text: i have a very slight regurge in my lower tricuspid valve. will mirena make it worse? the mirena pamplet i have lists that people with valve trouble should not use mirena. i only have a slight regurge in one of my heart valves, i don't even see a heart doctor as it was not recommended by my family doc.  i am 32 years old... should i worry about the effects of mirena?  i don't want the surgery of a tubal and taking birth control made me moody and gain 20 pounds! if you are concerned with this, and your family doc cannot answer your question, perhaps it is time to see that heart specialist.
