The patient\u2019s associated atrial septal defect (ASD) with left to right shunt leading to pulmonary congestion and recurrent episodes of pneumonia was the leading diagnosis for which care was sought at our hospital. The diagnoses of these rare congenital cardiac anomalies were uncovered only after a thorough workup. Mesocardia is extremely rare and accounts for only 0.2% of congenital anomalies. Its association with other cardiac and vascular anomalies, however, warrants a meticulous workup for the identification of such associated conditions\u2014ASD and double IVC being two such anomalies in our patient. The dictum of working up a case of congenital cardiac anomaly for other congenital cardiaovascular anomalies, therefore, found merit in our case.<\/jats:p>","DOI":"10.1136\/bcr-2022-249263","type":"journal-article","created":{"date-parts":[[2022,5,23]],"date-time":"2022-05-23T11:47:05Z","timestamp":1653306425000},"page":"e249263","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Rare case of mesocardia with ostium secundum ASD and double IVC"],"prefix":"10.1136","volume":"15","author":[{"given":"Shriram","family":"Kumar","sequence":"first","affiliation":[{"name":"Medicine, Gandhi Medical College and Hospital, Secunderabad, Hyderabad, Telangana, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shreyas Raghavan","family":"Nandyal","sequence":"additional","affiliation":[{"name":"Medicine, Gandhi Medical College and Hospital, Secunderabad, Hyderabad, Telangana, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3310-4792","authenticated-orcid":false,"given":"Sharanya","family":"Kaushik","sequence":"additional","affiliation":[{"name":"Bangalore Medical College, Bangalore, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9127-2738","authenticated-orcid":false,"given":"Sufyan","family":"Ibrahim","sequence":"additional","affiliation":[{"name":"Kasturba Medical College Manipal, Udupi, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2022,4,25]]},"reference":[{"key":"2025082711520628000_15.4.e249263.1","doi-asserted-by":"publisher","DOI":"10.1002\/ca.20652"},{"key":"2025082711520628000_15.4.e249263.2","first-page":"717-9","article-title":"A rare association: inferior vena cava anomalies and congenital heart diseases","volume":"43","author":"Ertu\u011frul","year":"2015","journal-title":"Turk Kardiyol Dern Ars"},{"key":"2025082711520628000_15.4.e249263.3","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(71)90006-3"},{"key":"2025082711520628000_15.4.e249263.4","doi-asserted-by":"crossref","first-page":"159","DOI":"10.1161\/01.CIR.56.2.159","article-title":"Cardiac malpositions.
