Sirolimus Eluting Stent

The sirolimus-eluting stent (SES) Cypher was the first commercially available drug-eluting stent. The use of this stent has resulted in significantly lower rates of restenosis and lesion revascularization compared to bare metal stents and balloon angioplasty. In this review, angiographic and clinical outcomes in patients treated with SES are compared to those treated with bare metal stents and other drug-eluting stents. Furthermore, efficacy and safety outcomes of SES in complex lesions (left main stenosis, bifurcation lesions, chronic total occlusions, long lesions and small vessels) and high risk populations (diabetes and acute myocardial infarction) are presented.

Background: Aim of the study was to evaluate the primary procedural success of percutaneous coronary intervention of unprotected left main coronary artery stenosis using either Bare-metal stents or drug eluting stent. Methods: Total 33 patients were enrolled in this very preliminary non-randomized prospective cohort study. Among them, Male: 25 and Female: 8. Total 35 stents were deployed. Mean age were for Male: 59 yrs, for Female: 62 yrs. Associated coronary artery diseases risk factors were dyslipidemia, High Blood pressure, Diabetes Mellitus, Positive family history for coronary artery diseases and smoking. Results: Among the study group; 26 (78%) were Dyslipidemic, 24(70%) were hypertensive; 17 (51.5%) patients were Diabetic, 11(33%) were smoker and 7(21%) patients had family history of Ischaemic heart disease. Female patients were more obese (BMI M 26: F 27) and developed coronary artery diseases in advance age. Common stented territory were left main: 20 (60%), Left main to left anterior descending artery 7 (22%) and Left main to left circumflex artery 6 (18%). Average length and diameter of stent was 3.5 and 18 mm respectively. Stent used: Bare Metal Stent 5 (15%), Drug Eluting Stent: 28 (85%). Among the different Drug Eluting Stents, Everolimus eluting stents were 11 (39.3%), Sirolimus eluting 10(35.7%), Paclitaxel eluting 3 (10.7%), Biolimus eluting 3 (10.7%) and Zotarolimus eluting1 (3.6%). In the present study, overall survival outcome was 94% (31 patient), mortality of cardiac cause 3% (1 patient) and 1 patient (3%) died of hepatocellular carcinoma. Conclusion: Our study has shown that percutaneous coronary intervention of the unprotected left main is a safe and effective alternative to Coronary Artery Bypass Graft (CABG).

In Stent Restenosis

The coronary artery stent has been widely used in clinic. In-stent restenosis was mainly caused by the excessive proliferation of smooth muscle cell and the inflammation due to the metal ion released from stent scaffold of the drug-eluting stent. Thus, to reduce the in-stent restenosis and promote the vascular endothelialization have become a hot research point in this area. In this paper, a nano-TiO2 ceramic coating was deposited on 316L stainless steel to reduce the metal ion release and to inhibit the inflammation reaction. An endothelia cell selective adhesion peptide Arg-Glu-Asp-Val (REDV) coating was prepared on the ceramic coating by a polydopamine technology to promote the endothelialization. The corrosion test indicated that nano-TiO2 ceramic film could effectively decrease the nickel ion released from 316L stainless steel. REDV/TiO2 coating could promote the endothelial cell adhesion and proliferation, meanwhile REDV/TiO2 coating could also increase the nitric oxide concentration. Bare metal stent, TiO2-coated stent and REDV/TiO2-coated stent were implanted in the iliac arteries of rabbit model. In-stent restenosis and re-endothelialization were evaluated at 28 days post-implantation of the stents. The results showed that REDV/TiO2-coated stents could effectively reduce in-stent restenosis and promote re-endothelialization in comparison with TiO2-coated drug-eluting stent and bare metal stent. These results suggest that REDV/TiO2-coated drug-eluting stent maybe a good choice of the application for coronary artery disease.

And Control

Stent thrombosis remains the primary cause of death after percutaneous coronary interventions (PCI). Despite modern concepts of PCI, stent thrombosis occurs in 0.5% -2% of elective procedures and even 6% of patients with the acute coronary syndrome (ACS). Stent thrombosis most often develops within the first 48 hours after the PCI, and rarely after a week of stent implantation. Angiographically documented late (>6 months) thrombosis of coronary bare-metal stent (BMS) is rare, because the stent endothelialization is considered to be completed after four weeks of the intervention. Our patient is a 41 year old male and he had BMS thrombosis 345 days after the implantation, which was clinically manifested as an acute myocardial infarction in the inferoposterolateral localization. Stent Clinical Centre of Serbia, Belgrade thrombosis occurred despite a long term dual antiplatelet therapy and control of known risk factors. Thrombolytic therapy (Streptokinase in a dose of 1 500 000 IU) was not successful in reopening the occluded vessel, so the flow through the coronary artery was achieved by rescue balloon angioplasty, followed by implantation of drug eluting stent in order to prevent restenosis.
