Key result
In symptomatic patients undergoing repeat angiography, internal thoracic artery grafts had a significantly lower occlusion rate compared to saphenous vein grafts (7.0% vs 16.5%, P<0.001).
Why the study?
Do internal thoracic artery grafts have superior angiographic patency compared to saphenous vein grafts in symptomatic patients after CABG?
Population
1,189 symptomatic patients who underwent CABG and subsequent angiography due to reappearance of angina
Comparison
Internal thoracic artery grafts vs Saphenous vein grafts (SVG)
Design
Cohort
Follow-up
3.8 +/- 2.7 years

ITA occlusion lower than SVG in symptomatic patients; extends observational data but leaves generalizability open.

Do internal thoracic artery grafts have superior angiographic patency compared to saphenous vein grafts in symptomatic patients after CABG?
Absolute Event Rate: 7% vs 16.5%
p-value: p=<0.001
Internal thoracic artery grafts demonstrate superior angiographic patency compared to saphenous vein grafts, even in a negatively selected population presenting with recurrent angina.
Gansera et al. (2007) conducted an observational in Reappearance of angina after CABG (n=1,189). Internal Thoracic Artery (ITA) grafts vs. Saphenous Vein Grafts (SVG) was evaluated on Graft occlusion rate (p=<0.001). In symptomatic patients undergoing repeat angiography, internal thoracic artery grafts had a significantly lower occlusion rate compared to saphenous vein grafts (7.0% vs 16.5%, P<0.001).
