What are 5 heart bypasses called?

Coronary artery bypass graft (CABG), also known as quintuple bypass surgery, involves grafting healthy blood vessels from other parts of the body to bypass blocked or narrowed coronary arteries. The number of bypasses performed depends on the extent and location of the blockages.

The five bypasses are typically:

1. Left anterior descending (LAD) bypass: This bypass grafts a blood vessel around the blockage in the LAD, which supplies blood to the front of the heart.

2. Right coronary artery (RCA) bypass: This bypass grafts a blood vessel around the blockage in the RCA, which supplies blood to the right side of the heart.

3. Left circumflex artery (LCx) bypass: This bypass grafts a blood vessel around the blockage in the LCx, which supplies blood to the left side of the heart.

4. Diagonal branch bypass: This bypass grafts a blood vessel around the blockage in the diagonal branch, which is a branch of the LAD that supplies blood to the front of the heart.

5. Posterior descending artery (PDA) bypass: This bypass grafts a blood vessel around the blockage in the PDA, which is a branch of the RCA that supplies blood to the back of the heart.

The number of bypasses required is determined by the surgeon based on the patient's individual anatomy and the extent of the coronary artery disease.
