Anatol J Cardiol 2024; 28:142-149. [PMID: 38419511 PMCID: PMC10918283 DOI: 10.14744/anatoljcardiol.2023.3801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 12/12/2023] [Indexed: 03/02/2024] Open
Abstract
BACKGROUND Supraflex (Sahajanand Medical Technologies Limited, Surat, India) is a new-generation, biodegradable polymer-coated sirolimus-eluting stent (SES) designed on an ultrathin (60 µm) cobalt-chromium platform with a flexible 'S-link.' The S-FLEX Slovakia registry aimed to assess the safety and effectiveness of Supraflex SES in an all-comers population, with a subgroup of diabetic patients. METHODS This was a prospective, observational, multi-center, post-market registry conducted between February 2018 and May 2019. All consecutive patients with symptomatic coronary artery disease scheduled for percutaneous coronary intervention with Supraflex SES were enrolled. The primary endpoint was target lesion failure (TLF), defined as a composite of cardiac death, target vessel myocardial infarction (TV-MI), or clinically indicated target lesion revascularization (CI-TLR) by percutaneous or surgical methods at 1-year follow-up. Stent thrombosis was a safety endpoint. RESULTS A total of 413 patients was assessed (145 diabetics and 268 nondiabetics). At 1-year follow-up, the primary endpoint of TLF occurred in 5.1% patients, comprised of 3.9% cardiac deaths, 0.5% TV-MI, and 0.7% CI-TLR. Overall stent thrombosis occurred in 0.5% patients at 1-year follow-up. In the subgroup analysis, TLF occurred in 6.2% diabetics and 4.5% nondiabetics (P =.433) and comprised 4.8% and 3.4% cardiac deaths (P =.447), 0.7% and 0.4% TV-MI (P =.653), and 0.7%, and 0.7% CI-TLR (P =.952) in diabetics and non-diabetics, respectively. Overall stent thrombosis occurred in 0.7% diabetic and 0.4% non-diabetic patient (P =.659). CONCLUSION This registry demonstrates favourable clinical outcomes after the implantation of the ultrathin biodegradable polymer coated Supraflex SES in an all-comers population, with event rates that were similar in diabetic and nondiabetic patients.

Abstract
BACKGROUND Genoss drug-eluting stent (DES) (Genoss Company Limited) is a new ultrathin sirolimus-eluting stent with an abluminal biodegradable polymer and a cobalt-chromium platform. AIMS The aim of this study was to evaluate vascular healing and neointimal coverage after implantation of the Genoss DES using optical coherence tomography (OCT) 6 months postimplantation. METHODS From August 22, 2019 to June 17, 2020, this multicenter, observational, investigator-initiated study enrolled 20 patients who underwent OCT examination 6 months after Genoss DES implantation and provided informed consent. An analyst, blinded to the patients' and procedural information analyzed OCT images at an independent core laboratory. RESULTS Of the 20 patients, 19 with 27 stents in 21 lesions from 21 vessels were included in the analysis, while one patient withdrew consent and was unwilling to undergo follow-up OCT. OCT analysis was performed 204.4 ± 31.9 days after Genoss DES implantation. A total of 4285 stent struts from 661 cross-sections were analyzed. Strut tissue coverage was observed in 98.7 ± 4.3% of struts, with 0.1 ± 1.2% malapposed struts per lesion. The mean thickness of neointimal hyperplasia (NIH) on the covered struts was 0.12 ± 0.04 mm. CONCLUSIONS Six months after stent implantation, most Genoss DES struts were covered with a thin layer of NIH that was evenly distributed along the stent length. This pilot study evaluated the outcomes of 6 months dual antiplatelet therapy in the context of ultrathin strut stents, providing insight into developing ethical standards and a scientific foundation for conducting an adequately designed clinical trial.

Abstract
Background The short-term clinical outcomes of first-generation thicker-strut durable polymer-based drug-eluting stents (DES) have been widely examined. However, there is a scarcity on qualitative research on the long-term usage of DES that evaluated the thinner strut biodegradable stents for coronary artery disease. Hence, we sought to investigate the long-term safety and performance of thinner strut biodegradable polymer-based BioMime sirolimus-eluting coronary stent system in real-world patients with symptomatic ischemic heart disease. Methods This was a retrospective, observational, single-center, post-marketing clinical follow-up study. The primary endpoints were the incidence of major adverse cardiac events (MACE), defined as a composite of cardiac death, myocardial infarction (MI) attributed to target vessel revascularization (TVR), and target lesion revascularization (TLR) at 1-, 2-, 3- and 4-year follow-ups. The secondary endpoints were cardiac death, MI, TLR, TVR, device and procedural success rates, and stent thrombosis (ST). Results In all, 1,188 consecutive patients were enrolled, and 1,333 (1,257 de novo and 76 in-stent restenotic lesions) out of 1,565 lesions were treated with the study device. The mean age of patients was 53.26 ± 10.31 years and 86.2% were male. The quantitative coronary angiographic derived mean lesion length and diameter were 29.62 ± 9.62 mm and 3.01 ± 0.29 mm, respectively. The average length and diameter of the study device implanted were 30.89 ± 6.31 mm and 3.17 ± 0.25 mm, respectively. The cumulative incidence of MACE at 1-, 2-, 3-, and 4 years was 0.61%, 1.47%, 2.08%, and 3.40%, respectively, and cumulative deaths due to cardiac causes were 0.61%, 1.13%, 1.22%, and 1.83%, respectively. There were no cases of TLR or TVR at 1-year follow-up. The cumulative rate of TLR at 2-, 3-, and 4 years was 0.35%, 0.87%, and 1.57%, respectively, while that of TVR was 0.61%, 1.47%, and 2.35%, respectively. Three (0.3%) incidences of probable ST occurred during the 6-month follow-up; no new cases were reported further. In subgroup analysis, MACEs were comparable across the long- and short-length stent groups through 4-year follow-up. Conclusions This long-term study demonstrates the safety and performance of the ultra-thin BioMime sirolimus-eluting stent with satisfactory clinical outcomes in patients with symptomatic ischemic heart disease in real-world scenario.

Abstract
Background Despite significant evolution in stent technology, female gender, and patients with diabetes mellitus, multivessel disease, total occlusions, long lesions, and small vessels represent the "Achilles' heel" of contemporary percutaneous coronary intervention (PCI). We performed a pooled analysis of high-risk subgroup on patient-level data from the T-Flex registry (1,203 patients) and a real-world Indian registry (1,269 patients), with the aim of assessing one-year safety and clinical performance of ultrathin strut biodegradable polymer-coated Supra family of sirolimus-eluting stents (SES) (Sahajanand Medical Technologies Limited, Surat, India) in the real-world, all-comer population. Method We pooled the following high-risk subgroups data from two all-comer registries: female gender (n=678), diabetes mellitus (n=852), multivessel disease (n=406), total occlusions (n=420), long lesions (≥28 mm) (n=1241), and small vessels (≤2.5 mm) (n=726). Both the registries included patients with coronary artery disease who underwent implantation of at least one SES belonging to the Supra family of stents from May 2016 until March 2018, irrespective of lesion complexity and comorbidities. The primary endpoint was the inci-dence of target lesion failure (TLF), a composite of cardiac death, target vessel myocardial infarction, and clinically indicated target lesion revas-cularization by percutaneous or surgical methods up to one year. The safety endpoint was stent thrombosis. Results According to prespecified high-risk subgroups, one-year rates of TLF and overall stent thrombosis, respectively, were as follows: female gender (4.9% and 0.6%), diabetes mellitus (6.9% and 1.0%), multivessel disease (6.4% and 0.8%), total occlusions (5.2% and 0.5%), long lesions (≥28 mm) (6.6% and 0.8%), and small vessels (≤2.5 mm) (6.1% and 1.3%). Conclusion This present pooled analysis demonstrated the one-year safety and clinical performance of ultrathin strut biodegradable polymer-coated Supra family of SES in a real-world, all-comer population, with considerably low rates of TLF and stent thrombosis.

[PMID: 37240923 DOI: 10.3390/jpm13050753] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 04/25/2023] [Accepted: 04/26/2023] [Indexed: 05/28/2023] Open
Abstract
In patients undergoing percutaneous coronary intervention, the second-generation drug-eluting stents (DES) are considered the gold standard of care for revascularization. By reducing neointimal hyperplasia, drug-eluting coronary stents decrease the need for repeat revascularizations compared with conventional coronary stents without an antiproliferative drug coating. It is important to note that early-generation DESs were associated with an increased risk of very late stent thrombosis, most likely due to delayed endothelialization or a delayed hypersensitivity reaction to the polymer. Studies have shown a lower risk of very late stent thrombosis with developing second-generation DESs with biocompatible and biodegradable polymers or without polymers altogether. In addition, research has indicated that thinner struts are associated with a reduced risk of intrastent restenosis and angiographic and clinical results. A DES with ultrathin struts (strut thickness of 70 µm) is more flexible, facilitates better tracking, and is more crossable than a conventional second-generation DES. The question is whether ultrathin eluting drug stents suit all kinds of lesions. Several authors have reported that improved coverage with less thrombus protrusion reduced the risk of distal embolization in patients with ST-elevation myocardial infarction (STEMI). Others have described that an ultrathin stent might recoil due to low radial strength. This could lead to residual stenosis and repeated revascularization of the artery. In CTO patients, the ultrathin stent failed to prove non-inferiority regarding in-segment late lumen loss and showed statistically higher rates of restenosis. Ultrathin-strut DESs with biodegradable polymers have limitations when treating calcified (or ostial) lesions and CTOs. However, they also possess certain advantages regarding deliverability (tight stenosis, tortuous lesions, high angulation, etc.), ease of use in bifurcation lesions, better endothelialization and vascular healing, and reducing stent thrombosis risk. In light of this, ultrathin-strut stents present a promising alternative to existing DESs of the second and third generation. The aims of the study are to compare ultrathin eluting stents with second- and third-generation conventional stents regarding procedural performance and outcomes based on different lesion types and specific populations.

Abstract
Background Drug-eluting coronary stents with ultrathin struts and biodegradable polymers have been shown to reduce inflammation, neointimal proliferation, and thrombus formation, leading to less early and late complications in patients with coronary artery disease as compared to thinner strut and durable polymer second-generation stents. In Oman, currently, second-generation stents are used for all patients. Objective The purpose of this feasibility study was to evaluate the clinical safety and performance of ultrathin-strut (60 μm) biodegradable polymer-coated sirolimus-eluting stents in an all-comers patient population. Methods This was a prospective, observational, single-center, and single-arm investigator-initiated study from August 2018 to August 2019. Inclusion criteria: 18 years of age, patients with symptomatic coronary artery disease indicated for percutaneous coronary intervention, and stenting of at least one coronary lesion. All patients were followed clinically or telephonically at 12 months after the index procedure. Results A total of 88 patients were recruited in the study, but 10 patients were lost to follow-up and hence excluded from the analysis. The overall mean age was 63 ± 13 years and 78% were males. The main comorbid conditions were hypertension (58%), diabetes mellitus (49%), and hyperlipidemia (26%). Fifty-three percent presented with unstable angina or non-ST elevation myocardial infarction (MI), 10% with ST elevation MI, recent MI 16%, 18% with stable angina, and 1.3% in cardiogenic shock. The mean left ventricular ejection fraction of the cohort was 46 ± 14%. Angiographically, Type A lesions were seen in 25%, Type B in 32%, and Type C in 42%. Left anterior descending stenting was done in 44%, right coronary artery in 32%, left circumflex artery in 14%, left main in 5%, and graft stenting in 4%. Device success was 96%. Procedural success was seen in 97% of patients. At 1-year follow-up, 93% were asymptomatic; overall device-oriented clinical events were 6.8% including cardiac death in 2.7%, target-vessel MI in 2.7%, and target-lesion revascularization in 1.3% which all occurred in uncontrolled diabetic patients. Conclusions At index admission and 1 year, ultrathin-strut biodegradable polymer-coated sirolimus-eluting stent study showed low device-related adverse clinical events which are comparable to published data for the second-generation stents. This feasibility study shows that these stents can be used in all types of stent-indicated patients with added advantages of biodegradable polymer and ultrathin struts. In addition, measures to prevent, diagnose, and control diabetes need to be taken in Oman as this cohort of patients develop ST after stenting.

Abstract
PURPOSE Although the field of interventional cardiology has witnessed extraordinary progression, the search of an ideal coronary drug-eluting stent is still going on. Tetriflex (Sahajanand Medical Technologies Limited, Surat, India) is a latest generation biodegradable polymer-coated ultrathin (60 µm) sirolimus-eluting stent (SES) with unique Long Dual Z-link (LDZ) design. The present registry reports the 12 months clinical follow-up results of Tetriflex SES in unselected, real-world patients with coronary artery disease (CAD). METHODS This was an investigator-initiated, retrospective, multi-center, single-arm, observational registry conducted in India between March-2017 and March-2018. The registry included 1269 consecutive patients with CAD who underwent implantation of at least one Tetriflex SES. The primary outcome was considered as target lesion failure (TLF), which was a composite of cardiac death, target-vessel myocardial infarction (TV-MI) and clinically-driven target lesion revascularisation (CD-TLR) at 12 months follow-up. The safety outcome, at 12 months follow-up, was stent thrombosis. RESULTS Mean age of patients was 54.99±10.80 years. Among all, 36.6% patients had diabetes and 51.7% patients had multi-vessel disease. A total of 1515 lesions were treated with 1682 Tetriflex SES of which 73.2% lesions were complex B2/C type and 14.7% were totally occluded. At 12 months, the cumulative incidence of TLF was 5.75% comprising 0.8% cardiac death, 3.20% TV-MI and 1.72% CD-TLR. All the incidences of definite/probable stent thrombosis (n = 4, 0.32%) were reported within 30 days of the index procedure. Twelve-month cumulative incidence of TLF in diabetic subgroup was 7.10%. CONCLUSION Twelve months clinical follow-up results of an ultrathin (60 µm), biodegradable polymer-coated Tetriflex SES, with unique LDZ-link, further clarify its safety and effectiveness in real-world, unselected Indian patients.

Abstract
New-generation drug-eluting stents (DESs) represent the standard of care for patients undergoing percutaneous coronary intervention (PCI). Recent iterations in DES technology have led to the development of newer stent platforms with a further reduction in strut thickness. This new DES class, known as ultrathin struts DESs, has struts thinner than 70 µm. The evidence base for these devices consists of observational data, large-scale meta-analyses, and randomized trials with long-term follow-up, which have been conducted to investigate the difference between ultrathin struts DESs and conventional new-generation DESs in a variety of clinical settings and lesion subsets. Ultrathin struts DESs may further improve the efficacy and safety profile of PCI by reducing the risk of target-lesion and target-vessel failures in comparison to new-generation DESs. In this article, we reviewed device characteristics and clinical data of the Orsiro (Biotronik, Bülach, Switzerland), Coroflex ISAR (B. Braun Melsungen, Germany), BioMime (Meril Life Sciences Pvt. Ltd., Gujarat, India), MiStent (MiCell Technologies, USA), and Supraflex (Sahajanand Medical Technologies, Surat, India) sirolimus-eluting stents.

Abstract
Second-generation drug-eluting stents (DES) are considered standard of care for revascularization of patients undergoing percutaneous coronary intervention. Besides the polymer and antiproliferative drug used, the metallic backbone of DES is an attractive target for further development. Ultrathin-strut DES (≤70 μm strut thickness) are more flexible, have an improved trackability and crossability compared to conventional second-generation DES. Importantly, ultrathin-strut DES reduce the risk of in-stent restenosis, thereby decreasing the risk of angiographic and clinical restenosis. In this narrative review, we will discuss the clinical outcomes of the commercially available ultrathin-strut DES.

Abstract
OBJECTIVE T-Flex registry was designed to investigate the safety and clinical performance of the ultrathin (60 µm) strut biodegradable polymer-coated sirolimus-eluting stent (SES) with a unique long dual Z (LDZ) link design on a cobalt-chromium stent platform (Sahajanand Medical Technologies Pvt. Ltd., Surat, India) in a real-world all-comer population including high-risk subgroups. METHODS This was an observational, multicenter, single-arm, and investigator-initiated retrospective registry. A total of 1,203 patients treated with an ultrathin biodegradable polymer-coated SES, irrespective of lesion complexity, comorbidities, and acute presentation were analyzed from May 2016 to January 2017. The primary endpoint was the one-year incidence of target lesion failure (TLF), a composite of cardiac death, target-vessel myocardial infarction (TV-MI), and clinically-indicated target lesion revascularization (CI-TLR). Stent thrombosis was assessed as an additional safety endpoint. RESULTS At the one-year follow-up, TLF was observed in 3.8% [95% confidence interval (CI) 2.9-5.1] patients, composed of 0.6% (95% CI: 0.3-1.3) cardiac death, 1.3% (95% CI: 0.8-2.2) TV-MI, and 1.9% (95% CI: 1.3-2.9) CI-TLR. In the high-risk subgroups, TLF at one-year was 6.8% (95% CI: 4.6-9.8) in patients with diabetes, 5.2% (95% CI: 3.4-8) in patients with small-vessel disease, 6.1% (95% CI: 3.9-9.6) in patients with ST-elevation myocardial infarction, and 4.5% (95% CI: 2.4-8.3) in patients with total occlusion. During follow-up, stent thrombosis was reported in 0.8% (95% CI: 0.4-1.5) patients in the overall population. CONCLUSION Low event rates of TLF and stent thrombosis at one-year follow-up indicate that this ultrathin biodegradable polymer-coated SES has encouraging safety and clinical performance in real-world all-comer populations as well as in high-risk subgroups.

Abstract
BACKGROUND Evermine 50™ (Meril Life Sciences Pvt. Ltd., India) everolimus-eluting stent system (EES) is a novel ultrathin strut (50 µm) cobalt-chromium coronary drug-eluting stent (DES) platform with biodegradable polymer coating. The Evermine 50 EES-KLES study aimed to evaluate the Evermine 50 EES in terms of 24-month clinical safety and performance in patients with coronary artery disease (CAD). METHODS This retrospective study consisted of 171 patients (258 lesions) implanted with Evermine 50 EES for managing CAD. We analyzed the major adverse cardiac events (MACE) incidence, defined as a composite of cardiac death, myocardial infarction, and ischemia-driven target lesion revascularization (ID-TLR) at 6-, 12-, and 24-month follow-up. RESULTS A total of 171 patients were included with a mean age of 57.85 ± 10.05 years, of which, 139 (81.29%) were men, 69 (40.35%) were hypertensive, and 70 (40.94%) were diabetic. The incidence of MACE was 1 (0.58%), 3 (1.81%), and 4 (2.42%) at 6-, 12-, and 24-month follow-up, respectively. There were three cases (1.82%) of cardiac death and one case (0.61%) of ID-TLR up to 24 months. None of the patients was presented with definite or probable stent thrombosis (ST). CONCLUSION This study demonstrated that implantation of ultrathin strut Evermine 50 EES resulted in a low rate of incidence of MACE, indicating a favourable clinical safety and performance profile of Evermine 50 EES in patients with CAD [Clinical Trials Registry-India (CTRI) Number: CTRI/2017/09/009939)].

Abstract
Percutaneous coronary interventions with drug-eluting stents is currently the preferred revascularization treatment strategy for coronary artery disease. Following the first generation, the second-generation drug-eluting stents was designed with a thinner strut, better biocompatible polymer with/without bioresorbable coating or even polymer-free struts. The SUPRAFLEX stent system has ultra-thin struts (60 μm) across all stent diameters and a biodegradable polymer coating, enabling 70% of the sirolimus elution within 7 days. SUPRAFLEX has been assessed in large scale randomized controlled trials. This review summarizes the design of the SUPRAFLEX stent, the results of the pivotal clinical trials and outlines the ongoing research programs.

Abstract
BACKGROUND The FLEX-LONG study assessed the safety and clinical outcomes of ultra-long (44 mm/48 mm) biodegradable polymer-coated Supraflex (Sahajanand Medical Technology Pvt. Ltd., Surat, India) sirolimus-eluting stents (SES) in real-world patients with complex, long coronary artery lesions. METHODS It was an investigator-initiated, retrospective, non-randomized, observational and single-center study, which evaluated one-year results of 141 patients who had undergone implantation of at least one ultra-long (44 mm/48 mm) Supraflex SES. The incidence of major adverse cardiac events (MACE), a composite of cardiac death, myocardial infarction (MI) and target lesion revascularization (TLR), at one-year follow-up was considered as primary outcome. Stent thrombosis was analyzed as a safety outcome. RESULTS The mean age of the study population was 56.2±9.6 years and 78.0% (110/141) patients were male. The study analyzed high risk patients, including 62 (44.0%) hypertensive and 60 (42.6%) diabetic patients. Total 147 target lesions were treated, including 25 (17.0%) total occlusions. Total 51 (34.7%) and 96 (65.3%) Supraflex SES of 44 mm and 48 mm were implanted, respectively. Average stent length and diameter were 46.6±1.9 mm and 3.4±0.2 mm, respectively. One-year follow-up was obtained in 100% of patients. There was one probable stent thrombosis after three weeks. At one-year follow-up, 99.3% of patients remained event free. CONCLUSIONS The results of the FLEX-LONG study support the use of ultra-long (44 mm/48 mm) Supraflex SES, in the treatment of high-risk real-world patients. The stent appeared to be safe and effective at one-year with low clinical events in complex, long coronary artery lesions.

Abstract
Aim The TAXCO study was designed to compare the degree of neointimal coverage and the prevalence of malapposition at 6 months subsequent to implantation of ultrathin biodegradable polymer‐coated sirolimus‐eluting stents (SES) and durable polymer‐coated everolimus‐eluting stents (EES) of thin strut thickness using optical coherence tomography (OCT). Methods The TAXCO study included a total of 42 patients who gave consent and underwent OCT examination between August 2017 and September 2017. Of 42, five patients' OCT examinations were of insufficient quality for quantitative analysis. Thus, the OCT analysis group consisted of 37 patients. Among them, 16 patients were treated with Xience (Abbott Vascular) and 21 with Tetriflex (Sahajanand Medical Technologies Pvt. Ltd., Surat, India), 6 (±1) months earlier at our institution. The OCT was performed using a C7 Dragonfly™ imaging catheter (St. Jude Medical Inc.). All OCT images were analyzed at an independent core laboratory (Cardiovascular Research Center, São Paulo, Brazil) by analysts who were blinded to patient and procedural information. Results A total of 763 crosssections (6,882 struts) were analyzed in Xience group, and 1,127 crosssections (9,968 struts) in Tetriflex group. At 6 months, on per‐lesion basis, no significant differences were observed between Xience group and Tetriflex group in mean percentage of uncovered struts (1.87 ± 3.86 vs. 2.42 ± 3.46, p = .137) and malapposed struts (0.05 ± 0.2 vs. 0.21 ± 0.69, p = .302). Strut‐level neointimal thickness also did not differ between Xience group and Tetriflex group (0.18 ± 0.12 vs. 0.14 ± 0.08 mm, p = .286). Conclusion This OCT study found no significant difference in strut coverage and neointimal thickness at 6 months after implantation of biodegradable polymer‐coated Tetriflex, when compared with durable polymer‐coated Xience.

Abstract
BACKGROUND Although a number of drug-eluting stents have been developed with different design, composition, and polymers, the search for an ideal drug-eluting stent is ongoing. The Tetriflex (Sahajanand Medical Technology, Surat, India) is a newer-generation, ultrathin (60 µm) biodegradable polymer-coated sirolimus-eluting stent (SES) designed with a unique long dual Z-link on a cobalt-chromium alloy. The present registry aimed to evaluate the safety and clinical outcomes of the Tetriflex SES at 6-month post-implantation. METHODS This was an investigator-initiated, retrospective, multicenter, single-arm, observational registry conducted at five tertiary-care centers in India. A total of 1,269 consecutive patients with coronary artery disease who underwent implantation of at least one Tetriflex SES between March 2017 and March 2018 were included. The primary outcome was considered a composite of cardiac death, myocardial infarction and target-lesion revascularization (TLR) at 6-month follow-up. Stent thrombosis was evaluated as a safety outcome at 6-month follow-up. RESULTS The mean age of patients was 54.99±10.80 years. Among 1,515 lesions treated with 1,682 Tetriflex SES, 58.3% were type C lesions. Six-month follow-up was done for 1,245 of 1,269 (98.1%) patients. At 6 months, composite events had occurred in 31 (2.5%) patients, consisting of ten (0.8%) cardiac deaths, 16 (1.3%) myocardial infarctions, and five (0.4%) TLRs. Stent thrombosis was observed in seven (0.56%) cases at 6 months. A subgroup analysis between diabetic and nondiabetic patients did not reveal any statistically significant difference for clinical outcomes at 6-month follow-up. CONCLUSION The results of the current registry outline the safety and effectiveness of the Tetriflex SES in real-world patients, as it displayed favorable clinical outcomes at 6-month follow-up, with low incidence of TLR and stent thrombosis.

Abstract
OBJECTIVE To prospectively evaluate safety and efficacy of the ultrathin strut biodegradable polymer-coated Supraflex sirolimus-eluting stent (S-SES) in 'real world' patient population requiring percutaneous coronary intervention (PCI). METHODS National, prospective, multicentre, single-arm, all-comers, observational registry of 469 patients treated with S-SES from July 2015 and November 2016 in 11 centres in UK. Primary endpoint was target lesion failure (TLF) at 12 months (cardiac death, target vessel myocardial infarction (MI) or clinically driven target lesion revascularisation (TLR)). Secondary endpoints included safety and performance outcomes at 12 months-overall stent thrombosis (ST), all-cause mortality, any MI, target vessel failure (TVF) and major adverse cardiac events (MACE-composite of cardiac death, MI, emergent or repeat revascularisation). RESULTS At 12 months, the primary endpoint occurred in 11 (2.4%) of 466 patients, consisting of 4 (0.9%) cardiac deaths, 3 (0.6%) target vessel MI and 7 (1.5%) TLR. Secondary endpoints findings included all-cause mortality in 6 (1.3%), TVF of 14 (3%), no definite ST, 1 (0.2%) probable ST and 3 (0.6%) possible ST. Overall MACE was observed in 18 (3.9%). CONCLUSIONS The S-FLEX UK registry showed that the S-SES is safe with a low incidence of TLF in routine clinical practise in patients with coronary artery disease being treated by PCI.

Abstract
Cardiovascular disease is one of the most important causes of morbidity and mortality in the world. Treatment in most patients is percutanseous coronary intervention. One of new generation drug-eluting stent (DES) is Sirolimus Eluting Stent. The current study was aimed to investigate the clinical outcomes and complications of treatment with supraflex stent during one year follow up in patients with coronary artery disease. This cross-sectional study was performed on patients with myocardial ischemia who were candidate for coronary angioplasty between 2017-2018 in Imam Reza Hospital, Mashhad, Iran.. Patients were followed for four primary end points including Target lesion revascularization (TLR), stent thrombosis (ST), myocardial infarction (MI) and cardiac death (CD) for one year. Descriptive data were analyzed by Freidman at a significance level of 0.05. A total of 287 patients were enrolled in the study. There was no TLR, MI, ST and CD records in the one month follow up. Six months follow up demonstrated three TLR patients and three MI patients, but no ST and death were reported. After one year follow up, three cases of CD and four ST cases were found in patients treated with supraflex stent. Based on the Freidman test, the highest rate of TLR was revealed in a six-month follow-up when comparing with one-month and twelve-month follow-up (p = 0.05). No significant relationship was found between the other cases. The most common complications associated with supraflex stent were TLR and MI in six-month follow-up. The most likely occurrence of CD and ST were found in one year follow up.

Abstract
BACKGROUND Supraflex is a sirolimus-eluting stent with a biodegradable polymer coating and ultra-thin struts. We aimed to compare Supraflex with the standard of care, Xience, an everolimus-eluting stent with a durable polymer coating, regarding clinical outcomes with a randomised trial in an all-comer population. METHODS We did a prospective, randomised, single-blind, multicentre study (TALENT) across 23 centres in Europe (the Netherlands, Poland, the UK, Spain, Bulgaria, Hungary, and Italy). Eligible participants were aged 18 years or older, had one or more coronary artery stenosis of 50% or greater in a native coronary artery, saphenous venous graft, or arterial bypass conduit, and had a reference vessel diameter of 2·25-4·50 mm. Patients underwent percutaneous coronary intervention in an all-comer manner. We randomly assigned patients (1:1) to implantation of either a sirolimus-eluting stent with a biodegradable polymer coating and ultra-thin struts (Supraflex) or an everolimus-eluting stent with a durable polymer coating (Xience). Randomisation was done by local investigators by use of a web-based software with random blocks according to centre. The primary endpoint was a non-inferiority comparison of a device-oriented composite endpoint-cardiac death, target-vessel myocardial infarction, or clinically indicated target lesion revascularisation-between groups at 12 months after the procedure, assessed in an intention-to-treat population. On assumption of 1-year composite endpoint prevalence of 8·3%, a margin of 4·0% was defined for non-inferiority of the Supraflex group compared with the Xience group. This trial is registered with ClinicalTrials.gov, number NCT02870140. FINDINGS Between Oct 21, 2016, and July 3, 2017, 1435 patients with 1046 lesions were randomly assigned to Supraflex, of whom 720 received the index procedure, and 715 patients with 1030 lesions were assigned to Xience, all receiving the index procedure. At 12 months, the primary endpoint had occurred in 35 patients (4·9 %) in the Supraflex group and in 37 patients (5·3%) in the Xience group (absolute difference -0·3% [one-sided 95% upper confidence bound 1·6%], pnon-inferiority<0·0001). Definite or probable stent thrombosis prevalence, a safety indicator, was low in both groups and did not differ between them. INTERPRETATION The Supraflex stent was non-inferior to the Xience stent for a device-oriented composite clinical endpoint at 12 months in an all-comer population. Supraflex seems a safe and effective alternative drug-eluting stent to other stents in clinical practice. FUNDING European Cardiovascular Research Institute.
