Open-Heart Surgery - Beat by Beat
from Better Health magazine, Winter, 2003

From the moment of birth until death, a human
heart beats more than two and a half billion times
without even pausing to rest. Unfortunately, for
a variety of reasons, the vessels supplying blood
to the heart can become clogged. When that happens,
open-heart surgery may be the best answer.
What happens during open-heart surgery? What
heart problems require surgery vs. other types
of treatment for heart disease? We'll follow a
typical patient through diagnosis, treatment,
surgery, and recuperation to give you an inside
glimpse of the open-heart surgery which will be
done at Danville Regional Medican Center beginning
in late March.
The typical open-heart surgical patient comes
to us following a heart attack or when an examination
reveals extensive blockage of the coronary arteries,"
says Henry Tripp, Jr., M.D., Danville's new cardiovascular
surgeon. "Typically, the patient will have three
or more arteries significantly blocked in many
areas, a condition hard to repair with cardiac
catheterization alone."
About 85 percent of open-heart surgeries involve
blocked arteries; another 15 percent involve replacement
of heart valves which have been damaged by disease.
The bypass surgery procedure is called a Coronary
Arterial Bypass Graph, or CABG (often called "cabbage").
The operation replaces arteries on the front side
(anterior) and/or the back side (posterior) of
the heart, depending where the blockages have
occurred.
On the morning of the surgery, the patient is
given sedation before being placed under anesthesia.
Usually there are at least seven medical staff
in the operating room: the surgeon, a physician's
assistant who helps with suturing and preparing
the vessels, three nurses, an anesthesiologist,
and a perfusion technician who carefully monitors
the pressure and temperature of the blood traveling
through the heart-lung machine.
An incision is made through the breastbone,
and the ribcage is spread apart to reveal the
heart. One by one, the new vessels, usually mammary
arteries, are attached above and below the clogged
coronary arteries, bypassing the blockages and
rerouting the blood flow. In the typical CABG
procedure, between one and five vessels are replaced,
often referred to as "jumps."
The heart is stopped and the graphs are completed
while the pumping duties are taken over by the
external heart pump. Here blood is oxygenated
and kept at the correct temperature before being
returned to the body under controlled pressure.
Once the bypasses are complete, the heart is
once again started. The sutures are checked for
any minor leaks, then the ribcage and chest wall
are closed. "The procedure can take between three
and five hours, depending upon the complexity,"
says Dr. Tripp.
Once the surgery is complete, recuperation begins.
It is important for the patient to be as mobile
as possible to encourage good circulation and
to clear the lungs of any fluid. Respiratory therapy
and cardiac rehabilitation are important components
to a complete recovery.
Patients return home, usually within a week
following surgery. Counselors are available to
help the patient and family return to normal routines.
Exercise and proper nutrition are encouraged to
help keep the "new" heart in great condition for
years to come.
