Anatomy of a dextrocardia case with situs solitus.

Internally there were four cardiac chambers, with absence of septal communication. 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. In solitux, authors classify dextrocarcia alterations as a direct consequence of dextrocardia associated to multiple cardiac malformations Bernasconi et al. Situs solitus is the normal position of thoracic and abdominal organs.

The auricles and atriums were opened and analyzed and disclosed normal anatomical aspects.

The lesser anteater Dextroccardia tetradactila is a Xenartra from the Myrmecophagidae family. Unsourced material may be challenged and removed. It should not be used for medical advice, diagnosis or treatment.

Our findings corroborate the dextrocarria author, however, we did not find multiple malformations, only the shunting of pulmonary veins to the left ventricle as mentioned before. Articles needing additional references from March All articles needing additional references. This anomalous rotation of the heart made the pulmonary trunk emerge from the right ventricle abnormally, appearing much more superficial and extensive Figure 1.

Complete reversal of all organs is known as situs inversuswhile reversal of some organs but not others is called situs ambiguus or heterotaxy. Services on Demand Journal. What kidney problems can occur in babies?

Study Association This study is not associated with any graduation program. Sources of Funding There were no external funding sources for this study. Dextrocardia in situs inversus totalis with obstructive coronary disease. The aortic arch dextrocqrdia it on the right and the ascending aorta leaves the left ventricle in the caudo-cranial direction, from the right to the left da Silva et al.

While prenatal tests can detect some birth defects, many are not found immediately. With the exception of the brachiocephalic trunk, which presented a more accentuated angulation than the normal one, no other variations regarding position or trajectory were observed Figure 1.

What is dextrocardia with situs solitus?

This content reflects information from various individuals and organizations and may offer alternative or opposing points of view. It possess head, members and back with a yellowish coloration, while the remainder of the body is black, forming a kind of vest, long and prehensile tail and thoracic members with four great claws.

The abdominal cavity was open and the position of the viscera was normal, without any type of siyus, which characterized situs solitus. The exception was for the pulmonary veins that penetrated directly in the left ventricle, not passing for the atrium. How to cite this article.

The cause of most birth defects is unknown, though genetics and environmental factors can play a role. Views Read Edit View history. This condition – which is known as blue baby — happens when a baby doesn’t have enough oxygen, but transposed arteries are not the only reason it happens.

The fact of the base-apex inverted axis makes this finding more uncommon. The transposition of the great arteries is one of the common abnormalities associated with dextrocardia. Geographically, this species is distributed to the east of the Andes, in Venezuela, until the north of Argentina.

The main vases of the base were identified with some topographic alterations resulting in: A population-based study of cardiac malformations and outcomes associated with dextrocardia.

The aorta was dorsally located to the cava caudal vein, the pulmonary artery was cranial and dorsal to the aorta, the pulmonary veins in number ofthree were eolitus to soliths pulmonary artery, the cava caudal vein placed in the ventral plane and the cava cranial vein in the dorsal plane, both in relation to the other vessels Figure 1 C and 2 A and B. Can Med Assoc J. The left ventricle, which is the stronger portion of the heart, normally pumps blood to the entire body. Such alterations had not been found in this animal because the heart presented an apex-based rotation axis.

The wall of the left ventricle LV was thicker than the right ventricle RV similar to this organ’s normal anatomy Figure 1 C.

This malformation is caused by an anomalous rotation of the primitive heart tube to the left, in which the bulboventricular loop bends to the left, in a specular image of the normal condition, which occurs dextrocadria the 8 th week of embryonic life 1,2. Introduction Dextrocardia is rextrocardia embryologic malformation characterized by the displacement of the largest axis base to apex of the heart to the right solituus of the chest, with reversion of the apical inclination.

Its habits are predominantly nocturnal and the feeding basis for these animals is insects, mainly ants and termites Reis et al. The literature presents a great diversity of types and classifications for dextrocardia cases.
