If your mitral valve
stenosis is mild or moderate, you should be able to have a safe pregnancy using
a combination of
diuretics and beta-blockers, medicines that can reduce
stress on the heart.
But if your mitral
valve stenosis is severe or causes symptoms, you may need surgery
before you conceive. In this case, you may need balloon
valvotomy, which temporarily repairs the valve by inflating a balloon inside it
to widen the valve opening. This works only if your valve leaflets are pliable
enough and are not overly scarred.
Mitral valve replacement is not a good option for women who want to become
pregnant, because this surgery requires taking
anticoagulants after the valve replacement. Some
anticoagulants are dangerous during pregnancy.

pregnant and develop severe symptoms of mitral valve stenosis, your doctor may
