What is situs solitus dextrocardia?
Dextrocardia refers to a heart positioned in the right side of the chest. Situs solitus describes viscera that are in the normal position, with the stomach on the left side; in situs inversus, the positions of the abdominal organs and viscera are reversed.
How common is situs inversus with dextrocardia?
As it is recessive genes that cause dextrocardia, an individual must inherit a copy of the abnormal gene from both parents to develop the condition. Dextrocardia affects an estimated 1 out of every 12,000 people . Dextrocardia situs inversus totalis affects approximately 1 out of every 10,000 children.
What does situs solitus mean?
Situs Solitus: normal arrangement of viscera and atria, with RA right-sided and LA left-sided. Solitus = usual, or- dinary, customary hence normal. Situs Inversus: inverted arrangement of viscera and atria, with RA left-sided and LA right-sided, as in a mirror-image of situs solitus.
What does situs inversus look like?
What is situs inversus? 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.
What is situs solitus in ultrasound?
Situs solitus is the normal arrangement of abdominal organs with levocardia (Fig. 3) and is associated with a less than 1% incidence of congenital heart disease.
What is situs in heart?
Situs describes the position of the cardiac atria and viscera. 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.
Is situs solitus levocardia normal?
Is situs inversus a disease?
Genetic Disease. Situs inversus is a genetic disease, which means that it is caused by one or more genes not working correctly.
What situs means?
the location of property
Situs means the location of property or an item for legal purposes. Where the situs of something is depends on the type of item and can have important legal consequences. For most physical items the situs is the place where the object is located presently such as a house or a purse.
What is levocardia and dextrocardia?
In levocardia, the heart is predominantly in the left hemithorax with a leftward apex. In dextrocardia, the heart is predominantly in the right hemithorax. Primary dextrocardia is defined as a condition in which the heart is in the right hemithorax due to a structural congenital heart defect.
What are the symptoms of dextrocardia?
Dextrocardia Symptoms
- Breathing problems.
- Cyanosis (bluish skin due to not enough oxygen in the blood)
- Failure to grow and gain weight.
- Fatigue, especially when feeding.
- Frequent sinus or lung infections.
- Jaundice (yellow skin and eyes)
- Pallor (very pale skin)
What is the relationship between dextrocardia and abdominal situs solitus?
Dextrocardia could be associated with abdominal situs solitus or inversus (isolated dextrocardia has a strong association with congenital heart disease).
What is the difference between situs solitus and situs inversus?
Situs solitus describes viscera that are in the normal position, with the stomach on the left side; in situs inversus, the positions of the abdominal organs and viscera are reversed. Dextrocardia with situs solitus occurs in an estimated 7500–29 000 living people worldwide.
What is isolated dextrocardia?
Isolated dextrocardia, the condition of right-sided heart with situs solitus is most commonly referred to as dextroversion. Case Presentation A 2-month-old Ugandan baby boy discovered to have isolated dextrocardia with situs solitus presented with fever, cough, and difficulty in breathing.
How to identify Cardiac situs in dextrocardia and levocardia?
In dextrocardia, the right hemidiaphragm will be at lower level compared with left side, whereas in levocardia the left hemidiaphragm will be at lower level. This is because the cardiac apex pushes the diaphragm downwards. 1 So identification of cardiac situs should be based on where the cardiac apex is pointing to and level of diaphragm.
