Importance in cardiovascular medicine:
the posterior aspect is a plane in which the heart is not often viewed until the
heart is manipulated in the body during a surgical procedure. However, it can
be displayed in modern imaging modalities such as CT and MR and is used to help
orientate catheters and leads during catheter lab procedures. The media display
the heart in both the valentine and attitudinally correct positions either in
the body or explanted. The pericardium, a double walled sac that protects and
lubricates the heart, can be seen in some of the media.
when positioned in the attitudinally correct orientation the left atrium and
ventricle can be seen most prominently as they lie in a more posterior position
than the left. The left atrium can be seen to the right of the image with the
right superior and inferior pulmonary veins entering the chamber from the right
of the image and the left from the left. The coronary sinus can be seen
running around the base of the heart between the left atrium and ventricle and
the inferior vena cava can be seen to the bottom of the image connecting to the
inferior portion of the right atrium.
