Adopting attitudinally correct nomenclature for the left ventricular myocardium, such as renaming the 'anterior' wall to the superior wall, could resolve existing planar imaging registration problems.
Adopting attitudinally correct anatomical nomenclature for the left ventricle could resolve existing problems with orientation and registration across different cardiac imaging modalities.
May aid cross-modality LV imaging alignment clinically; leaves open prospective validation of nomenclature changes.
The American Heart Association recommends a model of the left ventricular myocardium based on 17 segments. The model is accepted and used by imagers in nuclear medicine, echocardiography, magnetic resonance imaging, and, more recently, in computed tomography. Some problems persist with the orientation and presentation of the planar imaging views between the modalities and with their registration with the segmental model. These problems would be eased if the "anterior" wall were to be called the superior wall, which is attitudinally correct. It would follow that the "anterior descending" and "posterior descending" arteries would be known as the superior and inferior interventricular arteries. This is also more correct anatomically, as is the need to describe the papillary muscles of the mitral valve as being positioned superiorly and inferiorly. In this review, we discuss these currently existing problems and make a plea for more stringent description and display of the planes used in imaging.

Partridge et al. (2008) conducted a review in Left ventricular anatomy and imaging. Attitudinally correct anatomical nomenclature was evaluated. Adopting attitudinally correct nomenclature for the left ventricular myocardium, such as renaming the 'anterior' wall to the superior wall, could resolve existing planar imaging registration problems.
