First-generation drug-eluting stents have raised concerns regarding the risk of late and very late stent thrombosis compared with bare metal stents and require prolonged dual antiplatelet therapy. Despite extensive investigations, the physiopathology of these late events remains incompletely understood. Aside from patient- and lesion-related risk factors, stent polymer has been cited as one of ...
BACKGROUND Neointimal hyperplasia plays a pivotal role in the pathogenesis of in-stent restenosis in patients undergoing percutaneous coronary interventions. Drug-eluting balloons are a promising tool to prevent restenosis after coronary angioplasty. Moreover, an increased knowledge of the pathophysiology of restenosis my help improve therapeutic strategies. METHODS/DESIGN We present the desi...
High risk angioplasty with drug eluting stent placement into an unprotected left main coronary artery in a heart transplant recipient with allograft vasculopathy is reported. Ten month angiographic follow up is reported. The literature is reviewed and current methods of revascularisation are described in detail. This is the first report of drug eluting stent use in this clinical situation.
Drug-eluting balloon (DEB) with angioplasty a paclitaxel-coated balloon catheter is an effective treatment option in patients with in-stent restenosis (ISR) after a drug-eluting stent (DES). We describe a case in which 'no-reflow' phenomenon developed after DEB angioplasty of a DES ISR lesion. Coronary flow was restored after intracoronary administration of nicorandil.
INTRODUCTION AND OBJECTIVES The interventional cardiologist chooses a specific stent type based on the risk-benefit profile for each case. In general, drug-eluting stents should be considered in all clinical conditions, except if there are concerns or contraindications for prolonged dual antiplatelet therapy. The aim of this work was to describe the use of bare-metal vs. drug-eluting stents in ...
The development of coronary stents represents a major step forward in the treatment of obstructive coronary artery disease since the introduction of percutaneous coronary intervention. The initial enthusiasm for bare metal stents was, however, tempered by a significant incidence of in-stent restenosis, the manifestation of excessive neointima hyperplasia within the stented vessel segment, ultim...
Stent thrombosis in Sweden: a report from the Swedish Coronary Angiography and Angioplasty Registry.
BACKGROUND The objective was to evaluate the role of risk factors and stent type for stent thrombosis (ST) using a large real world registry. METHODS AND RESULTS We evaluated all consecutive coronary stent implantations in Sweden from May 1, 2005, to June 30, 2007. All cases of ST, documented in the Swedish coronary angiography and angioplasty registry until September 21, 2008, were analyzed....
BACKGROUND Patients with coronary total occlusions are at especially high risk for restenosis and new revascularizations. Sirolimus-eluting stents dramatically improved the clinical outcome of this subset of patients in randomized trials, but other drug-eluting stents, mainly the everolimus-eluting stent (currently the most frequently used stent), have not yet been evaluated in patients with co...
a w a t t a c s t v k p s ne of the most dreaded complications after percutaneous oronary arterial angioplasty is stent thrombosis. This erious untoward event usually results in acute myocardial nfarction with high mortality. Stent thrombosis often ocurs early, within 30 days of implantation, in patients who eceive bare metal coronary arterial stents. However, paients undergoing drug-eluting st...
