Coronary stent implantation is being performed in an increasing number of patients with a wide spectrum of clinical and lesion characteristics. A variety of stent designs are now available and continuous efforts are being made to improve the stent placement procedure. The objective of this study was...
The long term outcome of stent implantation is affected by a process called in-stent restenosis(ISR).In-stent resteno- sis remains a problem that is the chest pain after coronary stent placement.Multiple contributory factors have been identified,but clear understanding of the overall underlying mech...
METHODS: All patients with successful coronary stent placement were eligible for this study unless they had had a major adverse cardiac event during the 1st 30 days after the procedure. Of the 1,349 eligible patients (1,753 lesions), follow-up angiography at 6 months was performed in 80.4% ...
Additionally, approximate entropy values were estimated to assess the differences induced by the stent placement procedure to the acoustic signature of the signals in the time domain. The groups were identified with this method with 82% sensitivity and 64% specificity (using the power ratio method)...
1.A device used to support a bodily orifice or cavity during skin grafting or to immobilize a skin graft following placement. 2.A short tubular device made of wire mesh or fabric that is placed permanently in an anatomical passage, usually an artery during angioplasty, to keep it open after...
an obstructed coronary artery and involves passing a catheter through the skin and into a blood vessel (as of the groin) to the site of obstruction so the blockage can be compressed (as by use of a balloon catheter often followed by placement of a stent) or removed (as by atherectomy)...

Aspirin (17) and ticlopidine 18, 19, used to prevent stent thrombosis, are known to increase the risk of bleeding when administered before a surgical procedure. Some of the patients had no discontinuation of either medication after stent placement, placing them at an even higher risk for ...
Changes in coronary bifurcations after stent placement in the main vessel and balloon opening of stent cells: theory and practical veri- fication on a bench-test model. J Geriatr. Cardiol, 2008; 5: 43-49.Vassilev D, Gil RJ. Changes in coronary bifurcations after stent placement in the main...
Coronary intravascular stent placementis usually done during an angioplasty. A stent is a hollow tube made of wire mesh that is put into a coronary artery. The stent supports the artery and keeps it open so blood can flow through it. ...
