Left Atrium Anatomy

The most important discovery appears to be the fact that left sided pvs merge in a large proportion of patients into the common vestibule or antrum. Blood enters via the pulmonary veins and exits through the mitral valve.

Anatomy And Physiology Of The Heart

The left atrium is separated from the right atrium by the intertribal interatrial septum with the small depression the fossa ovale at the site of the closed foramen ovale.

Left atrium anatomy. The left atrium is located above left ventricle. The feasibility of treating atrial fibrillation with radiofrequency ablation has revived interest in the structure of the left atrium a chamber that has heen neglected in many texthooks of anatomy. Its primary roles are to act as a holding chamber for blood returning from the lungs and to act as a pump to transport blood to other areas of the heart.

Anatomy of the left atrium introduction. It is smaller by volume than the right atrium but with thicker walls. The left atrium is one of the four chambers of the heart located on the left posterior side.

The left atrial appendage is long and narrow. Lessons learned from sophisticated imaging techniques such as mra or cta suggest that the anatomy of the left atrium and pvs is very complex and individually highly variable. The walls of the left atrium are slightly thicker than the walls of the right atrium.
