Technique and catheters.

This article reviews the current technique of coronary angiography, focusing on the choice of arterial access site; navigation from the arterial access site to the ascending thoracic aorta; cannulation of the native coronary arteries in their normal, variant, and anomalous locations; and cannulation of saphenous vein and arterial graft conduits. The authors conclude that, although no didactic training can substitute for the hands-on apprenticeship obtained during general cardiology and interventional cardiology fellowships, the intellectual elements fundamental to coronary angiography outlined here will result in a more efficient, effective, and safe procedure for patients.
