Abstract
INTRODUCTION This pooled analysis was conducted to assess the clinical safety and performance of the Supra family (Sahajanand Medical Technologies Ltd., Surat, India) of sirolimus-eluting stents (SES) in patients with acute coronary syndromes (ACSs) including ST-segment elevation myocardial infarction (STEMI) from two real-world all-comers Indian registries at 1 year. METHODS We evaluated 1,824 patients with ACS who underwent percutaneous coronary intervention with the Supra family of SES from two real-world Indian registries (891 patients from T-Flex registry and 933 patients from Tetriflex real-world registry). The primary endpoint was the incidence of target lesion failure (TLF) defined as a composite of cardiac death, target-vessel myocardial infarction (TV-MI), and target lesion revascularization (TLR) at 1-year follow-up. The safety endpoint was stent thrombosis at 1-year follow-up. RESULTS Among a total of 1,824 patients with ACS, 689 (37.8%) patients presented with STEMI. In ACS and STEMI groups, 47.6% and 41.8% patients had multivessel disease, respectively. Of 2,128 lesions in ACS group, 76.7% lesions were type B2/C and 16.2% lesions were totally occluded. In the STEMI group, out of 784 treated lesions, 76.7% were type B2/C lesions and 21.9% were totally occluded. At 1-year follow-up, incidence of TLF was 5.3% (cardiac death: 0.9%, TV-MI: 2.5%, TLR: 1.9%) in patients with ACS and 6.2% (cardiac death: 1.4%, TV-MI: 2.1%, TLR: 2.7%) in patients with STEMI. The 1-year rate of definite/probable stent thrombosis was 0.3% and 0.7% in patients with ACS and STEMI, respectively. CONCLUSION This patient-level pooled analysis provides evidence for the safe and effective use of the Supra family of SES in complex patient populations such as ACS and even in STEMI with favorable rates of TLF and stent thrombosis at 1-year follow-up.

Abstract
BACKGROUND There is little information on the performance of the new generation of stents with bioabsorbable polymers in the Latin American population. This registry aimed to further validate the safety and efficacy of the Orsiro bioresorbable-polymer sirolimus-eluting stent (BPSES) in unselected patients undergoing percutaneous coronary intervention (PCI) in Chilean centers. METHODS We prospectively enrolled patients undergoing PCI with BPSES in 6 Chilean centers. The primary endpoint was defined as the composite of cardiac death, target vessel-related myocardial infarction (MI), and clinically driven target lesion revascularization at 1-year follow-up. RESULTS From April 2017 to February 2019, 520 patients were enrolled in the registry, more frequently male (74.6%), with a mean age of 62.7 ± 10.8 years and a high prevalence of diabetes (40.2%). The clinical presentation was stable angina in 41.1% (n = 214), acute MI in 52.5% (n = 167 [32.1%] ST-elevation MI and n = 106 [20.4%] non-ST-elevation MI), and unstable angina in 6.3% (n = 33). Of 610 treated lesions, 425 (69.7%) were American College of Cardiology/American Heart Association type B or C lesions. Device and procedural success were achieved in 99.4% and 98.7% of the patients, respectively. The primary endpoint of the study occurred in 4%, primarily driven by cardiac death. CONCLUSIONS The results of the ROSES multicenter registry indicated good clinical outcomes of BPSES Orsiro in all-comers Latin Americann patients undergoing PCI, despite the high-risk patients and treated lesions.

Gender-Associated Outcomes Following Percutaneous Coronary Intervention With a Third-Generation, Ultrathin-Strut Drug-Eluting Stent: A Real-World, Single-Center Experience. Front Cardiovasc Med 2022; 8:796604. [PMID: 35224025 PMCID: PMC8873376 DOI: 10.3389/fcvm.2021.796604] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Accepted: 12/30/2021] [Indexed: 11/13/2022] Open
Abstract
Introduction In recent years, the new third-generation ultrathin bioresorbable-polymer sirolimus-eluting stent (BP-SES), characterized by some of the thinnest struts among commercially available devices (60–80 μm) and an amorphous silicon carbide coating, has been introduced for the treatment of coronary artery disease (CAD). The present study aimed to assess different clinical outcomes and safety of this drug-eluting stent in male and female patients in a real-world setting. Methods The present study is a retrospective analysis including all patients treated with BP-SES between January 2017 and December 2019 at a single high-volume center. Follow-up data, including stress test results and clinical setting, were collected during outpatient visits or by telephone contact. Patients symptomatic for angina or with a positive stress test were addressed to CT scan/coronary angiogram. The main study outcome was target lesion failure (TLF), defined as a composite of cardiovascular death, target vessel myocardial infarction, or target lesion revascularization. Results Overall, 66 (15.9%) female and 349 (84.1%) male patients were included; women were older (median age 70 vs. 66, P = 0.003) and with a lower body mass index (BMI) (25.0 vs. 26.1, P = 0.010) compared to men, with no other relevant differences in baseline characteristics. Indication for percutaneous coronary intervention (PCI) was acute coronary syndrome in 86 (20.7%) of the cases, with no significant differences between male and female patients. A total of 558 lesions were treated with BP-SES stents, 90 in women and 468 in men (1.36 vs. 1.34 lesions per patient, P = 0.83); cumulative stent length (33.6 vs. 38.4 mm, P = 0.078), and mean stent diameter (2.92 vs. 3.0 mm, P = 0.39) did not differ in women compared to men. Technical and clinical successes were achieved in all patients. Stent thrombosis (ST) occurred in 2 (0.5%) patients, both men. TLF occurred in 10 (2.9%) men and 2 (3.0%) women after a median follow-up of 402 days, without significant differences at log-rank analysis (2.34 events per 100 patient-years in men, 2.53 in women; P = 0.80). Conclusion Ultrathin struts BP-SES showed to be a safe and effective option for the treatment of CAD in both women and men, with a very low ST rate and favorable long-term outcomes.

Catheter Cardiovasc Interv 2021; 98:848-856. [PMID: 32890442 PMCID: PMC9292184 DOI: 10.1002/ccd.29254] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Revised: 06/11/2020] [Accepted: 08/08/2020] [Indexed: 11/07/2022]
Abstract
OBJECTIVES This analysis of pooled individual patient data (IPD) aimed to evaluate the safety and efficacy of a bioresorbable polymer sirolimus eluting stent system (BP-SES; Orsiro) compared to a durable polymer everolimus eluting stent system (DP-EES; Xience) in the pooled population as well as in subgroups. METHODS IPD with up to 12 months follow-up of the randomized controlled trials BIOFLOW-II (NCT01356888), -IV (NCT01939249), and -V (NCT02389946) as well as the all comers registry BIOFLOW-III (NCT01553526) were pooled. A total of 3,717 subjects (2,923 in BP-SES and 794 in DP-EES) with 5,328 lesions (4,225 lesions in BP-SES and 1,103 in DP-EES) were included in the IPD. The primary endpoint was target lesion failure (TLF) at 12 months follow-up. Subgroups analyzed included diabetes, age (≥65 years), gender, complex lesions (B2/C), small vessels (reference vessel diameter ≤2.75 mm), multivessel treatment, renal disease, and patients with acute coronary syndrome. RESULTS Overall, TLF at 12 months was significantly lower with 5.2%in the BP-SES group versus 7.6% in the DP-EES group (p = .0098). Similarly, target vessel myocardial infarction (TV-MI) was 3.1 versus 5.7% (p = .0005). The rate of stent thrombosis was similar in both groups (0.004%). By regression analysis, an independent stent effect in favor of BP-SES was observed for TLF (p = .0043) and TV-MI (p = .0364) in small vessels. CONCLUSION Results of this IPD analysis suggest that the BP-SES with ultrathin struts is as safe as and more efficacious than DP-EES in the overall cohort and especially in small vessels.

Abstract
Background Despite numerous studies supporting the outperformance of ultrathin-strut bioresorbable polymer sirolimus-eluting stent (Orsiro SES, Biotronik AG), the generalizability of the study results remains unclear in the Asian population. We sought to evaluate the clinical outcomes of the Orsiro SES in unselected Thai population. Methods The Thailand Orsiro registry was a prospective, open-label clinical study evaluating all patients with obstructive coronary artery disease implanted with Orsiro SES. The primary endpoint was target lesion failure (TLF) at 12 months. TLF is defined as a composite of cardiac death, target vessel myocardial infarction (TVMI), emergent coronary artery bypass graft (CABG), and clinically driven target lesion revascularization (CD-TLR). Patients with diabetes, small vessels (≤ 2.75 mm), chronic total occlusions (CTOs), and acute myocardial infarction (AMI) were pre-specified subgroups for statistical analysis. Result A total of 150 patients with 235 lesions were included in the analysis. Half of the patients (53.3%) presented with AMI, and 24% had diabetes. Among 235 lesions, 93(39.4%) were small vessels, and 24(10.2%) were chronic total occlusions. The primary endpoint, TLF at 12 months, occurred in eight patients (5.3%), predominately caused by cardiac death. By contrast, the incidences of TVMI and CD-TLR were null. The outcomes in pre-specified subgroup were not different from the overall population (all p > 0.05). One definite late stent thrombosis(0.7%) was incidentally observed during primary percutaneous coronary intervention to the non-target vessel. Conclusion The safety and efficacy of the ultrathin strut sirolimus-eluting stent in unselected cases are confirmed in the Thailand Orsiro registry. Despite the high proportion of pre-specified high-risk subgroups, the excellent stent performance was consistent with the overall population. Trial Registration TCTR20190325001.

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.

Adaptive coronary artery rotational motion through uncaging of a drug-eluting bioadaptor aiming to reduce stress on the coronary artery. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2021; 39:52-57. [PMID: 34629284 DOI: 10.1016/j.carrev.2021.09.009] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 09/23/2021] [Accepted: 09/27/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Caged drug-eluting stents impede natural coronary rotational motion and increase vessel stress, which can contribute towards adverse events. The DynamX™ Drug-Eluting Bioadaptor is a cobalt‑chromium platform with a novel mechanism that uncages the vessel after the bioresorbable coating resorbs over six months. This study aimed to analyze the effects of the rotational uncaging in a finite element analysis (FEA) model, validating its effect on coronary artery rotational motion through in-vivo stationary intravascular ultrasound (IVUS). METHODS Maximum Von Mises stresses were measured in an FEA model and compared for caged and uncaged bioadaptors. Stationary IVUS images from 20 patients enrolled in a single center were acquired post implantation and at 9-12-month follow-up to evaluate coronary artery rotational motion. RESULTS The FEA model showed that rotational uncaging of the bioadaptor reduces peak stress by 70%. In-vivo, the in-bioadaptor segment was significantly distorted post-implant compared to the native distal and proximal vessel, measured by IVUS: The sum of clockwise and counterclockwise rotational motion (net-effect rotational motion) was -2.7 ± 4.3° versus 0.5 ± 5.0° (proximal vessel), p = 0.036, and versus 0.2 ± 3.8° (distal vessel), p = 0.042. At follow up, when the bioadaptor had uncaged, the vessel returned towards its equilibrium (net-effect rotational motion -0.2 ± 5.6°), with no significant difference between the vessel segments. CONCLUSIONS In concurrence with the FEA observation, the in-vivo IVUS-analysis demonstrates that uncaging of the bioadaptor affects coronary artery rotational motion. The effect of these findings on reducing clinical events warrants further investigation.

Abstract
AIMS The aim of this study was to assess the real-world clinical performance of a sirolimus-eluting ultrathin-strut drug-eluting stent (DES) (Orsiro) in a large nationwide cohort of patients undergoing percutaneous coronary intervention (PCI). METHODS AND RESULTS From the Swedish Coronary Angiography and Angioplasty Registry, the two-year outcomes of 4,561 patients implanted with Orsiro (Orsiro group) and 69,570 receiving other newer-generation DES (n-DES group) were analysed. The rate of definite stent thrombosis was low in both groups (0.67% and 0.83% for Orsiro and n-DES, respectively; adjusted hazard ratio [HR] 0.90, 95% confidence interval [CI]: 0.55-1.46, p-value 0.66). Restenosis was also infrequent (1.5% vs 2.0% with Orsiro and n-DES, adjusted HR 0.81, 95% CI: 0.63-1.03, p-value=0.09). The risk of target lesion revascularisation by PCI was lower in the Orsiro group (1.6% vs 2.3%, adjusted HR 0.75, 95% CI: 0.60-0.94, p-value=0.013). All-cause mortality and myocardial infarction did not show a statistically significant difference between the two groups (mortality of 7.5% in both groups, adjusted HR 0.99, 95% CI: 0.72-1.35, p-value=0.94; 6.0% vs 5.2% for myocardial infarction, adjusted HR 1.19, 95% CI: 1.00-1.43, p-value=0.06). CONCLUSIONS In a nationwide scenario, the use of a sirolimus-eluting ultrathin-strut DES portended favourable clinical outcomes.

Abstract
Objective: Supraflex (Sahajanand Medical Technologies Pvt. Ltd, Surat, India) is the latest generation of biodegradable polymer-coated sirolimus-eluting coronary stent designed on ultra-thin (60 µm) cobalt–chromium platform with flexible “S-link.” The present study was designed to establish the safety and clinical performance of Supraflex in real-world Indian patients with coronary artery disease. Methods: The study included 839 consecutive patients with coronary artery disease who were implanted with Supraflex from January 2014 to August 2017 at six different tertiary care centers in India. Follow-up was performed at 30 days, 6 months, and 12 months after the index procedure. The primary end-point of the study was the incidence of major adverse cardiac events (MACE), a composite of cardiac death, myocardial infarction (MI), and target lesion revascularization (TLR) at the 12-month follow-up. The occurrence of stent thrombosis was analyzed as safety end-point. Results: A total of 1025 lesions were treated by implantation of 1098 Supraflex stents. At the 12-month follow-up, MACE was 4.92%, including 7 (0.86%) cardiac deaths, 16 (1.97%) MI, and 17 (2.09%) TLR. Only three incidences of stent thrombosis were found at the 12-month follow-up. Conclusion: The study results showed excellent safety and clinical effectiveness of Supraflex in a high proportion of high-risk real-world Indian patients with coronary artery disease.

Ultrathin Biodegradable-Polymer Orsiro Drug-Eluting Stent Performance in Real Practice Challenging Settings. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2020; 30:12-17. [PMID: 33012686 DOI: 10.1016/j.carrev.2020.09.027] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 09/15/2020] [Accepted: 09/21/2020] [Indexed: 11/21/2022]
Abstract
BACKGROUND The Orsiro cobalt-chromium stent platform (Biotronik, Bülach, Switzerland) is one of the first devices in the era of ultrathin struts. However, data regarding the efficacy of Orsiro stent in patients with challenging anatomical conditions obtained from daily clinical practice are scant. METHODS We retrospectively reviewed the long-term outcomes, defined as target lesion revascularization (TLR), target vessel revascularization (TVR), stent thrombosis (ST) and cardiovascular (CV) mortality over a six years period, in 1161 consecutive patients (mean age 64.3 ± 11.2 years old, 681 males) treated with 2327 Orsiro stents in our institution who presented with challenging anatomic/angiographic features. RESULTS The mean number of implanted stents was 1.7 ± 2.1 whereas the mean stent diameter and length were 3.6 ± 1.1 and 32.7 ± 15.6 mm, respectively. Mean follow-up duration was 35.6 ± 17 months (range 1-77 months); 923 patients (79.5%) reached the 3-year follow-up. The global rates of TLR, TVR, ST and CV mortality were 0.1%, 1.37%, 0.002%, and 1.9%, respectively with scarce statistically significant differences in multivessel disease, severe calcification, and lesion length > 41 mm. Multivariate regression analysis revealed that age, stent dislodgement, early stent thrombosis (p = 0.001) and lesion length ≥ 41 mm (p = 0.001) were independent predictors of TVR. Similarly, the occurrence of TLR was independently predicted by age, severe calcification, use of IVUS and Rotablator (p = 0.002), early stent thrombosis, LM bifurcation and length ≥ 41 mm (p = 0.001). CONCLUSIONS The Orsiro stent confirmed a very high efficacy profile in all anatomical scenarios with very low rates of clinically driven TLR and TVR, CV mortality and ST at 3-years.

Abstract
BACKGROUND The BIOFLOW-III Canada registry aimed to evaluate the safety and efficacy of Orsiro sirolimus-eluting stents (SES) with biodegradable polymer, in an all-comers patient population. METHODS We conducted a prospective, non-randomized, multi-center, observational all-comers registry of patients undergoing percutaneous coronary intervention (PCI) with Orsiro SES at two high-volume Canadian centers. The primary endpoint was one-year target lesion failure (TLF) defined as a composite of cardiac death, target-vessel myocardial infarction (MI), coronary artery bypass grafting and clinically driven target lesion revascularization. Four subgroups were pre-defined: i) diabetic patients; ii) small vessels (≤2.75 mm); iii) chronic total occlusions (CTO) and iv) acute MI. RESULTS From May 2014 to July 2016, 250 patients (mean age 66.2 ± 10.8 years, 75.6% males, 30% diabetes) underwent PCI with Orsiro SES for 385 coronary lesions. The mean stent diameter was 2.98 ± 0.50 mm and the mean stent length was 22 ± 8 mm. Clinical device and procedural success rates were with 99.5% and 97.6%, respectively. The overall one-year TLF rate was 2.8% [95% confidence interval (CI) 1.4-5.8%], whereas TLF rates were 4.1% [95%CI 1.3-12.2%], 3.2% [95%CI 1.2-8.4%], 8.3% [95%CI 2.2-29.4%], and 2.6% [95%CI 0.7-9.9%] in patients with diabetes, small vessels, CTO, and acute MI, respectively. One case of possible stent thrombosis (ST) was reported (0.4% [95%CI 0.1-2.8%]), while no cases of definite/probable ST was observed at one year. CONCLUSION Our data provide further evidence of the safety and clinical performance of Orsiro SES in an unselected, real-world, complex patient population. CONDENSED ABSTRACT The BIOFLOW-III Canada registry is a prospective, non-randomized, multi-center, observational all-comers registry designed to evaluate the safety and performance of the Orsiro SES in non-selected, real-world patients. A total of 250 patients (mean age 66.2 ± 10.8 years, 75.6% males, 30% diabetes) who underwent PCI with Orsiro SES, were enrolled at two high-volume Canadian centers. The overall rate of TLF at one year was 2.8% [95%CI 1.4-5.8%], whereas TLF rates were 4.1%, 3.2%, 8.3%, and 2.6% in patients with diabetes, small vessels ≤2.75 mm, CTO, and acute MI, respectively. No case of definite/probable ST was observed.

Abstract
PURPOSE The BIOFLOW-VI (Biotronik-Safety and Clinical Performance of the Drug Eluting Orsiro Stent in the Treatment of Subjects With De Novo Coronary Artery Lesions-VI) study evaluates the angiographic efficacy, clinical safety, and effectiveness of the ultrathin strut, biodegradable polymer sirolimus-eluting stent (BP-SES) compared with a durable polymer everolimus-eluting stent (DP-EES). This randomized controlled clinical trial was designed to enable approval of new drug-eluting stents in China. METHODS A total of 440 eligible patients from 11 sites with up to 2 de novo native coronary artery lesions were randomly assigned to receive either BP-SES (n = 220) or DP-EES (n = 220) from July 2014 to September 2016 in this prospective, multicenter, noninferiority trial. FINDINGS The primary end point of 9-month in-stent late lumen loss (LLL) was 0.05 (0.02) mm in the BP-SES group versus 0.07 (0.02) mm in the DP-EES group, with a mean difference of -0.02 mm (95% CI, -0.06 to 0.03; P = 0.44; Pnoninferiority < 0.0001). At 1 year, the target lesion failure rate (cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization) was similar between the 2 groups (BP-SES 2.3% vs DP-EES 1.4%; P = 0.50). No definite or probable stent thrombosis had occurred in any of the 2 treatment arms. IMPLICATIONS The randomized BIOFLOW-VI trial showed that BP-SES was noninferior to DP-EES with regard to the primary end point of 9-month in-stent LLL in a Chinese population.

Abstract
Advances in stent design and the development of bioresorbable polymers have allowed the development of novel stent technologies such as the Orsiro bioresorbable-polymer sirolimus eluting stent (BP-SES). Over several noninferiority trials, the BP-SES has demonstrated itself to be a safe and effective therapy for obstructive coronary artery disease. This article reviews the current evidence of the efficacy of the BP-SES and examines its performance in high-risk populations, such as patients presenting with ST-segment myocardial infarction, chronic total occlusions, diabetes, and small vessel disease.

Abstract
BACKGROUND The ULISSE registry evaluated the real-world performance of the Ultimaster® biodegradable polymer sirolimus-eluting stent (BP-SES) in a multicenter-independent cohort of patients undergoing percutaneous coronary intervention, including a large proportion of diabetes mellitus (DM) patients. METHODS In this subgroup analysis, 1,660 consecutive patients, 2,422 lesions, treated with BP-SES enrolled in the ULISSE registry were divided in two groups: DM (485 patients, 728 lesions) and non-DM (1,175 patients, 1,694 lesions). Primary endpoint was target lesion failure (TLF), a composite endpoint of cardiac-death, target-vessel myocardial infarction (TV-MI), and clinically driven target lesion revascularization (TLR) at 1-year. Secondary endpoint was TLR at 1-year. RESULTS At 1-year follow-up TLF occurred in 5% overall patients and was significantly higher in DM patients (8 vs. 3.7%; p = .001), due to more cardiac deaths (3.4 vs. 1.1%; p = .002). TLR occurred in 3.2% overall patients, and it was not significantly higher in DM compared to non-DM patients (4.4 vs. 2.8%; p = .114). The incidence of stent thrombosis was low and similar between groups (0.4 vs. 0.9%; p = .526). Insulin-treated DM (ITDM) patients showed higher rate of TLF as compared to non-ITDM patients (13 vs. 6.5%; p = .041), but similar rate of TLR (6 vs. 4%; p = .405). After adjustment for relevant comorbidities, DM was not significantly associated with TLF or cardiac death in patients undergoing BP-SES implantation. CONCLUSIONS This study is the first all-comers evaluation of BP-SES in DM patients. Our findings show that DM patients, mostly those with ITDM, still represent a vulnerable population and experience significantly higher rate of TLF. Overall BP-SES efficacy is considerable, although not statistically significant higher rate of TLR is still present in DM compared to non-DM patients.

Abstract
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.

Abstract
Recent stent developments aimed to reduce and eliminate the long-term inflammatory response include thinner struts, modifications to stent design and the development of bioresorbable polymers (BP). We aimed to summarize the main findings and to discuss the established and the potential benefits of the Orsiro BP sirolimus-eluting stents in everyday clinical use. We have reviewed the available evidence on the clinical performance of the Orsiro BP drug-eluting stents. Orsiro BP sirolimus-eluting stents is clinically proven and showed noninferiority against major drug-eluting stents and provides high safety and efficacy profile at long-term follow-up. Furthermore, it may be the preferred treatment option in specific subgroups as acute coronary syndrome, as shown in the BIOFLOW V trial.

Abstract
AIMS We aimed to corroborate clinical evidence on the safety and efficacy of the ultrathin-strut biodegradable-polymer sirolimus-eluting Orsiro stent in an all-comer population including high-risk subgroups. METHODS The nationwide, prospective, all-comer BIOFLOW-III Satellite Registry was conducted at 18 Italian sites. High-risk subgroups [diabetes, small vessels (≤2.75 mm), acute myocardial infarction (AMI), and chronic total occlusions (CTOs)] were prespecified. The primary endpoint was target lesion failure (TLF) at 12 months, a composite of cardiac death, target vessel myocardial infarction (MI), emergent coronary artery bypass graft, and clinically driven target lesion revascularization (TLR). RESULTS In all, 601 patients were enrolled (31.9% diabetes, 34.6% AMIs) with 736 lesions (37.2% small vessels, 5.7% CTOs, and 15.5% bifurcation lesions). Cumulative TLF rate at 12 months was 4.6% [95% confidence interval (CI) 3.2-6.6]: 6.9% (95% CI 4.1-11.6) in the diabetic patients, 5.0% (95% CI 2.7-9.1) in acute MI subgroup, 4.2% (95% CI 2.3-7.7) in small vessels, and 5.3% (95% CI 1.4-19.7) in CTOs. At 18-month follow-up, TLF, target vessel revascularization, and clinically driven TLR rates in the overall population were 5.2% (95% CI 3.7-7.4), 1.8% (95% CI 1.0-3.3), and 1.6% (95% CI 0.8-3.1), respectively. Probable stent thrombosis rate was 0.5% (95% CI 0.1-1.4), whereas no definite stent thrombosis was observed. CONCLUSIONS The study results confirmed the excellent clinical performance of the Orsiro drug-eluting stents at 18 months in the whole all-comer population and in the prespecified high-risk subgroups.

Abstract
Several new coronary stents have been, or soon will be, introduced in the United States. These stents incorporate certain characteristics, such as polymer-free drug coatings, ultrathin stent struts, bioresorbable polymers, and composite materials, that address currently unmet clinical needs to enhance acute stent performance, improve longer-term clinical outcomes, and obviate obligatory prolonged dual antiplatelet therapy. This article reviews the key and novel features of these stents.

Abstract
Cerebrovascular disease involves various medical disorders that obstruct brain blood vessels or deteriorate cerebral circulation, resulting in ischemic or hemorrhagic stroke. Nowadays, platinum coils with or without biological modification have become routine embolization devices to reduce the risk of cerebral aneurysm bleeding. Additionally, many intracranial stents, flow diverters, and stent retrievers have been invented with uniquely designed structures. To accelerate the translation of these devices into clinical usage, an in-depth understanding of the mechanical and material performance of these metal-based devices is critical. However, considering the more distal location and tortuous anatomic characteristics of cerebral arteries, present devices still risk failing to arrive at target lesions. Consequently, more flexible endovascular devices and novel designs are under urgent demand to overcome the deficiencies of existing devices. Herein, the pros and cons of the current structural designs are discussed when these devices are applied to the treatment of diseases ranging broadly from hemorrhages to ischemic strokes, in order to encourage further development of such kind of devices and investigation of their use in the clinic. Moreover, novel biodegradable materials and drug elution techniques, and the design, safety, and efficacy of personalized devices for further clinical applications in cerebral vasculature are discussed.

Biodegradable polymer drug-eluting stents versus second-generation drug-eluting stents in patients with and without diabetes mellitus: a single-center study. Cardiovasc Diabetol 2018; 17:114. [PMID: 30107794 PMCID: PMC6090623 DOI: 10.1186/s12933-018-0758-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2018] [Accepted: 08/11/2018] [Indexed: 01/14/2023] Open
Abstract
Background To improve outcomes in patients with diabetes mellitus (DM) undergoing percutaneous coronary intervention remain an unmet clinical need. The study aimed to evaluate the efficacy and safety of G2-DESs and BP-DESs in patients with and without DM in a single center in China. Methods A total of 7666 consecutive patients who exclusively had G2-DES or BP-DES implantation throughout 2013 in our center were studied. The primary efficacy endpoint was any target lesion revascularization (TLR), whereas the primary safety endpoint was a composite of death or myocardial infarction (MI) at 2-year follow-up. Results G2-DESs had a similar occurrence of death, non-fatal MI, TLR, stroke, and stent thrombosis compared with BP-DESs in patients with DM (all P > 0.05). The incidence of TVR and TLR was lower for G2-DESs than for BP-DESs in patients without DM (3.2% vs. 5.1%, P = 0.002; 2.2% vs. 4.5%, P < 0.001, respectively). Kaplan–Meier analysis also showed better TVR- and TLR-free survival rates for G2-DESs than for BP-DESs in patients without DM. Multivariate analysis showed that a BP-DES was an independent risk factor for TLR (hazard ratio 1.963, 95% confidence interval 1.390–2.772, P < 0.001) in patients without DM, which was not predictive of other components of major adverse cardiac events (P > 0.05). Conclusions G2-DESs have better efficacy, represented by a reduced risk of TLR, and similar safety compared with BP-DESs in patients without DM. G2-DESs have similar efficacy and safety compared with BP-DESs in patients with DM at 2-year follow-up.

Abstract
Background Drug-eluting stents (DES) compared to bare metal stents (BMS) have shown superior clinical performance, but are considered less suitable in complex cases. Most studies do not distinguish between DES and BMS with respect to their mechanical performance. The objective was to obtain mechanical parameters for direct comparison of BMS and DES. Methods In vitro bench tests evaluated crimped stent profiles, crossability in stenosis models, elastic recoil, bending stiffness (crimped and expanded), and scaffolding properties. The study included five pairs of BMS and DES each with the same stent platforms (all n = 5; PRO-Kinetic Energy, Orsiro: BIOTRONIK AG, Bülach, Switzerland; MULTI-LINK 8, XIENCE Xpedition: Abbott Vascular, Temecula, CA; REBEL Monorail, Promus PREMIER, Boston Scientific, Marlborough, MA; Integrity, Resolute Integrity, Medtronic, Minneapolis, MN; Kaname, Ultimaster: Terumo Corporation, Tokyo, Japan). Statistical analysis used pooled variance t tests for pairwise comparison of BMS with DES. Results Crimped profiles in BMS groups ranged from 0.97 ± 0.01 mm (PRO-Kinetic Energy) to 1.13 ± 0.01 mm (Kaname) and in DES groups from 1.02 ± 0.01 mm (Orsiro) to 1.13 ± 0.01 mm (Ultimaster). Crossability was best for low profile stent systems. Elastic recoil ranged from 4.07 ± 0.22% (Orsiro) to 5.87 ± 0.54% (REBEL Monorail) including both BMS and DES. The bending stiffness of crimped and expanded stents showed no systematic differences between BMS and DES neither did the scaffolding. Conclusions Based on in vitro measurements BMS appear superior to DES in some aspects of mechanical performance, yet the differences are small and not class uniform. The data provide assistance in selecting the optimal system for treatment and assessment of new generations of bioresorbable scaffolds. Trial registration: not applicable

Abstract
BACKGROUND Traditional study design submitted to the Food and Drug Administration to test newer drug-eluting stents (DES) for marketing approval is the prospective randomized controlled trial. However, several DES have extensive clinical data from trials conducted outside the United States that have led to utilization of a novel design using the Bayesian approach. This design was proposed for testing DES with bioresorbable polymer compared with DES most commonly in use today that use durable polymers for drug elution. STUDY DESIGN AND OBJECTIVES This prospective, multicenter, randomized, controlled trial is designed to assess the safety and efficacy of the Orsiro bioresorbable polymer sirolimus-eluting stent (BP SES). Up to 1,334 subjects with up to 3 de novo or restenotic coronary artery lesions who qualify for percutaneous coronary intervention with stenting will be randomized 2:1 to the BP SES versus the Xience durable polymer everolimus-eluting stent (DP EES). Data from this trial will be combined with data from 2 similarly designed trials that also randomize subjects to BP SES and DP EES (BIOFLOW II, N=452 and BIOFLOW IV, N=579) by using a Bayesian approach. The primary end point is target lesion failure at 12 months post index procedure, defined as cardiac death, target vessel myocardial infarction, or clinically driven target lesion revascularization, and the primary analysis is a test of noninferiority of the BP SES versus DP EES on the primary end point according to a noninferiority delta of 3.85%. Secondary end points include stent thrombosis and the individual components of target lesion failure. Subjects will be followed for 5 years after randomization. CONCLUSIONS The BIOFLOW V trial offers an opportunity to assess clinical outcomes in patients treated with coronary revascularization using the Orsiro BP SES relative to a commonly used DP EES. The use of a Bayesian analysis combines a large randomized cohort of patients 2 two smaller contributing randomized trials to augment the efficiency of the comparison.

Abstract
BACKGROUND Drug-eluting stents with biodegradable polymer might be particularly useful in diabetic patients who are at increased risk for target lesion/target vessel revascularization. We therefore aimed at assessing the safety and performance of a biodegradable polymer sirolimus-eluting stent (BP-SES) in combination with comprehensive optimal medical therapy following coronary interventions. METHODS This prospective, multicenter registry was conducted at six centers in Israel. Aside of stent treatment, we aimed for an LDL-C level<70mg/dl; at one and six months post-intervention a diabetic consultancy was required, and follow-up data were collected at six and twelve months. The primary outcome measure was target vessel failure, a composite of cardiac death, target-vessel myocardial infarction and clinically driven target vessel revascularization. Secondary outcomes were target lesion failure, its individual components, and stent thrombosis. RESULTS From August 2013 until May 2014, 120 diabetic patients with 158 lesions were treated with a BP-SES. Mean age was 63.9±9.2years, 27.5% were insulin dependent, 28.3% had a history of myocardial infarction, and 47.5% had prior coronary interventions. By visual estimation, lesions were 3.0±0.5mm in diameter and 15.2±7.4mm long; mean stent diameter and length were 3.0±0.5mm and 19.2±6.8mm. Target vessel failure and target lesion failure at 12months occurred in seven (6.4% [95% CI: 3.1-13.0]) and four patients (3.5% [95% CI: 1.3-9.2]), respectively, and definite stent thrombosis in one patient (1.0% [95% CI: 0.1-7.0]). CONCLUSION Treatment with a BP-SES demonstrated excellent target-vessel and target-lesion revascularization rates in a high-risk diabetic patient population undergoing catheter-based revascularization followed by intensified medical care. ANNOTATED TABLE OF CONTENTS In 120 high-risk diabetic patients with coronary artery stenosis, treatment with the Orsiro sirolimus-eluting stent with biodegradable polymer and comprehensive antidiabetic therapy resulted in excellent clinical outcomes. Target vessel revascularization occurred in 6.4% of patients and target lesion revascularization in 3.5%.

Abstract
Drug-eluting stents (DES) have been shown to significantly reduce clinical and angiographic restenosis compared to bare metal stents (BMS). The polymer coatings on DES elute antiproliferative drugs to inhibit intimal proliferation and prevent restenosis after stent implantation. Permanent polymers which do not degrade in vivo may increase the likelihood of stent-related delayed arterial healing or polymer hypersensitivity. In turn, these limitations may contribute to an increased risk of late clinical events. Intuitively, a polymer which degrades after completion of drug release, leaving an inert metal scaffold in place, may improve arterial healing by removing a chronic source of inflammation, neoatherosclerosis, and/or late thrombosis. In this way, a biodegradable polymer may reduce late ischemic events. Additionally, improved healing after stent implantation could reduce the requirement for long-term dual antiplatelet therapy and the associated risk of bleeding and cost. This review will focus on bioabsorbable polymer-coated DES currently being evaluated in clinical trials.

Abstract
Objective. The objective of the MANIPAL-FLEX study was to evaluate the feasibility, preliminary safety, and efficacy of the Supraflex sirolimus-eluting stent (SES) implantation, in de novo coronary artery disease, using clinical and quantitative coronary angiography (QCA) follow-ups. Methods. This was a prospective, nonrandomized, multicenter, single-arm study that enrolled 189 patients with de novo coronary artery disease who were treated with the Supraflex SES. Of 189 patients enrolled, the first 61 consecutive patients who consented to a 9-month follow-up evaluation by QCA, irrespective of presence of symptoms, were to be followed up with angiography at 9 months. The primary endpoint of the study was target lesion failure (TLF), including cardiac death, myocardial infarction, and target lesion revascularization during 12-month follow-up after the index procedure. Results. The mean age of the study population was 58 ± 11 years, with 51.3% (97/189) of hypertensive patients. Total of 66 lesions, analyzed by offline QCA, showed good scaffolding of the target vessel with in-stent late lumen loss at 9 months of 0.18 ± 0.23 mm. The observed TLF at 30-day, 6-month, and 12-month follow-up were 2 (1.1%), 6 (3.2%), and 10 (5.3%), respectively. Conclusion. This study provides preliminary evidence for the feasibility, safety, and efficacy of the Supraflex sirolimus-eluting stent.

Abstract
BACKGROUND The aim of this study was to assess the safety and the efficacy of the novel sirolimus-eluting Prolim® stent with a biodegradable polymer in the all-comers population. METHODS We prospectively enrolled all patients with stable coronary artery disease or acute coronary syndrome treated with Prolim® stent between January and December 2013 in two interventional cardiology centers in Poland. Angiographic control was planned at 12 months, in which 15 % of patients (randomly chosen) underwent optical coherence tomography imaging. The primary end-point was the cumulative rate of cardiac death, myocardial infarction, and target lesion revascularization at 12 months. RESULTS There were 204 patients enrolled, in whom 238 Prolim® stents were deployed (1.17 stent per patient). The mean age was 68 ± 10 years and 32.8 % were females. The examined stent was implanted in 5.9 % in STEMI patients, in 21.6 % - in NSTE-ACS and in 72.5 % - in patients with stable coronary artery disease. The Prolim® stent was most frequently implanted in right coronary artery (38.2 %) followed by left anterior descending artery (34.0 %). The cumulative major adverse cardiovascular events rate at 12 months was 6.9 %, and the clinically-driven target lesion revascularization rate - 5.4 %. At 12 months in quantitative coronary angiography the late lumen loss was 0.21 ± 0.18 mm, and in optical coherence tomography the mean neointima burden was 24.6 ± 8.6 %. CONCLUSIONS Sirolimus-eluting Prolim® stent with a biodegradable polymer is a feasible device with a very good safety profile and long-term clinical effectiveness.
