View larger version (44K): [in a new window]   Figure 4 Debris scores expressed as percent of total debris for each catheter type. AL = Amplatz left; AR = Amplatz right; HS = hockey stick; JL = Judkins left; JR = Judkins right; LIMA = left internal mammary artery; Multi = multipurpose; VL = voda left; *p value <0.05 relative to any catheter; thus, JR catheters scrape less debris, and Multi and JL catheters scrape significantly more debris than does the average guiding catheter. Debris score: open columns = 1+; striped columns = 2+; solid columns = 3+.
