Summary

The use of a graft from the left internal thoracic artery to the left anterior descending artery has become the gold standard for the indication of coronary artery bypass grafting. However, choosing a graft for the second-best coronary artery, focusing on long-term patency, is still a challenge. The saphenous vein using the "no-touch" technique is an alternative to a radial artery graft, but there is little evidence, especially in women. This randomized clinical study aims to compare the patency of these grafts in the second-best coronary artery in women undergoing coronary artery bypass grafting.

Conditions

  • Cardiac Disease
  • Surgery-Complications
  • Graft Failure

Interventions

PROCEDURE

Coronary artery bypass graft

Randomization will be performed for stratification according to the target coronary arteries and the randomly determined block size from 4 to 6. The randomization result will be delivered in a sealed envelope in the operating room (before the time out) for one of the two drawn strategies.
