An enlarged heart (cardiomegaly) may have various causes. But it's usually the result of high blood pressure (hypertension) or coronary artery disease.
An enlarged heart may not pump blood effectively, resulting in congestive heart failure. Cardiomegaly may improve over time. But most people with an enlarged heart need lifelong treatment with medications.
Valve replacement may be recommended if your mitral valve is seriously damaged and cannot be repaired.
The decision about whether to repair or replace a
valve is based on many things, including your general health, the
condition of the damaged valve, the presence of other health conditions, and
the expected benefits of surgery. In some cases, the decision clearly may be in
favor of repair or in favor of replacement.
Repair is more successful if there is not a lot of
damage to certain areas of the mitral valve flaps (leaflets) or to the tough
fibers that control movement of the mitral valve leaflets (chordae tendineae).
Mitral valve repair is usually preferred if your valve is suitable
for reconstruction and the surgeon has the appropriate level of experience and
The advantages of mitral valve repair include the

It may lead to fewer complications and better results
after surgery than with mitral valve replacement.
When is valve replacement recommended?
Examples of serious damage or complicated conditions that might
lead to mitral valve replacement include:
Extensive ballooning of the mitral valve
(rather than a single flap that puffs up).
(calcification) of the valve.
Prolapse (bulging) of the valve at an
