What is inversus totalis?

What is inversus Situs?
General Discussion. Dextrocardia with Situs Inversus is a rare heart condition characterized by abnormal positioning of the heart. In this condition, the tip of the heart (apex) is positioned on the right side of the chest.
How common is situs inversus totalis?
Situs inversus totalis has an incidence of 1 in 8,000 births. Situs inversus with levocardia is less common, with an incidence of 1 in 22,000 births. When situs cannot be determined, the patient has situs ambiguous or heterotaxy.
Is situs inversus totalis rare?
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.
What is situs inversus caused by?
Situs inversus is caused by an autosomal recessive genetic condition. An unaffected carrier mother and an unaffected carrier father have a 1 in 4 chance of having a child with situs inversus. Because many genetic steps would have to come together to cause situs inversus, the condition is rare.
How is situs inversus acquired?
An acquired cause resulting from an in utero insult that interrupts the normal process of differentiation and orientation has been postulated in view of the frequent association between abnormal situs and other rare congenital defects.
What is the cause of situs inversus?
Is Levocardia normal?
Levocardia is a medical condition where the heart is on the normal side of the body (the left), as opposed to dextrocardia, in which the heart is in the right side of the thoracic cavity….

What causes situs inversus cilia?
Primary Ciliary Dyskinesia 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.
What is situs inversus with levocardia?
Situs inversus has two main subtypes: dextrocardia and levocardia. A person is said to have dextrocardia if the point of the heart is on the right side. A person is said to have levocardia if the heart is on the left side, yet the other organs are flipped.
How does situs inversus start?
Situs inversus is caused by an autosomal recessive genetic condition . An unaffected carrier mother and an unaffected carrier father have a 1 in 4 chance of having a child with situs inversus. Because many genetic steps would have to come together to cause situs inversus, the condition is rare. The condition is also seen in “mirror image” twins.
How is situs inversus treated?
No treatment is indicated for situs inversus unless the patient has congenital heart disease and associated complications, in which the specific therapy will depend on the cardiac anomaly and the clinical picture.
How common is situs inversus?
Situs inversus is a very rare condition. According to an article in the journal , it occurs in an estimated 1 in 10,000 people.
What does situs inversus mean?
Situs inversus is a genetic condition in which the organs in the chest and abdomen are positioned in a mirror image from their normal positions. For example, the left atrium of the heart and the left lung are positioned on the body’s right side.
