LOINC Code 78950-3: Left ventricle Segmental wall motion panel by Angiogram

78950-3 is a LOINC code used to identify Left ventricle Segmental wall motion panel by Angiogram in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Segmental wall motion panel. It is commonly used with the system or sample type Heart.ventricle.left.

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Segmental wall motion panel. It is commonly used with the system or sample type Heart.ventricle.left.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Order
  • Panel type: Panel
  • Method: Angiogram

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

Left ventricle Segmental wall motion panel by Angiogram
Segmental wall motion panel
The American Heart Association (AHA) recommends assessing left ventricular wall motion by angiography using a seven segment model with right and left anterior oblique views, compared to the 17 segment model the AHA recommends for assessing segmental wall motion by echocardiography. The seven segments of the left ventricle wall are as follows1) anterobasal wall; 2) anterolateral wall; 3) apical wall; 4) diaphragmatic or inferior wall; 5) posterobasal wall; 6) septal wall; and 7) posterolateral wall. [PMID: 1116248] When mapping be aware that the wall segments used in angiography are different from those in echocardiography and we have different LOINC codes for each method.
