Cardiac
catheterization is a minimally invasive procedure in which
a long, thin tube called a catheter is guided into the heart,
usually through a blood vessel in the leg or arm. Once inside
the heart, it can be used to diagnose a problem or to treat
a problem.
By gaining access to the beating heart, cardiac catheters
allow a physician to check the internal blood pressure of the
heart, assess blood supply, view the coronary arteries on the
surface of the heart and (depending on whether another test
is done) the aorta, and check the level of oxygen in the blood.
It is also used to evaluate the ability of the pumping chambers
to contract, as well as to assess valvular function. Cardiac
catheterization is one of the most accurate tests in the diagnosis
of coronary artery disease, and over a million of them are
done each year.
During cardiac catheterization, the catheter is inserted through
a very small cut made by the physician (in the groin, arm or
wrist), then guided up through the blood vessel to the heart.
The physician tracks the course of the catheter by watching
it on a fluoroscope, an x-ray machine that displays the catheter
and blood vessels in real time on a screen. A variety of measurements
may be performed when the catheter is in place, and then the
catheter is removed. After about 6 hours of recovery time,
most patients are free to go home. Results are often available
within a matter of hours.
Titus Regional Medical Center offers a patient-friendly environment
designed for care and comfort during cardiac catheterizations. For more information or to see if a cardiac catheterization may be right for you, please check with your primary care physician.
