Morphology
subendocardial = endocardial (transparent) = sub + endocardium
A straightforward prefixation: sub- 'beneath' attached to 'endocardial' meaning 'relating to the inner heart lining', yielding 'beneath the endocardium'.
Etymology
Subendocardial comes from the parts sub- 'under', endo- 'inside', and cardi- 'heart', the same root you see in cardiac. So subendocardial means 'under the heart's inner lining'.
