Is situs inversus a medical condition?
Situs inversus is a rare genetic condition in which the organs in your chest and abdomen are positioned in a mirror image of normal human anatomy. Nearly all of the organs in your chest and abdomen develop in your body in a left-right formation. In situs inversus, your organs develop in a right-left formation.
Does situs inversus affect the brain?
Yet individuals with anatomical reversals in brain structure, due to a condition called situs inversus totalis, still retain left-sided language processing [4]. These results suggest that, for some cognitive tasks, function may not follow structure.
What are the long term effects of situs inversus?
Because the organs can be functional in situs inversus, it's possible for a person to have no complications. Other patients can experience cardiac dysfunction or a lung condition called primary ciliary dyskinesia (PCD), which causes mucus buildup in the lungs. This can lead to chronic bronchitis and sinusitis.

What is dextrocardia? In dextrocardia, the heart is positioned on the right side of the chest instead of its normal position on the left side. Dextrocardia on its own does not usually cause problems, but it tends to occur with other conditions that can have serious effects on the heart, lungs and other vital organs.
Why is situs inversus a symptom of OCD?
The underlying basis for situs inversus totalis in PCD has been attributed to dysfunction of the embryonic nodal cilia that play a key role in directing normal rotation of viscera. Without functional nodal cilia, thoracoabdominal laterality becomes random.
Is situs inversus hereditary?
Dextrocardia with Situs Inversus, a rare condition that is present at birth, is transmitted by autosomal recessive genes.
Are people with situs inversus more likely to be left handed?
Situs inversus (SI) of the visceral organs can occur with Primary Ciliary Dyskinesia (PCD), due to mutations which affect left-right axis formation. Roughly 10% of people with SI and PCD are left-handed, similar to the general population. However, in non-PCD SI, the rate of left-handedness may be elevated.
Can you live with your heart on the right side?

What is situs solitus?
The normal arrangement of internal organs is known as situs solitus. Although cardiac problems are more common, many people with situs inversus have no medical symptoms or complications resulting from the condition, and until the advent of modern medicine, it was usually undiagnosed.
Can a person with situs inversus have all their great vessels reattached to the donor heart?
For example, a person with situs inversus who requires a heart transplant needs all their great vessels reattached to the donor heart. However, the orientation of these vessels in a person with situs inversus is reversed, necessitating steps so that the blood vessels join properly.
Does situs inversus complicate organ transplantation?
Situs inversus also complicates organ transplantation operations as donor organs will more likely come from situs solitus (normal) donors. As hearts and livers are chiral, geometric problems arise placing an organ into a cavity shaped in the mirror image. For example, a person with situs inversus who requires a heart transplant needs all their great vessels reattached to the donor heart. However, the orientation of these vessels in a person with situs inversus is reversed, necessitating steps so that the blood vessels join properly.

Is Situs Inversus a sporadic disease?
Most cases of this disease are sporadic, apart from Karta gener Syndrome . Once it appears in pregnancy, it does not show any sign of recurrence in later maternities. In such cases, there can be a new, self-generated mutation or participation of multiple genes in association with environmental factors that collectively influence the appearing of this disease. Several genes of different varieties involved in the procedure of determining the normal intrauterine development direction have been located. Damage to any of these can give rise to Situs Inversus.

Effect on anatomy
The condition affects all major structures within the thorax and abdomen. Generally, the organs are simply transposed through the sagittal plane. The heart is located on the right side of the thorax, the stomach and spleen on the right side of the abdomen and the liver and gall bladder on the left side. The heart's normal right atrium occurs on the left, and the left atrium is on the right. The lung anatomy is reversed and the left lung has three lobes while the right lung has two lobes. The inte…
Diagnosis
Diagnosis of situs inversus can be made using imaging techniques such as x-ray, ultrasound, CT scan, and magnetic resonance imaging (MRI).
Any potential treatment for situs inversus would involve a complete and highly invasive surgical rearrangement of the internal viscera of the patient. Such a procedure is unnecessary, given that situs inversus rarely causes any additional symptoms. No treatment, medical or surgical, is pres…
Epidemiology
Situs inversus is very rare, affecting 0.01% of the population. This is equivalent to 1 in 10,000 people.
History
Dextrocardia (the heart being located on the right side of the thorax) was seen and drawn by Leonardo da Vinci, and then recognised by Marco Aurelio Severino in 1643. Situs inversus was first described more than a century later by Matthew Baillie.
Etymology
The term situs inversus is a short form of the Latin phrase situs inversus viscerum, meaning "inverted position of the internal organs".
