What are the indications for reoperative CABG?
Reoperative CABG is indicated in patients with a patent LIMA to the LAD artery and ischemia in the distribution of the right or left circumflex coronary arteries if GDMT has failed and the coronary stenoses are not amenable to PCI. Additionally, a stenosis of a graft to the LAD artery that is greater than 50% is an indication for reoperation. Patients without ischemia in the LAD artery distribution do not derive a survival benefit from repeat CABG.
