    Bicornuate Uterus: A Comprehensive Guide on Causes, Symptoms and Treatment Options

    Updated on 3 November 2023

    Bicornuate uterus, also known as a heart-shaped womb, is a condition where the uterus is heart-shaped. About 3% of women worldwide have this congenital abnormality, which means it is something they are born with. Most women usually don’t figure out they have this condition until pregnancy because it usually doesn't cause any symptoms.

    In this article, we will understand in detail about its meaning, types, symptoms, potential risks in pregnancy and precautions to take for a smooth journey.

    What is a Bicornuate Uterus?

    The simplest meaning of bicornuate uterus is an abnormality that divides your uterus into two separate parts, or "horns," by a septum to give it a heart shape.

    The exact cause of this condition is not well understood, but it is thought to occur during the early development of the uterus in the womb. Some research suggests that it may be caused by a failure of the uterus to fuse properly during fetal development, while other studies have suggested a genetic link.

    Bicornuate Uterus Types

    Let us now understand the two types of heart-shaped uterus:

    1. Bicornuate Unicollis Uterus

    It is a subtype of bicornuate uterus characterised by a septum dividing the uterus into two "horns", and the cervix is fused to the septum. It is considered a rare variation and posses a lower risk.

    2. Bicornuate Bicollis Uterus

    It’s another subtype that divides the uterus into two "horns", and the cervix is in two separate parts. This condition is also a rare variation that causes similar issues but is less severe than the bicornuate uterus.

    Bicornuate Uterus Symptoms

    Some women with a bicornuate uterus may have no symptoms at all and may not even be aware of the condition. However, in some cases, it can cause the possible symptoms:

    How is a Bicornuate Uterus Diagnosed?

    A bicornuate uterus can be diagnosed through various imaging options, including ultrasound, magnetic resonance imaging (MRI), hysteroscopy, or a pelvic exam. These tests help visualize the shape and structure of the uterus and determine if it is heart-shaped or has a double uterus.

    Bicornuate uterus ultrasound and MRI are the preferred methods for imaging uterine anomalies like a bicornuate uterus. During these imaging tests, the doctor can identify the external contour of the uterus, which is typically concave or heart-shaped. Accurate diagnosis is essential for appropriate management and treatment of the condition.

    Potential Risks in a Bicornuate Uterus Pregnancy

    The condition can cause numerous complications during pregnancy including:

    1. Miscarriage

    Increases the risk of miscarriage, especially in the first three months.

    2. Preterm labor

    A condition when labor begins before 37 weeks of pregnancy.

    3. Placental problems

    Placenta is a temporary organ that develops to provide oxygen and nutrients to the baby. Bicornuate uterus can cause bleeding during pregnancy and even separate the placenta from the uterus.

    4. Breech position

    The baby could be in a breech position. This could require a cesarean delivery.

    5. Umbilical cord prolapse

    A rare but serious complication where the umbilical cord drops through the cervix ahead of the baby.

    Precautions for Bicornuate Uterus Pregnancy

    If you are pregnant and have been diagnosed with a bicornuate uterus, here are certain precautions that you can take to ensure a healthy pregnancy:

    • Receive regular prenatal care to monitor any complications.

    • Take prescribed medications to help prevent preterm labour, pain or discomfort.

    • Work with the doctor to monitor the baby’s position. Head-first is an ideal position.

    • Report contractions to the doctor, as there is always a higher risk of preterm labour.

    • Prepare a delivery plan in advance.

    Remember, a bicornuate uterus can cause complications during pregnancy. But many women with this condition have successful pregnancies with proper management.

    Treatment Options for Bicornuate Uterus

    There are three common treatment options for bicornuate uterus:

    1. Bicornuate uterus surgery

    Strassman metroplasty is a surgical procedure aimed at correcting the anatomical abnormality of the bicornuate uterus. It involves removing the septum that divides the two horns of the uterus, thus creating a more normal uterine cavity. Strassman metroplasty can improve pregnancy outcomes and reduce the risk of complications associated with bicornuate uterus.

    2. Cervical cerclage

    This procedure involves stitching the cervix closed to prevent premature dilation and miscarriage. Cervical cerclage is often recommended for women with bicornuate uterus who have a history of preterm labor or pregnancy loss. It helps to provide support to the cervix and reduce the risk of complications.

    3. Myomectomy

    In some cases, bicornuate uterus may be associated with the presence of uterine fibroids. Myomectomy is a surgical procedure that involves removing these fibroids from the uterus. By addressing the fibroids, myomectomy can help improve fertility and pregnancy outcomes in women with bicornuate uterus.

    It's important to note that the choice of treatment depends on individual factors, such as the severity of the condition and the patient's reproductive goals. A thorough evaluation by a healthcare professional is necessary to determine the most appropriate treatment plan for each individual.

    The Bottomline

    In conclusion, a bicornuate uterus is a rare congenital condition characterized by a heart-shaped uterus with a deep indentation at the top. While it may not always cause significant concerns, it can increase the risk of complications during pregnancy, such as recurrent pregnancy loss and preterm labor. But with correct diagnosis and treatment, women with bicornuate uterus can go on to have a healthy pregnancy.
