The ability to perform invasive diagnostic coronary angiography is a core requirement for cardiologists and fellows in training programmes. However, although key to their independence is the ability to obtain high-quality images that allow visualisation of the entire coronary vasculature, there exists no formal systematic method or teaching aid. This article provides an overview of the radiological equipment used in the catheter laboratory, details the naming of the different angiographic projections, and gives key tips and tricks to improve image quality. In addition, the coronary vasculature is broken down into segments, with descriptions provided of the essential views required to image each one. Using this approach, it aims to provide an essential aid to trainees and other healthcare professionals at the start of their careers.
