The arcuate uterus is a condition that affects women, causing a slight indentation in the upper part of the uterus. Sometimes referred to as a "heart-shaped uterus," this condition is not a serious concern for most women and is typically only discovered during a routine gynecological exam. There are several synonyms for the arcuate uterus, including a partially septate uterus, a uterine septum, or a subseptate uterus. While some women with this condition may experience fertility issues or complications during pregnancy, many are able to conceive and carry a healthy pregnancy to term without any issues.
