Key words: angioplasty, brachytherapy, laser, restenosis Trials comparing coronary artery stenting to coronary artery bypass grafting (CABG) have shown that repeat revascularization continues to be the main limitation of percutaneous...

The initial evaluation of radiotherapy in animal models of restenosis focused on the used of 192Iridium ribbons, a commercially available source. After initial animal studies revealed that therapy with this isotope reliably inhibited vascular...

Diffuse, in-stent restenosis, characterized by lesions greater than 10 mm in length, is associated with revascularization rates ranging from 34% to more than 80% following conventional percutaneous coronary intervention (PCI).1 Lesion lengths...

Although catheter-based brachytherapy has been demonstrated to effectively treat in-stent restenosis, a technique-dependent issue known as “geographic miss” has evolved as a potential limitation contributing to long-term treatment failures....

Treatment of bifurcation lesions has been associated with lower success and higher complications rates. They represent a major interventional challenge. Redistribution of plaque (snowplow effect) often leads to occlusion of the side branch....
