LV perfusion territories

The regional distribution of LV segmental wall motion abnormalities detected by TEE can be used to help determine the location of disease within the coronary arteries. The diagram displays the typical territories of myocardium perfused by each of the major coronary arteries supplying the LV in the TEE mid-esophageal four-chamber view, TEE mid-esophageal two-chamber view, TEE mid-esophageal long-axis view, and TEE transgastric LV short-axis view. Anatomic variations and coronary collateral flow may produce different patterns of coronary perfusion in individual patients.
