What is the typical sequence of steps in a routine diagnostic coronary angiography?

• A. Access, anticoagulation, aortography, engage coronaries, inject selective contrast in multiple views, interpret anatomy and plan intervention if needed
• B. Random order of steps
• C. Only engage coronaries and inject contrast
• D. Do not perform aortography

Answer: (B)

A routine diagnostic coronary angiography follows a deliberate, stepwise sequence to safely map the arteries. Start with obtaining arterial access and giving anticoagulation to prevent clotting as catheters are advanced. An aortogram is then performed to outline the aortic root and guide catheter selection and positioning. With the right catheters in place, the coronaries are engaged and selective contrast injections are made, typically from multiple views, so the entire course and any lesions can be seen in three dimensions. Finally, the images are interpreted to define the coronary anatomy, assess lesion severity, and decide whether intervention is needed. This order ensures safe catheter manipulation, provides comprehensive visualization from different angles, and supports efficient planning for treatment. Skipping an aortogram or imaging from only a single view would miss important context, and performing steps in a random order would be inefficient and potentially unsafe.
