This hypothesis is supported by describing the anatomy of a complex patient with multiple laterality defects resulting in multiple cardiac and organ malformations. Case presentation: The unique aspect of the presented patient\u2019s morphological diagnosis lies in the presence of a leftward heart loop with an unusual shape and direction, with the right ventricle (RV) positioned posterosuperior to the left ventricle (LV). This configuration suggests congenitally corrected transposition of the great arteries, although it deviates from the typical presentation. Additionally, there is an arrest in the development of other embryonic structures, including an atrioventricular septal defect (AVSD) with asymmetric ventricles, hypoplasia of the left-sided morphological RV, and malposition of the great arteries, with the aorta positioned anteriorly and to the right of the stenotic pulmonary artery. There is also another important inconsistency: the atrial situs is solitus within the context of HS, accompanied by left bronchial isomerism, polysplenia, interrupted inferior vena cava, and bilateral superior vena cavae. Conclusions: In our patient\u2019s case, the segmental analysis revealed a rare morphological cardiac anatomy. Understanding both normal and pathological embryological cardiac development, and correlating it with the current morphological anatomy, was crucial in ensuring the correct diagnosis and treatment for our patient.<\/jats:p>","DOI":"10.47162\/rjme.67.2.12","type":"journal-article","created":{"date-parts":[[2026,9,15]],"date-time":"2026-09-15T18:08:14Z","timestamp":1789495694000},"page":"309-315","source":"Crossref","is-referenced-by-count":0,"title":["Embryological and morphological insights into diagnosing cardiac anatomy in heterotaxy syndrome"],"prefix":"10.47162","volume":"67","author":[{"name":"Department of Pediatric Cardiology, Emergency Institute for Cardiovascular Diseases and Heart Transplant, T\u00e2rgu Mure\u015f, Romania","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L\u0103cr\u0103mioara Eliza","family":"Chiperi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Toma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Pediatric Cardiology, Emergency Institute for Cardiovascular Diseases and Heart Transplant, T\u00e2rgu Mure\u015f, Romania; 3rd Pediatrics Department, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu Mure\u015f, Romania","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amalia","family":"F\u0103g\u0103r\u0103\u015fan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Pediatric Cardiology, Emergency Institute for Cardiovascular Diseases and Heart Transplant, T\u00e2rgu Mure\u015f, Romania; 3rd Pediatrics Department, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu Mure\u015f, Romania","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liliana","family":"Gozar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Pediatric Cardiology, Emergency Institute for Cardiovascular Diseases and Heart Transplant, T\u00e2rgu Mure\u015f, Romania; 3rd Pediatrics Department, George Emil Palade University of Medicine, Pharmacy, Science and Technology of T\u00e2rgu Mure\u015f, Romania","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alisa Ariana","family":"Tivadar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Pediatric Cardiology, Emergency Institute for Cardiovascular Diseases and Heart Transplant, T\u00e2rgu Mure\u015f, Romania","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"26736","published-online":{"date-parts":[[2026,9,8]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"\"[1] Sanders SP, Geva T.
