Summary

Bypass surgery is often required to treat severe coronary heart disease. Either arteries or veins can be used as bypass grafts. We wish to compare the long-term durability of the saphenous vein from the leg to that of the radial artery from the fore-arm when used as bypass grafts. We are examining how many of these grafts are still functioning beyond 5 years after bypass surgery by performing a coronary angiogram. After 1-year, we found that radial arteries were more likely to be functioning than saphenous veins. We hypothesize that radial arteries will continue to be superior beyond 5 years.

Conditions

Interventions

PROCEDURE

Radial Artery and Saphenous Vein Grafts Randomized to either right coronary or left circumflex coronary artery territories

Each patient will receive both study grafts (Radial artery and Study Saphenous vein graft). The within-patient randomization scheme will dictate whether the radial goes to the right or circumflex territory. The saphenous vein graft will go to the opposing territory.
