A finding to suggest a bicornuate uterus is a caudally fused uterus comprising of two separate cavities. Complete bicornuate uterus is a type of Mullerian duct deformity, resulting from abnormal duct fusion. In the septate uterus, a number of serious adverse outcomes can happen but in the case of a heart-shaped uterus i.e. bicornuate uterus, a woman usually can give birth safely. As a result, the lower part of the uterus is unitary while the upper part is bifurcated. “As the pregnancy grows, it distorts everything and becomes more challenging to diagnose,” says Hobson.

Uterus didelphys – a double uterus that may also be associated with a double cervix and/or vagina. A bicornuate uterus consists of two symmetric uterine horns unified by caudal fusion. Complete uterine septa that extend either to the internal or external cervical os are known as bicornuate unicollis uterus and bicornuate bicollis uterus, respectively. This condition mainly affects the reproductive capability of women. A double uterus may have one opening (cervix) into one vagina, or each uterine cavity may have a cervix. It means ‘horn.’ The bicornuate uterus is also called a heart shaped uterus, in which case the uterus is made up of two shapes that look like horns and are separated by a septum. II.
