Crista supraventricularis

Crista Supraventricularis

The Crista Supraventricularis is a prominent muscular ridge in the right atrium of the heart, extending from the front of the atrium and along the right side of the atrioventricular orifice. It is a significant anatomical feature of the cardiovascular system.

Anatomy

The Crista Supraventricularis is a part of the right atrium and is located in the heart. It is a muscular ridge that separates the tricuspid valve from the sinus venarum, which is the part of the right atrium that receives blood from the superior vena cava and inferior vena cava.

Function

The primary function of the Crista Supraventricularis is to direct the flow of blood in the right atrium. It guides the blood from the superior and inferior vena cava towards the tricuspid valve, which then leads to the right ventricle.

Clinical Significance

The Crista Supraventricularis is an important landmark in cardiac surgery, particularly in procedures involving the tricuspid valve or the right atrium. Its location and structure can also be affected by certain heart conditions, such as congenital heart disease and cardiomyopathy.
