摘要: Abstract Background . The flow capacity of the right gastroepiploic artery graft has not been clarified. Methods Angiographic and echocardiographic studies were conducted in 30 patients who had undergone coronary bypass grafting using both internal thoracic arteries. luminal diameter arterial grafts was measured from postoperative angiograms. adequacy myocardial blood supply evaluated by dobutamine stress echocardiography. Results With echocardiography, 14 exhibited an ischemic response grafted region, whereas no area. a younger age correlated with observed A greater than 2.6 mm highest sensitivity specificity for nonischemic change. Conclusions To generate maximal reserve, when used as should be sufficiently large enough, nearly 3 at anastomosis.
