Analysis of visceral heterotaxy according to splenic status, appendage morphology, or both

We conclude, therefore, that description and analysis of visceral heterotaxy need to include considerations of the bodily organs as well as attention to cardiac structure. It must then be recognized that important differences exist between the groupings made on the basis of splenic status and morphology of the appendages. It is up to the individual investigator, based on the specific topic to be studied, to choose between the utilities of these different approaches.
