Situs inversus totalis (SIT) is a rare syndrome in which all the organs are mirrored in the body. It occurs with an estimated frequency in 1 to 2 births per 10,000. Unlike situs inversus, all organs are involved.

In this case, the patient's heart was found on the right side of the chest, which is known as situs inversus with dextrocardia. In these situations, the affected organ usually has anomalies, whereas in SIT, the organs usually function correctly and the patients are usually otherwise healthy.

SIT is most often described as part of the ciliary dyskinesia syndrome, also known as Kartagener syndrome (situs inversus, bronchiectasis, sinusitis), usually diagnosed during childhood.
