What is situs inversus Viscerum?
Situs inversus viscerum is that condition in which the normal arrangement of the viscera is reversed to form a mirror picture of the usual position. Such transposition is usually total but may in rare instances involve either the thoracic viscera or the abdominal viscera alone.
Does situs inversus affect life expectancy?
Generally, patients with situs inversus totalis are asymptomatic and have a normal life expectancy. [8] Documenting situs inversus in an individual is important in order to correctly interpret any future symptoms and avoid any inadvertent clinical or surgical mishap.
What is the difference between situs inversus and dextrocardia?
In people affected by dextrocardia, the tip of the heart points towards the right side of the chest instead of the left side. Situs inversus refers to the mirror-image reversal of the organs in the chest and abdominal cavity. Some affected people have no obvious signs or symptoms.
What are the complications 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.
Can situs inversus be cured?
In isolated situs inversus, no treatment may be necessary. When situs inversus is associated with another condition, treatment may depend on the associated condition and the signs and symptoms present in the affected person.
How do you treat inversus Situs?

How is situs inversus diagnosis?
A thorough physical examination, followed by radiographic imaging of the chest and abdomen and electrocardiography, identify most cases of situs inversus. The main diagnostic challenge in affected people is the non-traditional presence of referred pain (pain felt in a different location than its source).
How is situs inversus caused?
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.

What is s ITUs inversus viscerum?
S itus inversus viscerum is that condition in which the normal arrangement of the viscera is reversed to form a mirror picture of the usual position. Such transposition is usually total but may in rare instances involve either the thoracic viscera or the abdominal viscera alone.
What are the different types of visceral atrial situs?
The basic types of visceral atrial situs are demonstrated: situs solitus (A), situs inversus (B), and situs ambiguus with asplenia (C) and polysplenia (D).
