Coronary Artery Volume Score (CAVS): Explanation and Clinical Context The Coronary Artery Volume Score quantifies the total volume of the main coronary arteries (Left Main, Left Anterior Descending, Left Circumflex, Right Coronary Artery) as measured on coronary computed tomography angiography (CCTA).
It is used to assess the overall burden of atherosclerosis within the coronary circulation. Higher values indicate greater plaque and vessel remodeling and are associated with increased risk of cardiovascular events.
The score is calculated by summing the volumes of the four main coronary arteries, typically in milliliters (mL).
Clinical interpretation stratifies patients into low, intermediate, or high atherosclerotic burden categories, guiding preventive and therapeutic strategies.
