Primary Stenting Versus Balloon Angioplasty in Occluded Coronary Arteries
Background—Balloon angioplasty (PTCA) of occluded coronary arteries is limited by high rates of restenosis and reocclusion. Although stenting improves results in anatomically simple occlusions, its effect on patency and clinical outcome in a broadly selected population with occluded coronary arteries is unknown. Methods and Results—Eighteen centers randomized 410 patients with nonacute native c...
متن کاملRandomised trial of elective stenting after successful percutaneous transluminal coronary angioplasty of occluded coronary arteries.
BACKGROUND The value of angioplasty in occluded coronary arteries is limited by a restenosis/reocclusion rate of 50-70%. In patients with subtotal occlusion, stent implantation has been shown to reduce clinical and angiographic restenosis. Retrospective observational studies have suggested that stenting could reduce restenosis in total occlusions. The value of sustained coronary patency on glob...
متن کاملCoronary Stenting
Stents are metallic scaffolds that are deployed within a diseased segment of coronary artery to establish and then maintain a widely patent lumen. Just 6 years after the 1994 approval of the balloon-expandable Palmaz-Schatz slotted tube stent in the United States, stents are utilized in upwards of 80% of interventions and have revolutionized catheter-based treatment. Given the rapid evolution i...

متن کاملRandomized comparison of coronary stenting with optimal balloon angioplasty for treatment of lesions in small coronary arteries.
AIMS Angioplasty of lesions in small coronary arteries remains a significant problem because of the increased risk of restenosis. The aim of this study was to compare the efficacy of elective coronary stent placement and optimal balloon angioplasty in small vessel disease. METHODS One hundred and twenty patients with lesions in small coronary arteries (de novo, non-ostial lesion and reference...
