The patient, in medicine, is always L-R when looking at them, so that is important to remember. It may be your left, but you say the patient's right side.

If, in another meaning of observation, you tell by the position or directionality of the Aorta, Venae cavae, etc. Normally, the heart will be facing you as if it was a patient, whether on paper, replica, or actual heart.
