Most of the time, pregnancy during mitral regurgitation (MR) can be
managed safely as long you receive careful medical attention. On rare
occasions, in order to make pregnancy safe, a woman may need to have valve
surgery before she becomes pregnant. Specifically, you should have valve
surgery before you conceive if you have ruptured chordae (chordae are
structures that anchor your mitral valve) or if your MR is severe.
If you are considering pregnancy and you have MR, you should gather
more advice from a multidisciplinary medical team who can provide more
information about your individual risk factors and long-term outcome.
