The<unk>  main<unk>  artery gives rise to the<unk>  anterior descending (LAD) artery and the<unk>  circumflex<unk>  (LCx) 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<unk><unk>  anatomy.
Coronary angiography left coronary artery
Coronary angiography right coronary artery
Chronic stable angina electron beam tomography
Left ventricular hypertrophy echocardiography
Coronary heart disease electrocardiogram
Coronary angiography quantitative angiography
Carotid artery stenosis electrocardiogram
Carcinoid syndrome electrocardiogram
