To assess the likelihood of procedural success in patients with multivessel coronary disease undergoing percutaneous coronary angioplasty, 350 for type C stenoses, a 61% success and a 21% complication rate. The subdivision into types Bi and B2 provided significantly more information in this clinically importantintermediate risk group than did the standard ACC/AHA scheme. The stenosis characteristics of chronic total occlusion, highgrade (80-99% diameter) stenosis, stenosis bend of more than 60°, and excessive tortuosity were particularly predictive of adverse procedural outcome. This improved scheme may improve clinical decision making and provide a framework on which to base meaningful subgroup analysis in randomized trials assessing the efficacy of percutaneous coronary angioplasty.

Coronary revascularization may be an effective palliative therapy in suitable cardiac transplant recipients. Angioplasty has an acceptable survival in patients without angiographic distal arteriopathy. Because few patients underwent atherectomy and coronary bypass surgery, assessment of these procedures is limited. Angiographic distal arteriopathy is associated with decreased allograft survival in patients requiring revascularization.

In this collaborative meta-analysis, the level of on-treatment platelet reactivity according to the P2Y(12) assay is associated with long-term cardiovascular events after percutaneous coronary intervention, including death, MI, and stent thrombosis.
