Crista Supraventricularis[edit]

The crista supraventricularis is an important anatomical structure within the heart. It is a muscular ridge located in the right ventricle, separating the inflow tract from the outflow tract. This structure plays a crucial role in the proper functioning of the heart by directing blood flow from the right atrium to the right ventricle and then into the pulmonary artery.

Anatomy[edit]

The crista supraventricularis is situated above the tricuspid valve and extends towards the pulmonary valve. It is part of the right ventricular outflow tract (RVOT) and is essential in maintaining the separation between the inflow and outflow tracts of the right ventricle. This separation ensures that blood flows efficiently from the right atrium through the tricuspid valve into the right ventricle, and then from the right ventricle through the pulmonary valve into the pulmonary artery.

Function[edit]

The primary function of the crista supraventricularis is to support the structural integrity of the right ventricle and to facilitate the proper routing of blood. By maintaining the separation between the inflow and outflow tracts, it helps prevent the mixing of oxygen-poor blood returning from the body with the oxygen-rich blood being pumped to the lungs.

Clinical Significance[edit]

Abnormalities or defects in the crista supraventricularis can lead to various congenital heart defects or cardiac conditions. For instance, a prominent crista supraventricularis may be associated with right ventricular outflow tract obstruction (RVOTO), which can impede blood flow from the right ventricle to the pulmonary artery. Such conditions may require medical intervention or surgical correction to restore normal cardiac function.
