WHAT YOU SHOULD
KNOW
Right heart catheterization (KATH-uh-TER-i-ZA-shun) is a
test that permits your doctor to inspect the inside of your
heart's right chambers, where blood returning from the body is
pumped into the lungs for a fresh supply of oxygen. The
procedure is also called a "right heart cath."
In this test, the tip of a catheter (a long, thin,
bendable tube) is inserted into a vein under your collarbone,
in your neck, or in your arm or groin (the area between your
abdomen and the top of your leg). Using a TV screen and x-rays,
the physician then threads the catheter along the vein, through
the heart, and into the blood vessels going to your
lungs.
During the procedure, doctors can check blood pressure in
the chambers of the heart, measure the oxygen level of the
blood in different parts of your heart, and examine the valves
between the chambers of your heart.
The test takes about 1 to 2 hours. You may go home
afterwards or stay in the hospital
overnight.
Risks
Although the test rarely causes a problem, there are
risks to consider. For example, the catheter could make a hole
in a blood vessel, and you might need immediate surgery to
repair it. The catheter could disrupt your heartbeat or cause a
heart attack. Fluid could build up in your lungs and make
breathing difficult. A blood clot could travel to your brain
and cause a stroke, or lodge in a lung and disable it, or
settle in an arm or leg and prevent the blood from reaching it.
Your kidneys could also be affected. Doctors watch closely for
any sign of a developing problem.
On the other hand, if you don't have the test, a serious
heart condition may go undetected, leaving you in danger of a
heart attack.
IF YOU'RE HEADING FOR THE
HOSPITAL...
Before You
Go
-
The Week Before Your Right Heart
Cath:
-
You should stop taking
aspirin or ibuprofen a few days before the test; your
doctor will tell you when. If you've been told to take
aspirin daily, do not stop without asking
first.
-
If you are taking a blood
thinner, you may need to stop 2 or 3 days before the test.
Check with your doctor, however, before you stop taking
this or any medicine.
-
Consult your doctor before
taking any over-the-counter medicine.
-
A dye will be used during the
test to show up the parts of your heart better. People who
are allergic to shellfish (lobster, crab, or shrimp) may
also be allergic to this dye. If you have such an allergy,
make sure the doctor is aware of it.
-
You may need to make an
appointment to have blood drawn for lab
tests.
-
The Night Before Your Right Heart
Cath:
-
You may be given a pill to
take to help you sleep.
-
You'll need to stop eating
and drinking anything (even water). The doctor will tell
you when.
When You
Arrive
-
Before taking any medicine on
the day of the procedure, check with your doctor. These
medicines include insulin, diabetic pills, high blood
pressure pills, or heart pills. Bring a list of your
medicines, or the pill bottles themselves, with you to the
hospital.
-
Do not wear contact lenses
the day of your heart cath. You may wear
glasses.
-
An anesthesiologist may talk
to you before the test begins. This is the doctor who will
give you medicine to make you sleepy during the
procedure.
What to Expect While You're
There
You may encounter the following procedures and equipment
during your stay.
-
Taking Vital Signs: These include your temperature,
blood pressure, pulse (counting your heartbeats), and
respirations (counting your breaths). A stethoscope is used
to listen to your heart and lungs. Your blood pressure is
taken by wrapping a cuff around your
arm.
-
Dye: You will be given dye through an IV tube to
make your heart and arteries show up better on x-rays. As
the dye is put into the IV, you may have a reaction. You
may feel warm all over, or just in your head. You may get a
headache or feel sick to your stomach. Your heart may seem
to skip beats or have extra ones. These are normal symptoms
that quickly disappear. However, if you feel chest pain or
angina while you are getting the dye, let your doctor know
immediately.
-
Blood Tests: You may need blood taken for tests. It
can be drawn from a vein in your hand or from the bend in
your elbow. Several samples may be
needed.
-
Chest X-ray: This is a picture of your lungs and
heart that will help the doctor during the
procedure.
-
Heart Monitor: (Also called an electrocardiogram
[e-LEK-tro-KAR-di-o-gram] or EKG). Three to five sticky
pads are placed on different parts of your body. Each pad
has a wire that is hooked to a TV-type screen or to a small
portable box (telemetry unit) that shows a tracing of each
heartbeat. Your heartbeat will be carefully monitored
throughout the procedure.
-
IV: A tube placed in your vein for giving medicine
or liquids. It will be capped or have tubing connected to
it.
-
Oxygen: Your body may need extra oxygen at this
time. It is given either through a plastic mask over your
mouth and nose or through nasal prongs. Tell your doctor if
the oxygen is drying out your nose, or if the nasal prongs
bother you. Don't take off your oxygen without asking your
doctor or nurse. If you do, your body may not get enough
oxygen.
-
Pulse Oximeter: To check the amount of oxygen in
your blood, you may be hooked up to a pulse oximeter
(ox-IM-uh-ter). It is placed on your ear, finger, or toe
and connected to a machine that reads the
level.
-
Blood Pressure: A doctor may take a blood pressure
reading in both arms and both legs.
-
Pulse: The pulse (heartbeats) in your feet and
ankles will be measured. The pulse is the beat you feel
under the skin when the heart pushes blood through a vein
or artery. A doctor may put an "X" over the spots on your
legs and feet where the pulse is the
strongest.
-
Anesthesia: Right before the procedure, you may be
given medicine to make you feel sleepy and more relaxed and
to dull pain from the procedure.
When the Procedure Is
Over
The catheter will be removed and a tight pressure bandage
will be put over the entry point. Nurses will use a sandbag to
keep pressure on the bandage and stop any bleeding. The sandbag
needs to stay in place for 2 hours or more. Don't get out of
bed until your doctor says it's OK.
-
Activity: You will need to lie flat and still in bed
for at least 4 hours after the procedure (the doctor will
tell you when it's OK to get up). If you get tired of lying
on your back, let the nurses know. They can help you
"log-roll" from side to side. Staying in bed is especially
important if the catheter was inserted in your leg because
you must keep the leg straight for at least 4 hours after
the heart cath. Call for your doctor before getting up for
the first time. If you ever feel weak or dizzy, sit or lie
down right away and call a nurse.
-
Eating: Shortly after the procedure, you may be able
to eat "finger foods" while lying flat in
bed.
-
Pain Medicine: You'll probably be given medicine to
ease your pain. This medicine may be given in your IV, as a
shot, or by mouth. Tell the nurse if the pain does not go
away or comes back.
-
Pressure Stockings: These tight elastic stockings
keep blood from pooling in the legs and causing
clots.
-
Pneumatic Boots: These are plastic boots or leggings
put on over pressure stockings or ace wraps and connected
to an air pump machine. The pump tightens and loosens
different parts of the boot to help push the blood back up
to the heart and keep clots from
forming.
-
Tell Your Doctor If:
-
You have chest
pain.
-
The leg or arm where the
catheter was inserted feels hot, cold, tingly, or numb, or
turns a different color.
-
The area where the catheter
was inserted is swollen or bleeding.
-
You have pain in your back,
thigh or groin.
-
You feel nauseated or start
to sweat a lot.
After You
Leave:
-
You must take it easy for the
rest of the day on which you have your heart cath. Rest or
lie down on a couch. Do not walk except to go to the
bathroom. You may start your normal activities on the
following day.
-
Take a sponge bath when you
get home to keep the area around the point of entry clean.
Keep the bandage clean and dry until the following morning.
Then you may take it off and bathe or shower
normally.
-
If the place where the
catheter was inserted starts to bleed, put pressure on the
bandage with your hand. Hold this pressure for 30 minutes.
Call your doctor to report the bleeding. If it doesn't
stop,
call 911 or 0 (operator) to get transportation to
the nearest hospital or clinic.
This is an emergency. Do not drive
yourself!
-
Watch the place where the
catheter was inserted. It is normal to have a bruise. Draw
a line with a pen around the edges of the bruise so you can
see whether it is starting to get
bigger.
-
Always take your medicine as
directed. If you feel it is not helping, call your doctor,
but do not quit taking it without his
OK.
-
Continue to take the
medicines you were taking before the heart cath. If you
were taking a blood thinner, such as Coumadin, ask your
doctor when you should start taking it again. You may have
to have your blood checked if you are taking this type of
medication.
-
Do
NOT take any medicine that contains aspirin or
ibuprofen Ask your doctor before taking
any over-the-counter
medications.
-
If your doctor has prescribed
antibiotics, continue to take them until they are all
gone---even if you feel better.
-
Do not lift anything heavier
than 20 pounds for 2 days.
-
You may eat your regular diet
as soon as you get home. Since you will have to lie down
and rest on the first day, eat foods that you can swallow
easily. Starting on the second day, resume a regular
balanced diet. Healthy eating can boost your energy and
speed the healing process.
-
You may be told to eat foods
that are low in fat. You may also be told to limit the
amount of salt you eat. This means not adding salt to your
food during meals or when you cook. If you need help with
your diet, ask your doctor for
suggestions.
-
Drink 6 to 8 large glasses of
liquid each day. (Or follow your doctor's advice if you are
on a fluid limit.) Good liquids to drink are water, juices,
and milk. Limit the amount of caffeine you drink by cutting
down on or eliminating caffeinated coffee, tea, and
soda.
-
Your doctor will tell you
when you can start driving again.
Call Your Doctor
If:
-
You have nausea or vomiting
for several hours.
Seek Care Immediately
If:
-
Nausea or vomiting
continues.
-
The vein used for the heart
cath begins bleeding and won't stop.
-
The bruise where the catheter
was inserted gets bigger and becomes
swollen.
-
The leg or arm used for the
heart cath becomes numb or painful, or changes
color.
