WARNING

The interpretation of wall motion abnormality is difficult and requires experience. This chapter is only indicative and you should not try to analyze walls motion. If you need to assess walls motion or if you suspect an abnormality, you must ask for a reference echo realized by an experimented sonographer and interpreted by an experienced cardiologist.


LV walls segmentation:

In 2002, the American Heart Association Writing Group on Myocardial Segmentation and Registration for Cardiac Imaging, recommended a 17-segment model for LV segmentation.
