“…The primary safety and efficacy trials meriT-1 [18] and meriT-2 [19] and, more recently, the observational post-marketing multisite registry meriT-3 [14] reported low rates of major adverse cardiovascular events (MACEs) and late stent thrombosis. Finally, the randomized meriT-5 trial [20] demonstrated that BM was non-inferior to the XIENCE DES at 9-month follow-up.…”

Background: Treatment of long coronary stenoses (LCS) with long tapered drug-eluting stents (LT-DES) would offer clinical and economic benefits. However, the feasibility of an interventional strategy based upon the systematic LCS treatment with an LT-DES has not been evaluated so far. Methods: We performed a multicenter prospective study including consecutive patients with: 1) An LCS > 25 mm at coronary angiography; 2) An attempt to fix the LCS with a single BioMime Morph™ stent, a novel LT-DES available from 30 to 60 mm long. The primary efficacy endpoint was procedural success. The secondary safety endpoints were post-procedural TIMI3 flow, stent detachment during delivery, acute stent thrombosis and in-hospital mortality. Results: From February 2017 to March 2018, we recorded 272 patients with an LCS and an attempt to deploy an LT-DES during percutaneous coronary intervention (PCI) (69.3 ± 11.4 years, 75.7% males, 25.7% diabetic and 43.8% with acute coronary syndromes, mean LCS length 48.8 ± 9.5 mm). LT-DES deployment was successful in 262 patients (96.3%), and failure occurred without stent detachment or other complications. Final TIMI3 flow was present in 270 (99.3%) patients. In-hospital death occurred in five patients (1.8%), with no case of acute stent thrombosis, recurrent myocardial infarction or repeated revascularization. Conclusion: In this real-world study, a strategy of fixing LCS with a single LT-DES was feasible and safe, with a high rate of procedural success and a low rate of in-hospital complications. More extensive randomized studies are warranted to assess the potential clinical and economic benefits of LT-DES.

“…Series of randomized trials have demonstrated the clinical benefit of ultrathin DES in patients with CHD. [25][26][27] Moreover, according to a meta-analysis study, <70 µm ultrathin-strut DESs, including MiStent, improved 1-year clinical outcomes, in comparison with thicker strut DESs. [28] These results proved that the ultrathin strut of MiStent additionally provides beneficial effect for patients with CHD.…”

Objective: Data comparing the outcomes of MiStent (Micell Technologies, Durham, North Carolina, USA) microcrystalline biodegradable polymer (BP) drug-eluting stent (DES) and those of another post-marketing BP-DES, TIVOLI (EssenTech, Beijing, China) are rare. This study sought to compare the angiographic efficacy and clinical outcomes of the microcrystalline BP sirolimus-eluting stent (SES) system MiStent and those of TIVOLI BP-SES. Methods: The DESSOLVE-C trial was a prospective, single-blinded, multicenter, randomized trial (NCT02448524), which randomly assigned patients with de novo coronary lesions to receive MiStent or TIVOLI BP-SES by a 1:1 ratio. The primary endpoint was a non-inferiority comparison of in-stent late lumen loss (LLL) by quantitative coronary angiography at 9 months. The secondary endpoint was device-related clinical cardiovascular composite events (target lesion failure (TLF), composite of cardiac death, target vessel myocardial infarction (MI), and clinically driven target lesion revascularization) and 1-year outcomes. Results: A total of 428 patients (216 patients in the MiStent group and 212 patients in the TIVOLI group) were enrolled and included in an intention-to-treat analysis. MiStent was not only non-inferior but superior to TIVOLI for in-stent LLL at 9 months ((0.23 ± 0.37) mm vs. (0.34 ± 0.48) mm, P for non-inferiority <0.001, P for superiority = 0.02). Although without significant difference, the rate of TLF in MiStent was quantitatively lower than that in TIVOLI (3.70% vs. 6.60%; P = 0.17). Conclusion: Compared with TIVOLI BP-SES, the MiStent system was superior in in-stent LLL at 9 months and had a comparable clinical benefit at 1 year in de novo coronary lesions.

“…Furthermore, the lower-than-previously-reported overall TLR rates of 1.0% in the control DP-EES group (where other randomized trials consistently have reported rates of 2%-5% at 12 months using the same definitions), is significantly underpowered and not prespecified to make this comparison reliable. [39][40][41][42][43][44][45] While between-trial differences are difficult to ascertain, one important factor in our study is that a significant proportion of clinical follow-up was performed between January and July 2020 at the peak of the coronavirus disease 2019 (COVID-19) pandemic. Whether possible pandemic-related hospital presentation delays or avoidance contributed to lower-than-expected TLR rates cannot be fully evaluated.…”

Novel Supreme Drug-Eluting Stents With Early Synchronized Antiproliferative Drug Delivery to Inhibit Smooth Muscle Cell Proliferation After Drug-Eluting Stents Implantation in Coronary Artery Disease: Results of the PIONEER III Randomized Clinical Trial

et al. 2021

Background: Accelerated endothelial healing after targeted antiproliferative drug delivery may limit the long-term inflammatory response of drug eluting stents (DES). The novel Supreme TM DES (Supreme) is designed to synchronize early drug delivery within 4-6 weeks of implantation, leaving behind a pro-healing permanent base layer. Whether the Supreme DES is safe and effective in the short term and can improve long term clinical outcomes is not known. Methods: In an international 2:1 randomized single-blind trial, we compared treatment with Supreme DES to durable polymer everolimus-eluting stents (DP-DES) in patients with acute and chronic coronary syndromes. The primary endpoint was target lesion failure (TLF) - a composite of cardiac death, target vessel myocardial infarction, or clinically-driven target lesion revascularisation (TLR). The trial was designed to demonstrate non-inferiority (margin of 3.58%) of the Supreme DES at 12 months compared to DP-DES (clinicaltrials.gov-NCT03168776). Results: From October 2017 to July 2019, a total of 1629 patients were randomly assigned (2:1) to the Supreme DES (N=1086) or DP-DES (N=543). At 12 months, TLF occurred in 57 of 1057 patients (5.4%) in the Supreme DES group and in 27 of 532 patients (5.1%) in the DP-DES group (Absolute Risk Difference 0.32%, 95%CI [-1.87%, 2.5%]; p non-inferiority =0.002]. There were no significant differences in rates of device success, clinically driven TLR or stent thrombosis at 12 months, and the safety composite of CV Death and TV MI was 3.5% vs 4.6%; HR [95.0% CI] 0.76 [0.46, 1.25] with Supreme DES compared to DP-DES, though rates of combined clinical and non-clinical driven TLR at 12 months were higher with Supreme DES. Conclusions: Among patients with acute and chronic coronary syndromes undergoing percutaneous coronary intervention, the Supreme DES proved to be non-inferior to the standard DP-DES.

Randomised comparison of a biodegradable polymer ultra-thin sirolimus-eluting stent versus a durable polymer everolimus-eluting stent in patients with de novo native coronary artery lesions: the meriT-V trial

Abstract: In the treatment of de novo native coronary artery lesions, the biodegradable polymer ultra-thin SES (BioMime) was non-inferior to a durable polymer EES (XIENCE) at nine-month follow-up. Further studies powered for clinical endpoints are needed.
