Dear Lisa
Flow murmurs are common during pregnancy. If you recently had a normal echo, it is unlikely that you developed a problem with your heart so suddenly. If the murmur is in fact new and just a flow murmur, it should go away after pregnancy. A murmur with a normal heart is of little significance and should not pose a risk to surgery. If the murmur gets significantly louder, then the situation will need to be reevaluated. Also, it is possible that it is just a soft murmur that your other doctor did not hear or did not feel was worth commenting about.
I hope this has been useful. I wish you the best of luck. Feel free to write back.
