Abstract

Digital angiography has been reported to be a valid technique for anatomical studies of the peripheral cardiovascular system and for dynamic studies of ventricular function. The purpose of the present study was to assess the usefulness and accuracy of venous digital angiography (2 images per second) for imaging coronary bypass grafts after coronary artery bypass surgery, comparing its results with those of selective angiography. Fifty-two patients with 108 grafts (101 venous grafts and 7 internal mammary artery grafts) were studied by venous digital angiography and selective angiography. Venous digital angiography correctly diagnosed 95 out of 97 patent grafts and the 11 occluded grafts visualized by selective angiography. These results are better than those obtained in the very few studies so far reported in the literature. We were not able to adequately visualize distal anastomoses in most patients although we could identify the distal portion of 7 out of 8 patent sequential bypass grafts. Thus, these results suggest that venous digital angiography is a useful and accurate technique for assessing coronary bypass graft patency. © 1986 The European Society of Cardiology.
