Advances in drug-eluting stent technology have continued to improve clinical outcomes for patients undergoing percutaneous coronary intervention (PCI). The Boston Scientific stent platform has evolved from the 316L stainless steel Express™ stent, to the 316L stainless steel Liberté™ stent, to the cobalt–chromium PROMUS™ stent and, finally, to the platinum–chromium (PtCr) stent series. The PtCr platform, which uses the Element architecture, is designed to have improved deliverability, radiopacity, radial strength and recoil resistance compared with existing stainless steel or cobalt–chromium stents. This review discusses the key points in Boston Scientific’s development programme, which has culminated in the newest generation of coronary stent systems: the PtCr bare-metal OMEGA™ stent, the PtCr paclitaxel-eluting TAXUS Element™ (ION™) stent and the PtCr everolimus-eluting PROMUS Element™ stent systems.

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).

Postoperative coronary artery complications after Bentall procedures are well recognised but are rare and potentially fatal. There have been only five cases documenting percutaneous coronary intervention (PCI) for right coronary artery (RCA) involvements after button Bentall procedures. We describe a case of postoperative silent myocardial ischaemia in a 72-year-old man who underwent the button Bentall procedure for a right sinus of Valsalva aneurysm. On postoperative day 15, an RCA complication was incidentally detected by follow-up multidetector CT. Coronary angiography showed proximal RCA kinking, which was not an anastomosis but a native coronary artery. The patient underwent a successful PCI with drug-eluting stent implantation. We reviewed six cases consisting of this case and five previous cases treated with PCI. These cases enhance the recognition of potential RCA complications after the button Bentall procedure.
