1 Angiographic predictors of 3-year patency of bypass grafts implanted on the right coronary artery system: A prospective randomized comparison of gastroepiploic artery, saphenous vein, and right internal thoracic artery grafts  David Glineur, MD, PhD, William D’hoore, MD, PhD, Laurent de Kerchove, MD, Philippe Noirhomme, MD, Joel Price, MD, MPH, Claude Hanet, MD, PhD, Gebrine El Khoury, MD  The Journal of Thoracic and Cardiovascular Surgery  Volume 142, Issue 5, Pages (November 2011) DOI: /j.jtcvs Copyright © 2011 The American Association for Thoracic Surgery Terms and Conditions

2 Figure 1 Flow chart of the study. CABG, Coronary artery bypass grafting; RGEA, right gastroepiploic artery; SVG, saphenous vein graft; BITA, bilateral internal thoracic artery.

3 Figure 2 Relationship (least-squares regression line [RITA, continuous line; RGEA, interrupted line; SVG, dotted line]) among patency scores of SVG (square dot), RGEA (triangle dot), and RITA (round dot) and MLD of the grafted RCA. MLD, Minimum lumen diameter; RCA, right coronary artery; RGEA, right gastroepiploic artery; RITA, right internal thoracic artery; SVG, saphenous vein graft.

4 Figure 3 Relationship between patency scores of the analyzed grafts (SVG, RGEA, RITA) and MLD (left) and percent stenosis (right) of the grafted RCA. The box ends are Tukey’s hinges; the whiskers are at the largest and smallest values that are not outliers or extremes, which are defined as 1.5 and 3.0 interquartile ranges from the hinges. MLD, Minimum lumen diameter; RGEA, right gastroepiploic artery; RITA, right internal thoracic artery; SVG, saphenous vein graft.
