Overview
Left Coronary Artery
The left main coronary artery gives rise to the left anterior descending artery and the left circumflex coronary artery. Complete visualization of these arteries and their branches requires care and rigor to ensure complete anatomical documentation. Often bifurcations and vessel foreshortening and overlap cause errors in stenosis estimation. There are no steadfast rules in which tomographic views are most useful. Generally, for circumflex and proximal epicardial visualization the caudal views are most useful. For LAD and LAD/diagonal bifurcation visualization the cranial views are most useful. Overall, if there is not a significant limitation on contrast utilization, standard 'around the world' angiography using a selection of the following angiographic views will document left coronary anatomy.
