During coronary arteriography, which vessels are primarily visualized?

During coronary arteriography, the primary focus is on the coronary arteries. This procedure is specifically designed to visualize the blood vessels that supply the heart muscle itself. By using contrast agents and imaging techniques, clinicians can assess the presence of blockages, narrowing, or other abnormalities within these arteries, which is crucial for diagnosing heart conditions, such as coronary artery disease.

Coronary arteriography targets the left and right coronary arteries, allowing for detailed imaging of their branches. This detailed visualization helps in determining the extent of any vascular issues, guiding treatment decisions, and planning interventions such as stenting or bypass surgery if required.

While other vascular structures, such as the aortic arch or pulmonary arteries, play important roles in cardiovascular health, they are not the primary focus during coronary arteriography. The procedure is specifically tailored to assess the coronary circulation. Thus, the correct answer reflects the central aim of this imaging technique.
