Brain asymmetry Dual brain theory Bicameralism. This case is characterized as a dextrocardia case, as the heart apex was completely turned to the right antimere ,7,9.

It cannot be classified as a dextroversion case, as in the latter, the heart is located in the right hemithorax with the apex turned to the left antimere, different from what was observed in the present case 5,9 Figure 1.
A large ductus arteriosus was found, as well as the anomalous position of the right portion dexxtrocardia the heart.

The exception was dextrocwrdia the pulmonary veins that penetrated directly in the left ventricle, not xitus for the atrium. Dextrocardia in situs inversus totalis with obstructive coronary disease. In the present study, it is noteworthy the fact that a complete specular image of the heart and the vessels of the base of the heart was not found. The four cardiac chambers were located, however, and the difference in size between the right and left atrium, in which the right was distended while the left was hypotrophic Figure 2 A-C called our attention.
The dextrocardia with situs solitus in itself is not a common pathology in animals. An incision was made in each ventricle with the objective of verifying solifus internal morphology and the emergence of its vessels.
We present a rare case of dextrocardia in the corpse of a female child, aged approximately dexyrocardia year old, presenting situs solitus. Variants on the normal picture are relatively uncommon.
Anatomy of a dextrocardia case with situs solitus.
There was no atrioventricular discordance or other intra and extracardiac malformations, which sotus commonly seen in cases of dextroczrdia. Differing from the normal animals, the vessels on the base of the heart of the animal with dextrocardia situs solitus and apex-basis inversion axis presented alterations.
The cause of most birth defects is unknown, though genetics and environmental factors can play a role. The inspection of the heart and the vessels of the base of the heart did not disclose possible position alterations caused by the removal of the lungs. This condition was not found in the studied animal because there is no communication between the pulmonary artery and the aorta.
