What is Dextroversion of the heart?
DEXTROVERSION of the heart is a form. of dextrocardia resulting from con- genital malrotation of the heart about its long axis. The earliest reference to the condition is credited to Paltauf (1), who, in 1901, differentiated it from the other forms of dextrocardia.
What is cardiac malposition?
Cardiac malposition refers to any position of the heart other than a left-sided heart in a situs solitus individual.
What is dextrocardia?
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.
What is cardiac situs?
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.
What is Situs Solitus Levocardia?
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 the most common cause of cardiac malposition?
Generally, fetal cardiac malposition can be classified into two main types [1, 2]: One is caused by intrinsic congenital heart diseases, such as isolated dextrocardia, situs inversus, isolated levocardia, etc., while others are caused by extracardiac malformations such as unilateral lung agenesis, diaphragmatic hernia.
Is Mesocardia normal?
Mesocardia in an uncommon cardiac abnormality, in which the heart is positioned in the center of the thorax and its longitudinal axis lies in the thoracic mid-sagittal plane. The true incidence of this condition is unknown.
What is Heterotaxia?
Heterotaxy is a rare condition where many organs in the body can be formed abnormally, in the wrong position, or even missing. Many children with heterotaxy have complex heart defects, which are often the most challenging problems associated with heterotaxy.
What does situs mean in medical terms?
Situs inversus (also called situs transversus or oppositus) is a congenital condition in which the major visceral organs are reversed or mirrored from their normal positions.
What is normal situs?
Situs solitus is the medical term referring to the normal position of thoracic and abdominal organs. Anatomically, this means that the heart is on the left with the pulmonary atrium on the right and the systemic atrium on the left along with the cardiac apex.
