Coronary In-Stent Restenosis: Assessment with CT Coronary Angiography
Radiology, 2012To compare accuracy and radiation exposure of a new computed tomographic (CT) scanner with improved spatial resolution (scanner A) with those of a CT scanner with standard spatial resolution (scanner B) for evaluation of coronary in-stent restenosis (ISR) by using invasive coronary angiography (ICA) and intravascular ultrasonography (US) as reference ...

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...

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.

Coronary restenosis is the answer of the arterial wall to a mechanical violation through balloon angioplasty, bare-metal (BM) stent implantation or rotational atherectomy through repeated narrowing. It has great clinical and prognostic relevance and occurs in approximately 30% of non-coated stents and in 10% of coated coronary stents. The wound healing

Coronary restenosis: Evaluation of a restenosis injury index in a swine model
American Heart Journal, 1993To 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.

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 ...

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 ...

Restenosis in intervened coronaries with hyperhomocysteinemia (RICH)
American Heart Journal, 2003Controversy exists regarding the contribution made by elevated serum homocysteine evels in raising the risk of restenosis after percutaneous coronary interventions. The objective of this study was to determine whether elevated homocysteine evels increase the risk of restenosis.Two hundred and two consecutive patients undergoing percutaneous coronary ...

Treatment of coronary artery in-stent restenosis
Expert Review of Cardiovascular Therapy, 2017Although drug-eluting stents (DES) have significantly reduced the incidence and prevalence of coronary in-stent restenosis (ISR), ISR still occurs in approximately 10% of patients in real-world practice. Areas covered: The development of newer generations of DES, drug-coated balloons (DCB) and increased use of intracoronary imaging have improved our ...

Pathophysiology of coronary artery in‐stent restenosis
Acute Cardiac Care, 2007In-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.
