My heart murmur

  Hi, I'm sixteen, and in the future I was thinking about getting my tongue
  or labret pierced but I was told that since I have a heart murmur, getting
  anything in my mouth could lead to heart problems. I only have a slight heart
  murmur and have had only a slight one since birth...
  is this true ?
