Insights
Routine placement of aorto-coronary graft markers during coronary artery bypass (CAB) surgery significantly reduces fluoroscopy time, contrast volume, and catheter use in subsequent angiography, especially for patients with multiple grafts.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Medical Imaging
Background:
- Localizing the proximal aorto-coronary graft anastomosis during angiography can be challenging in patients with prior coronary artery bypass (CAB) surgery.
- This difficulty can complicate subsequent diagnostic and interventional procedures.
Purpose of the Study:
- To quantify the benefit of using aorto-coronary graft markers during CAB surgery.
- To assess the impact of these markers on subsequent angiography procedures.
Main Methods:
- Retrospective review of 414 angiograms from patients with prior CAB surgery.
- Comparison of cohorts with and without aorto-coronary graft markers.
Main Results:
- Significant reductions in fluoroscopy time (30.5%), contrast volume (21.7%), and angiographic catheters used (17.0%) were observed in patients with markers and two or more grafts.
- A trend towards reduced fluoroscopy time (23.8%) was noted for patients with a single marked graft.
Conclusions:
- Routine placement of aorto-coronary graft markers during CAB surgery is beneficial.
- The benefit is particularly pronounced when multiple grafts are placed, optimizing subsequent angiography.
Objective:
When coronary and graft angiography is required for patients with prior coronary artery bypass (CAB) graft surgery, it is often difficult to localize the proximal aorto-coronary graft anastamosis. Our goal was to quantify the potential benefit during subsequent angiography if the proximal anastamosis is marked by an aorto-coronary graft marker at the time of CAB.
Methods:
Retrospective review of 414 angiograms that were performed for patients with prior CAB. Cohorts with an without graft markers were compared.
Results:
In the group with aorto-coronary graft markers and > or = 2 aorto-coronary grafts, there were significant reductions in fluoroscopy time (30.5%, p < 0.0001), contrast volume (21.7%, p < 0.0001), and numbers of angiographic catheters used (17.0%, p = 0.0001). If only one aorto-coronary graft was placed and marked, a trend toward reduced fluoroscopy time was observed (23.8%, p = 0.07).
Conclusions:
This study demonstrates the objective benefit supporting routine placement of circumferential aorto-coronary graft markers during CAB, particularly if > 1 graft is required.
