Mitral valve stenosis is a concern if
you are pregnant or are thinking of becoming pregnant. It is associated with
increased risks to you and the fetus (baby), particularly if your condition is
severe and you have
heart failure.
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.1
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.1
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.
If you are already
pregnant and develop severe symptoms of mitral valve stenosis, your doctor may
recommend balloon valvotomy. Balloon valvotomy can be performed safely during
pregnancy, with little risk to mother or baby.1 But
surgery during pregnancy should be considered only after your doctor has tried
other treatments, such as medicines.
Pregnant women with mitral
valve stenosis are best cared for by a team that includes a cardiologist and an
obstetrician.
