FAME and Coronary Stent Investigations

Association 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 ...

Coronary stent fracture.

E756 CMAJ, August 9, 2011, 183(11) © 2011 Canadian Medical Association or its licensors An 82-year-old man presented with fa tigue and was diagnosed with bradycardia, associated with third-degree heart block. The patient had required implantation of bare-metal stents in each of the major epicardial vessels nine years previously, but was currently free of angina. Because of a modest rise in his ...

Late coronary stent thrombosis.

Introduced 20 years ago,1 coronary artery stents have improved the safety and particularly the efficacy of percutaneous coronary interventions (PCIs).2 Abrupt vessel closure, complicating 6% to 8% of balloon angioplasty procedures, was associated with a 5% mortality, 40% rate of myocardial infarction (MI), and 40% rate of emergency coronary artery bypass grafting.3 Stents significantly reduced ...

Coronary stent entrapment

A 64-year-old woman with a history of coronary artery bypass and coronary angioplasty with unexpanded stent entrapment blocked in the circumflex coronary artery and left main is now presenting with crescendo angina pectoris. The Department of Cardiovascular Surgery established that a new surgical intervention presents a very high risk. In this condition, we decide for elective percutaneous coro...
