Abstract
Color Doppler echocardiography of the left mammary artery was combined with dipyridamole testing in order to assess the presence of signific ant (>70%) graft stenosis in 87 patients with a mammary artery graft t o the left anterior descending coronary artery presenting with chest p ain. Occluded grafts are detected by absent diastolic flow velocities at baseline, whereas the response of the diastolic flow velocity to di pyridamole distinguishes patients with critical versus noncritical ste nosis of a patent graft.
