What is Mitral Valve? The left atrio-ventricular dual flap valve lying
between left ventricle and left atrium of heart is termed as Mitral Valve
or Bicuspid valve.
What is Mitral valve Regurgitation (MR)?
Mitral Valve Regurgitation is a problem that occurs due to mitral valve
prolapse. Mitral valve prolapse means that the two tissue flaps and mitral
valve leaflets do not close properly. Since the mitral valve leaflets
are not closed and sealed tightly, the blood leaks in the wrong direction.
Mitral Valve Regurgitation Surgery
When the regurgitation is acute i.e. severe, it leads to Mitral Valve
Disorder (also called as Mitral insufficiency or Mitral incompetence).
Patient suffering from Mitral Valve Disorder has to undergo Mitral Valve
Regurgitation Surgery to make the ventricles work properly. If not, the
cardiac muscle might get damaged.
has to undergo this surgery even if he has trouble in breathing or suffers
from heart failure. If the patient has swelling or fatigue, then he has
to be checked for the regurgitation severity which might be measured using
MRI, Echo Cardiogram, Cardiac Catheterization or Stress Echo.
If regurgitation severity is high, then the patient has to undergo Mitral
Valve Regurgitation Surgery. If the ejection fraction is less than 60%
or if the left ventricle is more than 40mm while at rest, then again this
surgery has to be undertaken.
Valve Regurgitation Surgery Procedure
During Mitral Valve Regurgitation Surgery, the affected valve will either
be repaired or replaced. Based on the type of damage, appropriate surgery
procedure will be chosen.
Regurgitation Surgery - Repairing the Mitral Valve
As part of Mitral Valve Regurgitation Surgery, the mitral valve can be
repaired in one of the following ways: (1) Valve can be reshaped to close
tightly (2) Excess Tissue can be removed from the valve (3) Valve Ring
can be supported by using proper methodologies (4) Chordal transposition
can be done so that the valve gets attached to chord like tissues located
in the heart.
the mitral valve through Mitral Valve Regurgitation Surgery, the patient
gains the following benefits: Long time survival assurance, improvement
in the functioning of left ventricle, low risk of bleeding and considerably
short time need of anticoagulants.
Regurgitation Surgery - Replacing the Mitral Valve
The first step in replacing mitral valve is deciding which type of valve
has to be used mechanical valve or bio-prosthetic valve. After
deciding the type of valve, the damaged mitral valve is removed and replaced
with the selected valve. Note that if mechanical valve is placed, life
time consumption of an anticoagulant medicine is a must to avoid blood
clot in the blood.
