Presentation Transcript

  1. RAPS Radial Artery and Saphenous Vein Patency More Than 5 Years Following CABG Surgery: Results from the Randomized Multicenter Radial Artery Patency Study Objective • To compare the angiographic patency of radial-artery grafts with that of saphenous-vein grafts (SVGs) 8 to 12 months post surgery Study Design • Randomized, Multicenter • Within patient randomization of grafts (each patient had both a radial artery graft and a SVG) • 561 patients, 440 with angiographic follow-up Primary Endpoint • Total occlusion at 1 year

  2. RAPS 1-Year Results p=0.009 p<0.001 p=0.003 p=0.001 • No significant differences at distal anastomosis or in perfect graft patency

  3. RAPS 5-Year Results p=0.05 p=0.004 p=0.02 Conclusion • Overall the study showed reduced rates of both functional and total graft occlusion as well as less graft disease with radial artery grafting compared with SVG
