Why is the doctor performing this surgery?
|To replace a poorly functioning heart valve. The valve can
be narrowed and obstruct blood flow (called Stenosis), or it can be
floppy/leaky (called Insufficiency). Properly functioning heart valves are
essential to direct the flow of blood thru the heart, and to maintain a
normal workload for the heart. The most common heart valves surgically
replaced are the mitral valve and the aortic valve.

What is the surgery?
This surgery is an open-heart procedure to remove the poorly functioning
(either Stenotic or Insufficient) valve, and replace it with either a mechanical
(synthetic/man-made) or a tissue (biologic/from another organism) valve. The
pumping and oxygenation function of the heart is taken over by a heart-lung
machine during the surgery, and medications are given that briefly paralyze the
heart (Cardioplegia). This way, the heart is completely at rest while the
surgeon performs the replacement surgery.
Please note: Patients receiving a mechanical valve replacement will be
required to take a blood-thinning medication called Coumadin (an anticoagulant)
daily for life to prevent blood clots from forming on the prosthetic valve.
Where is the surgery performed?
In the Operating Room (OR), under general anesthesia.
How long does this surgery take?
The surgery length of time will vary based on which valve is replaced, the
type of replacement valve, the patient's underlying medical condition, etc, but
a good estimate for Valve Replacement Surgery is 3 - 6 hours.
