Coronary angiography
Prior to coronary artery bypass grafting
It is often recommended that the first view that is performed on diagnostic coronary angiography is the RAO caudal so that any stenoses in the circumflex and the left anterior descending as well as the distal targets can be assessed in case the patient becomes critically ill following the initial injection in the left main. If the patient is not critically ill, then angiography should be performed in an adequate number of views to identify all blockages that should be bypassed as well as the size, calcification and disease extent of target vessels. Angiography should continue for a sufficient duration of time so as to evaluate the presence and quality of distal vessels that are collateralized that my need to be bypassed. Although left ventriculography is helpful in the assessment of left ventricular function, this can also be assessed on echocardiography to minimize the dye load and the potential for hemodynamic collapse with excess contrast agent.
Following coronary artery bypass grafting
Use of radio-opaque saphenous vein graft markers has been associated with the following in non-randomized observational studies:
- Reduced volume of contrast injections
- Shorter cardiac catheterization procedure times
- Greater rates of identification of occluded SVGs (90.7% vs 72.1%, p < 0.001)[1]
- No increase in the risk of SVG failure [1]
- An unexplained increase in the risk of perioperative MI in non-randomized analyses [1]
- No increase in the risk of death or MI by 12-18 months of follow-up.
