Anatomia de um caso de dextrocardia com Situs Solitus

Abstract

We present a rare case of dextrocardia in the corpse of a female child, aged approximately one year old, presenting situs solitus. The cases of dextrocardia reported in the literature normally describe multiple associated cardiac malformations. 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. There was no atrioventricular discordance or other intra and extracardiac malformations, which are commonly seen in cases of dextrocardia. A large ductus arteriosus was found, as well as the anomalous position of the right portion of the heart.

Dextrocardia with situs solitus and inversion apex-basis axis in lesser anteater (Tamandua tetradactyla): case report

“…Faig- Leite et al, (2008), described a case of a human dextrocardic heart in a corpse of one year old, beyond the dextrocardia other anomalies were identified, like a great arterious duct. This condition was not found in the studied animal because there is no communication between the pulmonary artery and the aorta.…”

“…This infirmity can occur separately (situs solitus) or in association with situs inversus (complete inversion of all visceral organs) presenting itself as an inverted image (Da Silva et al, 1992) due to cardiac malformations (Bernasconi et al, 2005, Yusuf et al, 2009, Evans et al, 2010 or situs ambiguos (the liver and the stomach are located in the centre of abdominal cavity and the stomach develops behind the liver) (Faig-Leite, 2008), but according to Perloff (1978), these infirmity can only be called assitus invesus, however without necessarily occurring associated with cardiac malformations (Aiello et al, 2008).…”

Dextrocardia, situs solitus, inlet ventricular septal defect (VSD), and iatrogenic tricuspid regurgitation (TR)―A surgical perspective

“…It is of paramount importance to understand the relative arrangements of various chambers of heart, for a successful surgical outcome. Few case reports of situs solitus with dextrocardia have been cited 4,5 . However, literature highlighting the surgical management of an intracardiac defect with this morphology, including repair of the tricuspid valve, has not been reported to the best of our knowledge.…”

“…Few case reports of situs solitus with dextrocardia have been cited. 4,5 However, literature highlighting the surgical management of an intracardiac defect with this morphology, including repair of the tricuspid valve, has not been reported to the best of our knowledge. We describe a case of dextrocardia, situs solitus, inlet ventricular septal defect (VSD), and severe tricuspid regurgitation (TR) in a 21-year-old female, managed successfully.…”

Dextrocardia associada a dupla via de saída do ventrículo direito e transposição de grandes vasos: um relato de caso

“…A incidência da dextrocardia associada a situs inversus na população em geral é de 1:10.000, enquanto a associada a situs solitus é de 1:30.000 em nascidos vivos e de 1:900.000 na população adulta. Essa discrepância de incidências encontradas nos casos de situs solitus deve-se a maior ocorrência de doenças cardíacas e/ou extracardíacas associadas (FAIG-LEITE, 2008).…”
