (cumulative incidence, 16.9%) treated with BP-SES and 85 patients (16.0%) treated with DP-EES (RR 1.04; 95% CI 0.78–1.41; p=0.78) in patients with ACS, and in 109 patients (24.1%) treated with BP-SES and 104 patients (21.8%) treated with DP-EES (RR 1.11; 95% CI 0.85–1.45; p=0.46) in stable CAD patients (p for interaction=0.77) (Figure 1, Panel A). Cumulative incidences of cardiac death (8% vs. 7%; p=0.66), target vessel MI (5.2% vs. 5.8%; p=0.66), clinically indicated TLR (8.9% vs. 8.3%; p=0.63) (Figure 1, Panel B-D), and definite thrombosis (1.4% vs. 1.0%; p=0.57) at 5 years were similar among ACS patients treated with ultrathin-strut BP-SES or thin-strut DP-EES. Overall, there was no interaction between clinical presentation and treatment effect of BP-SES versus DP-EES. Conclusion In a subgroup analysis of the BIOSCIENCE trial, we found no difference in long-term clinical outcomes between ACS patients treated with ultrathin-strut BP-SES or thin-strut DP-EES at five years.

Abstract Background The AngioSculpt X (Spectranetics) is a novel paclitaxel-coated scoring balloon with encouraging preliminary data for the treatment of in-stent restenosis or de novo complex lesions. Purpose To assess the safety and efficacy of real-world patients with in-stent restenosis (ISR) or de novo complex lesions (vessels &lt;2.5 mm, calcified lesions, bifurcation lesions...) treated with the novel paclitaxel-coated scoring balloon. Methods A “real-world”, prospective registry from two centers was performed including consecutive patients presenting with ISR or de novo complex lesions and treated with AngioSculpt X. Their clinical data were prospectively registered. Major adverse cardiac events (MACE) were defined as a composite of cardiac death, stent thrombosis, nonfatal myocardial infarction, target lesion revascularization (TLR) and target vessel revascularization (TVR). Results Overall, 87 real-world patients and 93 lesions (73% male, 68±10 years, 46% smoker, 83% hypertensive, 62% diabetic, 71% hyperlipidemic, 35% LVEF &lt;60% impairment) were enrolled in the study. Clinical presentation was stable angina in 19%, unstable angina in 33%, NSTEMI in 29% and STEMI in 5%. Radial access account 84%. The median fluoroscopy time was 17 (IQ range 10,0 - 37.5) min. De novo complex lesions were treated in 35% (n=32) while ISR in 63% (n=57), (Prior BMS 19%; Sirolimus DES 9%; Everolimus DES 26%; Biolimus/Anfilimus DES 20%; Zotarolimus DES 26%) with a median time to ISR of 3.6 (IQ range 1.1 - 10.7) years. Total stent length was 28±18 mm, with an overlap spot affected in 18%, and 27% had &gt;1 treatment for ISR. The most frequent artery treated was left anterior descending (41%) followed by left circumflex (35%) and right coronary artery (17%). Quantitative coronary angiography reference diameter of lesions was 2.7±0.5 mm and length 9.0±4.8 mm, with a % stenosis of 75±20. Predilatation/postdilatation was performed in 60/24% respectively. Device diameter was 2.9±0.4 mm and length 13.6±3.9 mm, deployed at 16±3 atmospheres, with an inflation time of 33±16 seconds. The balloon/artery ratio was 0.99±0.03. Crossover was decided on 18 cases (19%) due to remaining intimal flap, but the success rate (residual stenosis &lt;30%) was 100%. Intracoronary imaging technique was performed in 12% (OCT=7, IVUS=4). At 7±6 month follow-up, there were 10 MACE (cardiac death=1, nonfatal myocardial infarction =4, TLR=4 and TVR=1). Conclusions Paclitaxel-coated scoring balloon offers a safe and valuable treatment option for ISR and de novo complex lesions. Funding Acknowledgement Type of funding source: Public hospital(s).

Multiple endovascular management of direct carotid cavernous fistula (CCF) has been widely accepted as a treatment option. Embolization of the fistula with detachable balloons or thrombogenic coil-based occlusion has been the main choice to treat direct CCF, with good safety and efficacy. This study investigated the safety and efficacy of embolization of direct CCF with the novel double-balloon technique. A retrospective review of a prospective database on cerebral vascular disease was performed. We identified a total of five patients presenting with high-flow direct CCF. All patients were managed with transarterial embolization with the novel double-balloon technique. Three of the five patients were treated with two detachable balloons, and a completely occluded fistula with preservation of the internal carotid artery was achieved. Of the remaining two patients treated with more detachable balloons, one patient achieved a perfect outcome and the other one suffered from recurrent fistula due to balloon migration 3 weeks after embolization. During a follow-up period of 12–18 months, no symptoms reoccurred in any patient. Thus, the double-balloon treatment may be a promising method for CCF complete occlusion. This novel technique may bring more benefits in the following two cases: 1). A single inflated detachable balloon fails to completely occlude the CCF, which causing the next balloon can not pass into the fistula. 2). A giant CCF needs more balloons for fistula embolization.

Abstract Background Several studies compared everolimus-eluting bioresorbable scaffolds (EE-BRS) with everolimus-eluting stents (EES), but only few assessed these devices in patients with diabetes mellitus. Aim To evaluate the safety and efficacy outcomes of all-comer patients with diabetes mellitus up to 2 years after treatment with EE-BRS or EES. Methods We performed a post hoc pooled analysis of patient-level data in diabetic patients who were treated with EE-BRS or EES in 3 prospective clinical trials: The ABSORB DM Benelux Study (NTR5447), TWENTE (NTR1256/NCT01066650) and DUTCH PEERS (NTR2413/NCT01331707). Primary endpoint of the analysis was target lesion failure (TLF): a composite of cardiac death, target vessel myocardial infarction or clinically driven target lesion revascularization. Secondary endpoints included major adverse cardiac events (MACE): a composite of all-cause death, any myocardial infarction or clinically driven target vessel revascularization, as well as definite or probable device thrombosis (ST). Results A total of 499 diabetic patients were assessed, of whom 150 received EE-BRS and 249 received EES. Total available follow-up was 222.6 patient years (PY) in the EE-BRS and 464.9 PY in the EES group. The adverse events rates were similar in both treatment groups for TLF (7.2 vs. 5.2 events per 100 PY, p = 0.39; adjusted hazard ratio (HR) = 1.48 (95% confidence interval (CI): 0.77–2.87), p = 0.24), MACE (9.1 vs. 8.3 per 100 PY, p = 0.83; adjusted HR = 1.23 (95% CI: 0.70–2.17), p = 0.47), and ST (0.9 vs. 0.6 per 100 PY, p > 0.99). Conclusion In this patient-level pooled analysis of patients with diabetes mellitus from 3 clinical trials, EE-BRS showed clinical outcomes that were quite similar to EES.
