Sternopericardial ligaments

Sternopericardial ligaments are fibrous bands of connective tissue that connect the pericardium to the posterior surface of the sternum. They are part of the mediastinum, the central compartment of the thoracic cavity, and play a role in stabilizing the position of the heart within the thorax.

Anatomy

The sternopericardial ligaments are typically divided into superior and inferior ligaments. The superior sternopericardial ligaments extend from the superior part of the pericardium to the manubrium of the sternum. The inferior sternopericardial ligaments, on the other hand, extend from the inferior part of the pericardium to the body of the sternum.

Function

The primary function of the sternopericardial ligaments is to stabilize the position of the heart within the thoracic cavity. They prevent excessive movement of the heart, particularly during physical activity, and help maintain the heart's alignment with the great vessels.

Clinical significance

Due to their location and function, sternopericardial ligaments can be involved in various medical conditions. For instance, they can be affected in cases of pericarditis, an inflammation of the pericardium, or mediastinitis, an inflammation of the tissues in the mediastinum. They can also be involved in surgical procedures involving the heart or mediastinum.
