Coronary Brachytherapy and Restenosis
Heart Drug, 2001The antiproliferative effects of radiotherapy have been used clinically for over 100 years to treat several benign disorders. More recently, several experimental studies have convincingly demonstrated that the use of intracoronary radiotherapy results in marked modulation of the restenotic process.

Preventing Coronary Restenosis and Complications
New England Journal of Medicine, 1997Interventions aimed at opening occluded coronary arteries continue to evolve. Two fundamental problems that limit the clinical efficacy of coronary interventions are restenosis after coronary angio...

Consequences of restenosis after coronary angioplasty
International Journal of Cardiology, 1991The consequences of restenosis after angioplasty were evaluated in 466 patients who had coronary angiography 3 to 12 months after successful coronary angioplasty and were followed long term. The 236 subjects with restenosis resembled the 230 without restenosis with respect to age, sex, presence of multivessel disease, mean ejection fraction, prior ...

Management of restenosis after coronary intervention
American Heart Journal, 1996Coronary restenosis has proven to be the "Achilles heel" of percutaneous coronary interventions, frequently leading to repeated procedures. The pathogenesis of restenosis can be divided into four phases: early elasic recoil (hours to days), mural thrombus formation (hours to days), neointimal proliferation and extracellular matrix formation (weeks ...

Treatment options for coronary stent restenosis
Comprehensive Therapy, 1999Treatment of in-stent restenosis with balloon angioplasty alone is adequate for focal lesions but is associated with a 50% recurrence rate for diffuse lesions. For diffuse in-stent restenosis, debulking with atherectomy or laser can significantly reduce the recurrence rate.

Coronary dissection: A predictor of restenosis?
American Heart Journal, 1988To determine if arterial dissection resulting from transluminal coronary angioplasty (TCA) leads to a greater incidence of restenosis, 273 consecutive patients who had undergone TCA with at least 1 year of follow-up were examined. Success was graded as a greater than or equal to 20% increase in intraluminal diameter.

Restenosis: Directional Coronary Atherectomy
1992The concept of atherectomy was developed by J. B. Simpson to overcome some of the limitations of PTCA with the hypothesis that removal of tissue from an obstructed vessel would create a smooth and wide lumen [1, 2]. A smooth, wide lumen without dissection may prevent acute occlusion or reduce thrombus formation, thus improving the acute outcome ...

Prevention of restenosis after coronary angioplasty
Current Opinion in Cardiology, 2004Despite numerous advances in coronary interventional techniques, the frequent occurrence of restenosis continues to plague interventional cardiology. With the widespread use of drug-eluting stents, there is a need to reexamine critically the roles of the various interventional techniques currently available.Drug-eluting stents have dramatically reduced

Restenosis after Percutaneous Transluminal Coronary Angioplasty
Acta Radiologica, 1992Restenosis after percutaneous transluminal coronary angioplasty was demonstrated in 61 (29%) of 210 successfully treated patients. Mostly it occurred within 4 months after treatment and in arteries less than 3 mm in diameter. Careful clinical follow-up is therefore particularly important early after angioplasty of smaller arteries.
