Coronary angiographic views

Coronary angiographic views Coronary angiography is done in multiple projections or views to get a three dimensional idea of the coronary lesions. Some regions of the coronary arteries may appear foreshortened in certain views so that true length of the lesion may not be appreciated. Actual severity of eccentric stenosis can be ascertained only by multiple orthogonal views. Even though there are several conventional views for coronary angiography, unusual angulations may be needed in an individual case to guide coronary interventions. Often a test shot is given before the actual cine run to see if the branches are overlapping or not. Common projections used in coronary angiography are left anterior oblique (LAO), right anterior oblique (RAO), postero-anterior (PA or AP), and lateral views. In addition to these, varying degrees of cranial or caudal angulations can be added to these views. In general, proximal parts of the major vessels are best seen in caudal projections. Views for left coronary angiography  Spider view or LAO caudal view is often the first view taken during coronary angiography. This view is useful in visualising the left main coronary artery and its bifurcation into left anterior descending (LAD) coronary artery and left circumflex (LCX) coronary artery. LAO angulation may vary from 40-50º and caudal angulation 25-40º [1]. Spider view – LAO caudal view of left coronary angiogram LAO caudal view of left coronary angiogram resembles a spider and h...
