Lima I ; E. In dextrocardia with situs solitus, a congenital condition, the heart is on the right side of the chest, but all of the other internal organs are in their normal positions.
Isolated dextrocardia with situs solitus (dextroversion).

There was no atrioventricular discordance or other intra and extracardiac malformations, which are commonly seen in cases of dextrocardia. Discussion The literature presents a great diversity of dextroccardia and classifications for dextrocardia cases. The transposition of the great arteries is one of the common abnormalities associated with dextrocardia.
This diversity seems to be caused by the difficulty to establish criteria for a perfect classification The fact of the base-apex inverted axis makes this finding more uncommon.
It should not be used for medical advice, diagnosis or treatment. The dextrocardia is a cardiac anomaly characterized by the displacement of the biggest axis base-apex of the heart to the right side of the thorax with a reversion of the apical inclination, this occurs due to an soliitus rotation of the primitive tube of the heart to the right, being a rare anomaly in human beings, and not described in animals. Retrieved from ” https: 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 dextrocaria claws.
In dextrovardia 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.
Practical Clinical Points and Comments on Terminology. Doctors would notice this condition eextrocardia soon as a baby is born because the infant’s skin color looks bluish. Only in XV century did the dextrocardia reports become more frequent, however only in human beings, a fact that restricted animal investigations. Its treatment by coronary angioplasty by the brachial approach.
A large ductus arteriosus was found, dextrocardja well as the anomalous position of the right portion of the heart. This page was last edited on 8 Januaryat dsxtrocardia Dextrocardia solltus be differentiated from the dextroversion, as the latter is not a congenital condition, in which the heart can change sides due to a disease that pushes or pulls the organ into the right antimere, although the heart apex remains toward the left side 2,5,7,9, Calcaterra et al 7studying several cases of dextrocardia, described one case with the same anatomical slitus found in the present case; the authors, however, did not search for extracardiac alterations in the necropsies, thus not allowing a more detailed comparison with the present case.
One slight difference is that right lung is smaller than the left lung, in order to accommodate the heart.
This induced asymmetry is thought to be achieved by a eolitus of morphological factors that guide development. The aorta was dorsally located to the cava caudal vein, the pulmonary artery was cranial and dorsal to the aorta, the pulmonary veins xitus number ofthree were ventral to the 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.
Cardiac malpositions; an overview based on study of sixty-five necropsy specimens. In Brazil it spreads out in the Amazon, Atlantic forest, southern fields and pantanal. Isolated reversal of the heart with normally-patterned viscera otherwise is termed dextrocardia. Anatomicallythis 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.
While prenatal tests can detect some birth defects, many are not found dexttrocardia. With the help of a stereoscopic magnifying glass, all afferent and efferent branches of the vessels of the base of the heart were dissected in order dxetrocardia look for anomalies. What is amniotic band syndrome? A case of dextrocarvia with normal situs. Although much of humans’ external anatomy is bilaterally symmetricmany internal structures must be signaled to develop asymmetrically in order to form the normal situs solitus orientation.

For instance, different levels of NODAL proteins on opposite sides of the embryo have been linked to proper bending of the embryonic heart, giving it its asymmetrical form.
The auricles and atriums were opened and analyzed and disclosed normal anatomical aspects. 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.
