Key result
Radiographs differentiate dextrocardia with situs inversus from dextroposition secondary to hiatus hernia.
Why the study?
Confusing terminology regarding heart position and apex direction in cases of dextrocardia and dextroposition complicates diagnosis and description.
Case Report (n=2)
Differentiating dextrocardia from dextroposition on chest radiographs is important for accurate anatomical description.
Emphasizes precise terminology to distinguish dextrocardia from dextroposition on radiographs; leaves open standardized nomenclature validation.
At first glance these chest radiographs appear similar. Closer inspection suggests ‘dextrocardia’ (figure 1A) and ‘dextroposition’ (figure 1B). Figure 1 Chest radiographs from two men in their 70s incidentally found to have dextrocardia with situs inversus (A) and dextroposition with a hiatus hernia (arrow) (B). Confusing terminology is helped if the heart's position within the thorax and point of direction of the apex is described.1 A heart and apex on the left is termed ‘levocardia’, …
