The future of coronary stent design REVIEW aRTICLE

چکیده
The methodology in interventional cardiology has historically evolved from diagnostic coronary angiography to balloon angioplasty, to the use of bare metal stents (BmSs), to their refinement to drug-eluting stents with a durable polymer, and is now on the verge of drug-eluting stents with further developed drug delivery approaches such as reservoir technology and the use of bioresorbable polymers. Two decades ago, coronary stents were stainless steel (316L) tubes designed to prevent the acute complication of balloon angioplasty – acute vessel closure. Ever since, efforts have been directed, not only to improve acute procedural outcomes, but also towards long-term outcomes and prognosis. many lessons learned in the past are still relevant for stent design today and the future.

Management of a large coronary artery aneurysm with graft-coated stent during the acute phase of myocardial infarction
Coronary aneurysms in adults are rare clinical entities. Herein, we presented a 54-year-old man who was admitted with an acute extensive anterior myocardial infarction. The emergency coronary angiography revealed an isolated large aneurysm at the proximal segment of the left anterior descending coronary artery. The patient was successfully treated with a graft-coated stent
متن کاملOverview of Intracoronary Brachytherapy for in-Stent Restenosis of a Drug-Eluting Stent
Percutaneous coronary intervention with stenting is considered recently as the most common procedure for the treatment of symptomatic coronary. The article reviewed 41 studies published during 1997-2019 on intracoronary brachytherapy for in-stent restenosis of a drug-eluting stent. Intracoronary radiation therapy was finally confirmed in the setting of in-stent restenosis using as adjunctive th...
متن کاملAssociation of G22A variant of Adenosine Deaminase gene with coronary in-stent restenosis in coronary artery patients receiving drug-eluting stent
In-stent restenosis (ISR) is regarded as the main problem in the utilization of stents in the treatment of coronary artery atherosclerotic stenosis in percutaneous coronary intervention (PCI). This study investigated the possible role of the G22A variant of the Adenosine Deaminase gene (ADA) in the development of ISR. In this study, 91 patients who underwent PCI were divided into two groups of ...
