Before you have surgery to replace a heart valve due to a condition
such as
mitral valve stenosis or
mitral valve regurgitation, you will need to prepare
for your hospital stay.
Hospital preadmission
You will have to visit the hospital or your doctor's office several
days in advance of your surgery for a hospital preadmission session. During
this session, your medical team will educate you about your upcoming surgery.
They will also teach you how to prepare for your operation, explain what the
procedure will be like, and give you instructions for a successful recovery.
Some institutions even show a patient-education video about undergoing valve
replacement surgery.
You should use this time to ask questions. It is natural for you to
be anxious before your operation, so be sure to address issues that may be
causing you particular anxiety.
Informed consent
One of the issues that your doctor or nurse will discuss with you
during the preadmission session is informed consent. Your doctor or nurse will
describe the risks associated with a valve replacement surgery. These
include:
- Stroke.
- Bleeding.
- Infection.
-
Heart attack.
- Kidney failure.
- Death.
You will then be asked to sign a consent form (waiver) that you
should read carefully. Generally speaking, the consent form confirms that you
understand the risks associated with the procedure and relieves the hospital or
test center from any liability for complications that are not related to
negligence. You should feel free to ask questions about the form if there is
anything that you do not understand.
Preparatory procedures
During your preadmission session, you will undergo a range of
preparatory procedures. Your hospital staff will give you a few preliminary
tests, such as an
EKG and a blood test, to make sure that your bodily
functions are normal. You will also be asked to bathe or shower with an
antiseptic soap, while a technician will shave any hair from your chest and
abdomen, so that your body can be as clean as possible during surgery.
Anesthesia
One of the most important discussions you have prior to surgery
will be with your anesthesiologist, who will administer anesthesia during your
operation. Because general anesthesia carries significant risks, you will need
to describe your past medical history, including other operations you have had
and any allergies to food or medications. Mention any history, either personal
or within your family, of adverse reactions to anesthesia. Bring a list of
medications you are currently taking.
Before surgery
Because valve replacement surgery is a serious surgical procedure,
you should begin preparing for it several days ahead of time. Try to get into
good condition by eating healthfully, getting plenty of rest, and limiting
vigorous physical activity.
Beginning at midnight the night before your operation, do not eat
or drink anything (including water). Your doctor may also instruct you to take
a laxative to clean out your system. If you need to take medications, have them
with just a small amount of water.
During the operation
Before surgery begins, you will be put under general anesthesia,
which will be administered both through an IV line and through a mask placed
over your mouth and nose. When you are given general anesthesia, you will be
unconscious during the entire operation and will not feel anything.
While you are unconscious, your surgeon will make an incision along
the length of the breastbone and expose your heart. It will be hooked up to a
heart-lung machine. After blood flow is directed to this machine, the surgeon
will remove your damaged mitral valve and replace it with an artificial valve.
Most surgeries will take an average of 3 to 5 hours.
Immediately after the operation
When you first wake up after your operation, you will be in an
intensive care unit (ICU) so that your doctor can monitor your heart function
to make sure that there are no complications. You will also find many wires and
tubes inserted into different body parts. Most of these wires and tubes were
inserted while you were in surgery, but were kept to help your body perform
vital functions and to provide you intravenously with medication (primarily
painkillers) and nutrients. See the chart at the end of this section for
detailed information on these wires and tubes.
At first, you will feel drowsy and disoriented while the anesthesia
wears off. You may also experience some pain, though you will be given
painkillers. For the first few hours after surgery, you will be kept on a
respirator or ventilating machine to help you breathe.
The average length of stay in the ICU is 1 day, but your doctor may
keep you there longer if any complications develop.
Wires and tubes after heart valve
surgeryWire or tube | Where it attaches to
body | What it does |
|---|
| Heart monitor (EKG) wires | Chest, arm, and legs | Small, round sticky pads connected to an EKG
machine to monitor the electrical activity of your heart |
| Chest drainage tubes (usually 2) | Just below your surgical incision | Remove extra fluid, blood, and air that may
collect in your chest |
| Arterial line tube | In an artery | Used to continuously monitor your blood pressure
and to obtain blood samples. This tube can leave long-lasting bruising at the
insertion site. |
| IV lines | Generally in arms and neck | Provide nutrients and medications intravenously
(through your vein into your bloodstream) |
| Bladder catheter | In urethra | Drains urine |
| Temporary pacemaker wires | In chest | Used in case you need to be hooked up to a
pacemaker |
| Stomach drainage tube | Through mouth or nose | Drains waste that may be in your stomach. May be
used to give medications directly into the stomach |
| Breathing tube | In mouth | Helps you breathe and is left in until your doctor
is sure that you can breathe on your own. You will not be able to speak while
this tube is in your mouth. After this tube is removed, you will receive oxygen
through a mask or nasal prongs for a few days. |
Recovery after you leave the ICU
When your condition stabilizes and you have been moved to a regular
hospital room, you will continue to rest and recuperate while your doctor
monitors your recovery. Your care will also include physical and respiratory
therapy, emphasizing breathing exercises and simple exercise such as walking.
You will also receive counseling about a heart-healthy diet and exercises that
you should maintain after leaving the hospital.
The average length of stay in the hospital after valve replacement
is 7 to 12 days, though different hospitals have different policies in this
regard. Basically, before you are discharged and sent home, your doctor needs
to make sure that you are mending well and that there are no
complications.
