I was told very little else about possible risks of a heart murmur and pregnancy. I have hardly noticed my murmur over the years, but over the last week and a half, every time I lie down to go to sleep, I have heart palpitations for up to 10 minutes. She has assisted at over 1,000 births and is currently teaching in the nurse-midwifery program at the University of Minnesota. Heart murmurs are very common in pregnancy, due to changes brought on by hormones and by the increase in blood volume.
Most pregnant women have a systolic end murmur.
Yours, however, because it is due to mitral valve prolapse, needs more consideration than the typical murmur of pregnancy. Mitral valve prolapse is the most common congenital heart condition found in women of childbearing age. There appears to be a genetic predisposition to this condition. Most women with MVP have no symptoms, while some experience palpitations. The need for antibiotics is still debated.
