Overview of Abluminus DES+ABLUMINUS DES+ (Designed to treat Diabetic Patients)Abluminus DES+ is a Cobalt Chromium Stent System specially designed for diabetic patients and CE approved for diabetic and AMI Indication. It is an abluminally coated Sirolimus Drug Eluting Stent. The drug is coated on both the stent and the exposed parts of the balloon.
DIABETES MELLITUS: AN UNMET CLINICAL NEEDDiabetes mellitus (DM) is a major public health problem.415 million people worldwide, or one in eleven adults are estimated to have DM. If the current trend in diabetes prevalence continues, by 2040 some 642 million people, or one adult in ten, will have diabetes [1].
Patients with DM are more a�ected by Coronary Artery Disease (CAD) and when treated by Percutaneous Coronary Interven-tion (PCI) with stent implantation they remain at higher risk for in-stent restenosis and adverse cardiovascular events [2-4]. The diabetic patient presents a well-known pattern of CAD – extensive atherosclerosis, a greater number of significant stenosis, longer lesions and more di�use and distal disease [5]. The presence of DM (particularly insulin-treated DM) has been a consis-tent, independent predictor of in-stent restenosis [6].
Although second-generation DES seem to provide superior safety and e�cacy when compared with first-generation DES, late adverse events remain a problem, presumably because of a persistent inflammatory response in the arterial wall. It has been speculated that the use of stents with biodegradable polymers or without a polymer may avoid late events caused by the chronic inflammation related to its presence [7].
Multiple factors lead to diabetic patients having an impaired endothelial function. These include hyperglycaemia, excess of free fatty acids and insulin resistance. The increased production of tissue factor and plasminogen activator inhibitor-1 create a pro-thrombotic environment that, together with the increased ability of platelets to aggregate, leads to an increased propensi-ty for thrombotic complications in diabetic patients. Thus, it is not unexpected that DM in combination with premature discontinuation of antiplatelet therapy; bifurcation lesions, low ejection fraction and renal failure has been identified as an independent predictor of late thrombotic events after DES implantation [8].
Patients with DM represent 20-30% of all PCI performed. Furthermore, they represent a very complex subgroup of patients since their coronary artery disease is more extensive. Over the years, stent technology has been developed and clinical outcomes have improved mainly in non-diabetic patients. In diabetic patients we continue to struggle to o�er them the best results with PCI. In addition, diabetic patients with multi-vessel disease still benefit most with coronary artery bypass graft surgery. With this, Abluminus DES is designed to treat diabetic patients with envisolution technology.
Envisolution TechnologyAN ENHANCED DRUG DELIVERY TECHNOLOGY WITH HOMOGENEOUS DRUG COATING
ABLUMINAL COATING Facilitate mono directional drug release and less systemic exposure of drug leading to faster re-endothelialisation
FUSION COATINGCoating on the stent and exposed parts of the balloon facilitate homogenous drug delivery which address di�used proliferative disease and focal restenosis
EDGE COATING The additional 0.5mm coating on the edge of the balloon which addresses the edge restenosis
BIODEGRADABLE FILM
The formation of circular film with biodegradable polymer facilitate maximum drug delivery in blood wet conditions
Abluminus DES+, addresses the nature of the diabetic lesion in the patients and properly provides thedesired treatment.

en-ABL 1 STUDY
INTRODUCTION AND OBJECTIVES
The Abluminus DES+, a novel Abluminal surface coating on stent and exposed parts of balloon in pre-crimped condition with Sirolimus. We sought to investigate the performance and e�cacy of this novel DES technology in patients treated in daily clinical practice.
METHOD
The en-ABL 1 FIM trial was prospective, single-center, non-randomized, single-arm, first-in human evaluation of safety, feasibility and performance of ABLUMINUS DES+. Inclusion criteria were without limitation to number of lesions, vessels and lesion length as real-world population. Clinical follow-up was performed at 1, 6, 12, 24 and 36 months. All patients were assigned for angiographic re-evaluation at 6 months, and the primary endpoint was in-stent Late Lumen Loss (LLL), as determined by independent Quantitative Coronary Angiography (QCA) analysis.
RESULTS
A total 40 patients (56 lesions) were enrolled between March 2012 and August 2012. Mean age was 54.35±10.51 years, 17(42.5%) were diabetics, 25(62.5%) were hypertension and 11(47.5) had a previous myocardial infraction (MI). Baseline median [25%, 75% interquartile range] lesion length, reference vessel diameter, MLD and % diameter stenosis were respectively 14.9[10.4,23.0] mm, 2.33[2.09,2.75] mm, 0.75 [0.45,0.98] mm and 67.4 [61.2,78.8]. Average stent per patient, stent length, stent diameter and inflation time were 1.40, 27.35 mm, 2.87 mm and 28 seconds respectively. At 6-months angiographic follow-up (39/40), median in-stent LLL was 0.14 [0.06,0.29] and of total lesions 3.7% binary restenosis was observed. Clinical follow-up MACE (composite of death, MI and target lesion revascularization) was 2.5% at 12 months follow-up. There was no stent thrombosis (ST) event recorded up to 12 months follow-up. There was one cardiac death and no ST reported through 36 month follow-up.
CONCLUSION
A novel abluminal coated Sirolimus eluting stent Abluminus DES+ in en-ABL 1 first-in-human study demonstrated excellent performance (100% procedural success), e�cacy with optimum LLL at 7 months despite complex lesions and small vessels and low MACE at 36 months with no event of stent thrombosis.

Low incidences of MACE and ST at long-term follow-up indicates that ABLUMINUS DES+ may have encouraging safety and e�cacy in real-world unselected patients with CAD.
Logistic Regression performed for confounding factors reveals that small vessels, MVD, overlapping of stent and LM lesion had direct impact on the e�cacy and safety of the device.
Conclusion
Subgroup analysis: MACE at 1 year
The results of exploratory subgroup analysis of the primary endpoint are shown here. This analysis suggested there was no significant di�erence in MACE across all di�erent subgroups except small vessel, MVD and overlapping DES.

DIABETES MELLITUS PROMISING CLINICAL OUTCOMES IN CHALLENGING SUBGROUP
Diabetics are prone to CAD along with other conditions. Patients with CAD and DM undergoing PCI are at significantly increased risk for short and long term adverse clinical outcomes. The underlying mechanism is due to the more di�use and accelerated form of atherosclerosis and endothelial dysfunction which lead to di�used coronary lesions, small vessel disease, multi-vessel involvement, larger plaque burden as well as higher incidence of left main and ostial lesions.
Overall, 2,500 consecutive patients treated with ABLUMINUS DES were enrolled in the prospective, multi-centre, real-world “en-ABL e-Registry” and analysed according to the diagnosis of DM (859 patients) and insulin dependency (ID or NON-ID): Non-DM (1641 patients), IDDM: Insulin Dependent DM (138 patients), NIDDM: Non-Insulin Dependent DM (721 patients).

ACUTE MYOCARDIALINFARCTIONPROMISING CLINICAL OUTCOMES IN CHALLENGING SUBGROUP
The e�cacy and safety of DES in the treatment of coronary artery disease is well established. Restenosis rates have dramatically decreased for CAD indications. Despite these results, the concern for increased (late) stent thrombosis is still present. This finding may be due to delayed vascular healing after DES implantation probably as a result of drug and/or polymer reaction. Late coronary endothelial dysfunction after DES implantation has been reported previously. Because AMI presents the highest possible thrombotic coronary lesions, DES implantation during primary percutaneous coronary intervention (PCI) for AMI is still not advocated by many interventional cardiologists. However, even in this challenging population, the use of DES has increased over the last few years. Therefore, we aimed to evaluate the safety and e�cacy of a novel Abluminus DES in patients with AMI.
Total of 2,500 patients were enrolled in en-ABL e-Registry and among them 999 patients were having AMI and 1,501 Non-AMI.

The analysis suggests that ABLUMINUS DES+ is safe and e�ective in treating patients with AMI through 2 years. A significant di�erence was found between AMI and Non-AMI cohorts in TV-MI, TLR/TVR and total ST. Significant di�erence suggests that AMI had impact on the performance of ABLUMINUS DES although for the AMI patients MACE rates and other parameters are satisfactory.

en-ABL LM STUDY
ABLUMINUS DES+ IN UNPROTECTED LEFT MAIN: SINGLE CENTER EUROPEAN DATA
AIM: We have studied the 3-6-12-24-36 months clinical performance from the ultimate generation sirolimus eluting stent deployment Abluminus DES+ in patients with unprotected left main critical lesion. The peculiarity of the stent lies in the sirolimus coating technology which takes place after stent is crimped on the balloon. Total 24 patients with stenosis in left main coronary artery have been clinically and retrospectively evaluated.
METHODS: Patients undergoing left main angioplasty (24) with Abluminus DES+ stent implantation were clinically evaluated at regular intervals in order to evaluate any new symptoms that could make it necessary to perform a new coronary angiography. The target lesion of the angioplasty was the unprotected left main, either in the case it was limited to the LM ostium or in the case it involved the LAD-CFX bifurcation. Primary end point was represented by major adverse cardiac events MACE (composite of cardiac death, target vessel myocardial infarction (TV-MI), and target lesion/vessel revascularization) and definite or probable stent thrombosis.
RESULTS: The population in the study was represented by 70.8% of male patients with an average age of 65.5 years and only 8% of cases presenting at the Emergency Room with ST elevation myocardial infarction due to LM total occlusion. Evaluating the dual antiplatelet therapy, we observed that 58.4% of the patients were treated with Clopidogrel 75 mg and Aspirin 100 mg, 41.6% with Ticagrelor 90 mg bid and Aspirin 100 mg, no patient with Prasugrel in association with Aspirin. 83 .3% of the patients presented right dominance, 65% of them with RCA critical stenosis and 23% of these with RCA total occlusion. LM lesions had an average length of 13 mm and all cases with the presence of TIMI flow 3 in baseline. After pre-dilatation, performed in 83% (20 pts.) of the patients with semi-compliant balloon 2.67 mm mean calibre, median 2.75 and mean length 14.24 mm (median 15 mm), Abluminus DES+ was implanted with a mean diameter of 3.77 mm and median 4.00 mm with mean length of 16.5 mm (median 16). Post-dilatation involved almost all patients (95 .8%, 23 pts) with a mean and median balloon size of 4 .00 mm, mean length of 9.9 mm and a median length of 11 mm.
In about 50% of cases IVUS was performed to confirm the already well angiographic-defined result. We have also evaluated the duration of the procedure and X -rays exposure which were respectively an average of 24 and 82 minutes. Procedural success was achieved in 100% of patients, no patient showed signs and/or symptoms in the 24 hours post the procedure that could be referred to periprocedural myocardial infarction.
The 36-month follow-up was achieved in all the treated patients (24) without any adverse events.
CONCLUSION: This study demonstrated the safety and e�cacy of Abluminus DES+, an ultimate generation sirolimus drug eluting stent, in the treatment of critical lesions of the unprotected left main. We can therefore state that, due to its peculiarities in coating technology, Abluminus DES+ is an excellent treatment strategy also for most complex coronary lesions.
