A stent is an extendable metal scaffold that can be used to keep open previously narrowed coronary arteries after angioplasty has been performed. The mechanism used to place the stent in a narrowed or blocked coronary artery is very similar to balloon angioplasty. The difference is that the un-...
Coronary angioplasty (PTCA): This procedure is similar to coronary angiography (cardiac catheterization or a dye study to visualize the inside of coronary arteries) but is therapeutic as well as diagnostic. A similar but sturdier tube (guide catheter) is inserted into an artery in your groin or ...
In 1994, two major randomized trials confirmed that stenting after percutaneous transluminal coronary angioplasty (PTCA) does indeed reduce the incidence of restenosis, as well as other events like myocardial infarctions and emergency surgery. Numerous stents are now in use: self-expanding and balloon...
Complete or incomplete percutaneous coronary revascularization in patients with unstable angina in stent era: Are early and one-year results different? The aim of our study was to evaluate the impact of a strategy of incomplete revascularization by PTCA, with or without stent implantation, on clinica...

This study reports the first multicenter experience with the Wiktor coil stent for treatment of chronic total coronary artery occlusions (CTOs). Background. Percutaneous transluminal coronary angioplasty (PTCA) of CTO is associated with very high restenosis and reocclusion rates. Coronary stenting has ...
