Conus artery

Conus Artery

The conus artery, a branch of the right coronary artery, is shown in this illustration from Gray's Anatomy.

The conus artery is a small branch of the right coronary artery that supplies blood to the conus arteriosus of the heart. It is one of the few arteries in the human body that does not have a corresponding vein.

Anatomy

The conus artery arises from the right coronary artery near its origin in the right aortic sinus. It travels upwards and to the right, following the contour of the conus arteriosus, a smooth-walled part of the right ventricle that directs blood into the pulmonary artery.

Clinical significance

The conus artery is typically small and its occlusion does not usually cause significant symptoms. However, in rare cases, occlusion of the conus artery can lead to myocardial infarction or heart failure.
