The right conus artery is a moderately-sized branch of the right coronary artery of the heart. It is given off proximally in the latter's course from the right coronary sinus, high in the atrioventricular groove on the sternocostal surface of the heart.
The conus artery passes superiorly and medially to supply the infundibulum of the right ventricle. It may anastomose with the left conus artery.
