Are there any alternate options to heart valve surgery?

Not good ones: No one is forced to have heart valve surgery. If your valve is functioning so poorly that repair or replacement has been recommended, you can opt to have comfort measures indefinitely until you pass on.

Yes: There are options but depending on the situation they may not be very good. It depends on the valve involved, the type of pathology, how ill the patient is and the symptoms being experienced. Medical management is almost always done for a time (days to months) and can be appropriate for many patients. There are also less invasive approaches.
