CORONARY ARTERY BYPASS GRAFT
SURGERY

Coronary artery bypass grafting (CABG) is the most common open heart surgery. If
you have been diagnosed with coronary artery disease (CAD) or clogged heart arteries,
this surgery will improve blood flow
to your heart. There are many
arteries suppling blood to your
heart. Your surgeon sees which of
these arteries are not able to supply
good blood flow to the heart muscle
by looking at the pictures from your
cardiac catheterization. This will
determine the number of areas that
need to be treated. It is possible to
need a single bypass (1 diseased
artery), double bypass (2), triple
bypass (3) or a quadruple (4)
bypass.

A CABG treats the clogged arteries by bypassing the blocked portion of the coronary
artery with a healthy blood vessel from somewhere else in the body. This provides a
clean route for blood to flow so the heart muscle can get enough oxygen filled blood.
