Anterior left ventricular wall and apex
Territory
The largest single territory, fed by the LAD trunk and its diagonals; the apex is where LV aneurysm and mural thrombus form after an anterior infarct.
Traced from the start
- Left (posterior) aortic sinus and left main stem
- Left anterior descending (anterior interventricular) artery
- Diagonal branches of the LAD
- Anterior left ventricular wall and apex
Detail
- Supplied by
- LAD trunk and diagonal branches
- Leads
- V3 and V4 (anterior), spreading to V5 and V6 at the apex
When it goes wrong
Large anterior MI
LV aneurysm with ST elevation persisting beyond two weeks, mural thrombus and embolic stroke
Transmural anterior MI on day 3 to 7
Free wall rupture with tamponade and pulseless electrical activity
