Preventing Coronary Restenosis and Complications

New England Journal of Medicine, 1997
Interventions 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...

The Porcine Model of Coronary Restenosis

2001
Human coronary restenosis remains an elusive problem, and a major limitation of all percutaneous interventional coronary revascularization procedures, despite intracoronary stenting (1–9). Restenosis has recently gained even greater importance, since trials comparing PTCA with coronary bypass surgery (BARI, EAST, CABRI) suggest that angioplasty is ...

Effects of endovascular radiation from a beta-particle-emitting stent in a porcine coronary restenosis model. A dose-response study.

Circulation, 1996
BACKGROUND Neointimal formation causes restenosis after intracoronary stent placement. Endovascular radiation delivered via a stent has been shown to reduce neointimal formation after placement in porcine and rabbit iliac arteries.

Treatment options for coronary stent restenosis

Comprehensive Therapy, 1999
Treatment 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.

Contributions of frequency distribution analysis to the understanding of coronary restenosis. A reappraisal of the gaussian curve.

Circulation, 1996
BACKGROUND Clinical restenosis after balloon angioplasty can be categorized by use of dichotomous terms based on the presence or absence of recurrent myocardial ischemia.

Management of restenosis after coronary intervention

American Heart Journal, 1996
Coronary 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 ...

Coronary restenosis: Evaluation of a restenosis injury index in a swine model

American Heart Journal, 1993
To investigate the mechanisms of restenosis and detect useful interventions to prevent it, reliable quantitative measurements must be evaluated. Coronary arteries of domestic and minipigs (n = 18) were mechanically injured by balloon overstretching and killed at different intervals (2 to 25 weeks) after quantitative angiographic analysis.

Pathophysiology of coronary artery in‐stent restenosis

Acute Cardiac Care, 2007
In-stent restenosis reflects the interaction of a cascade of molecular and cellular events occurring within the vessel wall. Coronary stenting induces localized injury to the vessel wall, which leads to the release of thrombogenic, vasoactive, and lymphocytes mitogenic factors that result in processes causing re-narrowing at the injured site.

Restenosis After Coronary Balloon Angioplasty

Annual Review of Medicine, 1991
A recurrence of stenosis (restenosis) following successful coronary angioplasty continues to be a frequent problem limiting the long-term efficacy of the procedure. An overexuberant reparative response to the arterial injury induced by balloon dilatation leads to intimal hyperplasia, the major mechanism responsible for restenosis. Although none has yet
