Causes Of Bicornuate Uterus: A bicornuate uterus is a congenital abnormality, which means it’s something a woman is born with. It happens when a baby girl’s uterus doesn’t develop normally in the womb. Special ducts only partially fuse together, which leads to separation of the two upper parts, or horns, of the uterus. When the horns stick out a little, the womb appears to be heart-shaped. You can’t prevent or stop this condition if you have it. Diagnosis Doctors can use the following tests to diagnose a bicornuate uterus: ultrasound magnetic resonance imaging (MRI) hysterosalpingogram pelvic exam Most often, the condition is detected during an ultrasound that’s performed to look at your uterus during pregnancy or when you’re experiencing unwanted symptoms. Many women are surprised to find out they have a heart-shaped uterus. Some will go their whole lives without knowing they have the condition. Treatment Surgery, called a Strassman metroplasty, can sometimes be used to correct a bicornuate uterus in women with a history of miscarriage. In one analysisTrusted Source, 88 percent of those who had a Strassman metroplasty achieved pregnancies that ended with a successful birth. However, the majority of women won’t need surgery to repair a bicornuate uterus. Performing this procedure in women with a bicornuate uterus who experience infertility is controversial in the medical community. This is because most research suggests that the condition doesn’t affect a woman’s chances of becoming pregnant. Best Fertility Care Centre.
