The right coronary artery supplies blood to a part of the heart. To do this effectively, it branches off into smaller arteries, such as the conus artery and the sinoatrial nodal branch.

Your right coronary artery sends blood to the right side of your heart and also helps regulate your heartbeat. Branches from this artery also send blood to the middle of your heart.

The left coronary artery was normal in size, and the intima of the left descending and circumflex branches showed a few atheromatous plaques. The right coronary artery was markedly hypoplastic.
