Nettet27. jul. 2016 · Left isomerism, in contrast, is generally associated with multiple spleens (polysplenia syndrome) that are confined to only one side of the vertebral column. Occasionally, subjects with asplenia or polysplenia have normal hearts, and, rarely, those with atrial isomerism have normal spleens. Nettet1. jan. 2024 · Atrial isomerism is a very rare condition defined as symmetric development of normally asymmetric organs or organ systems.
