What does situs inversus look like?

In isolated situs inversus (occurring alone with no other abnormalities), there is a complete mirror image transposition of the thoracic (chest) and abdominal organs , and anterior-posterior (front-back) symmetry is normal. Many affected people have no associated health issues when the condition is isolated.

How do you confirm situs inversus?

The stomach (S) bubble is visible in the right upper quadrant. Confirming a mirror-image position of the atria allows confident diagnosis of situs inversus if the viscera are also reversed. The atrial morphology cannot be discerned on chest radiographs, but it can be determined indirectly by evaluating the bronchi.

How rare is situs inversus?

Situs inversus is a very rare condition. According to an article in the journal Heart Views , it occurs in an estimated 1 in 10,000 people.

Can you get pregnant with situs inversus?

There were 6 pregnancies in 3 patients with situs inversus and 9 pregnancies in 6 patients with isolated dextrocardia. There were no apparent antenatal complications. None of the patients developed any cardiac symptoms antenatally.

How long can you live with situs inversus?

Treatment of Dextrocardia with Situs Inversus is symptomatic and supportive when needed. In most cases, affected individuals can live a normal life without any symptoms or discomfort. If the condition is associated with other more serious heart malformations, the prognosis and treatment will vary.

Can you live with situs inversus?

In the absence of congenital heart defects, individuals with situs inversus are homeostatically normal, and can live standard healthy lives, without any complications related to their medical condition.

Why does Kartagener cause situs inversus?

Kartagener’s syndrome is a rare, autosomal recessive genetic ciliary disorder comprising the triad of situs inversus, chronic sinusitis, and bronchiectasis. The basic problem lies in the defective movement of cilia, leading to recurrent chest infections, ear/nose/throat symptoms, and infertility.

What is situs inversus in anatomy?

Situs inversus is a condition in which the arrangement of the internal organs is a mirror image of normal anatomy. It can occur alone (isolated, with no other abnormalities or conditions) or it can occur as part of a syndrome with various other defects.

What are the types of visceral situs?

Visceral situs refers to the pattern of arrangement of the body organs relative to the midline. There are four types of visceral situs: situs solitus, situs inversus, heterotaxy with thoracic right isomerism, and heterotaxy with thoracic left isomerism (Fig.

Which chest radiography findings are characteristic of situs inversus (Si)?

In most patients with situs inversus, chest radiography shows dextrocardia, with the cardiac apex pointing to the right and the aortic arch and stomach bubble located on the right as well. (See the image below.) Posteroanterior chest radiograph in a 40-year-old man with situs inversus and dextrocardia.

What is the difference between situs solitus and situs inversus dextrocardia?

Isolated dextrocardia is also termed situs solitus with dextrocardia. The cardiac apex points to the right, but the viscera are otherwise in their usual positions. Situs inversus with dextrocardia is also termed situs inversus totalis because the cardiac position, as well as the atrial chambers and abdominal viscera,…
