New Stent Technologies
Balloon angioplasty of the coronary arteries was first developed in the 1970s as an alternative means of revascularization to coronary artery bypass surgery. A major drawback with balloon angioplasty alone was the high rate of abrupt vessel closure resulting from acute arterial recoil and coronary artery dissection. The introduction of bare metal stents (BMS) in the early 1990s revolutionized p...
متن کاملNew stent technologies.
Coronary stents were developed to overcome the two main limitations of balloon angioplasty, acute occlusion and long-term restenosis. Coronary stents can tack back intimal flaps and seal the dissected vessel wall, thereby treating acute or threatened vessel closure after unsuccessful balloon angioplasty. After successful balloon angioplasty, stents can prevent late vessel remodeling (chronic ve...
متن کاملStent Thrombosis: Incidence, Predictors and New Technologies
Some concerns have been raised regarding the risk of late and very late stent thrombosis (ST) following drug-eluting stent implantation. Despite remaining an uncommon complication of percutaneous coronary intervention, when ST occurs, it can be catastrophic to the individual, commonly presenting as acute ST elevation myocardial infarction or sudden cardiac death. The incidence and predictors of...
متن کاملNovel stent and drug elution technologies
To address concerns of late and very late stent thrombosis associated with first generation drug-eluting stent technology, novel approaches are being tested including stents with bioabsorbable polymers (including Biomatrix FlexTM, NoboriTM and SynergyTM), polymer-free drug delivery systems (including BiofreedomTM and Yukon®) and drug-eluting balloons (including Sequent PleaseTM, Dior® II and Pa...
