Situs Solitus: Causes & Reasons

Possible Causes for Situs Solitus

Situs solitus is the normal position of thoracic and abdominal organs. [en.m.wikipedia.org]

This is indicative of situs solitus. [thoracickey.com]

In situs ambiguous (situs indeterminatus or heterotaxia), there is abnormal arrangement of the organs and major blood vessels, which is different from that of situs solitus [ncbi.nlm.nih.gov]

Dextrocardia

The incidence of dextrocardia associated to situs inversus in the general population is usually 1:10,000, whereas the one associated with situs solitus is 1:30,000 live births [scielo.br]

Familial dextrocardia with situs solitus is extremely rare entity. Dextrocardia offers a difficult situation to surgeon. [ncbi.nlm.nih.gov]

We report a case of a patient with dextrocardia, situs solitus, rheumatic heart disease, severe mitral regurgitation, moderate pulmonary artery hypertension, and severe left [ncbi.nlm.nih.gov]

Mesocardia

Situs Solitus Because atrial situs and abdominal situs are usually concordant, atrial situs solitus can be inferred at the bedside with percussion of a left-sided stomach, [clinicalgate.com]

[…] and abnormal spleen; 4 of mixed mesocardia with atrial situs solitus and ventricular inversion, with situs solitus of viscera with or without abnormal spleens; 1 of presumptive [ajconline.org]

Presumably, chance alone decides between situs inversus and situs solitus in homozygotes of the syndrome. [ommbid.mhmedical.com]

In the remaining PCD patients, there may be no rotational defects (situs solitus) or there may be a gradient of less extreme rotational defects with only 1 or a few organs [hosppeds.aappublications.org]

Situs Inversus Abdominalis

The incidence of situs inversus is reported to be 1:2500 to 1:20,000. Dextrocardia with situs solitus is less common. [bcm.edu]

Situs solitus is the normal position, and situs inversus is the mirror image of situs solitus (see the image below). Cardiac situs is determined by the atrial location. [emedicine.medscape.com]

Levocardia is not synonymous with situs solitus, although most patients with situs solitus have levocardia. 2- Dextrocardia: Cardiac apex is on the right. [fetalultrasound.com]

Situs Inversus

Situs solitus is the medical term referring to the normal position of thoracic and abdominal organs. [en.wikipedia.org]

The incidence of situs inversus is reported to be 1:2500 to 1:20,000. Dextrocardia with situs solitus is less common. [bcm.edu]

Like dextrocardia with situs solitus, situs ambiguus occurs in one in 20,000 births [source: Fuster, et al ]. [health.howstuffworks.com]

Transposition of the Great Vessels

In addition, it assesses the similarity in age of diagnosis, symptoms and problems of those with situs inversus (PCD-SI) and those with situs solitus (PCD-SS). [ncbi.nlm.nih.gov]

The normal left-right anatomic positioning, situs solitus, sometimes does not occur normaly, leading to laterality defects. [ncbi.nlm.nih.gov]

With these mutations, approximately 50% of PCD patients present with situs solitus and the remaining patient population having either situs inversus or situs ambiguus (‘ambiguous [pcdfoundation.org]
