The Pericardial Artery is a small artery that supplies blood to the pericardium, the double-walled sac containing the heart and the roots of the great vessels. It is a branch of the thoracic aorta, the main artery of the chest.

Structure

The pericardial artery originates from the thoracic aorta and runs along the outer surface of the pericardium. It is typically small in size, but its size can vary among individuals. It provides oxygenated blood to the pericardium, ensuring the proper functioning of this protective sac.

Function

The main function of the pericardial artery is to supply oxygenated blood to the pericardium. This is crucial for the pericardium's role in protecting the heart and maintaining its position in the thoracic cavity.

Clinical significance

Damage or blockage of the pericardial artery can lead to pericarditis, inflammation of the pericardium, which can cause chest pain and other symptoms. Treatment typically involves addressing the underlying cause of the inflammation.
