This means that when viewing the heart through a mirror, what you see is indistinguishable from the heart itself. We can be more precise about this, and describe the operation – ‘the reflection’ – that may be applied to the heart without changing its appearance. Reflecting in the heart’s vertical centre line, i.e. exchanging its left-hand and right-hand sides, leaves it unchanged.
