Location:
The ostium of the posterior vein of the left ventricle is typically near the distal end of the coronary sinus. In most human hearts we have observed a partial valve associated with this ostium, as this venous drainage enters the coronary sinus.

Function:
This cardiac vein returns deoxygenated blood (metabolic waste products) from the lateral wall of the left ventricle.

Importance in device delivery:
Left heart pacing can be achieved via placing leads into this vein; often one will try to access branches that are more posterior-lateral.

Localización:
El ostium de la vena posterior del ventrículo izquierdo suele estar cerca del extremo distal del seno coronario. En la mayoría de corazones humanos hemos observado una válvula parcial asociada a este ostium cuando ingresa al seno coronario.

Función:
Esta vena cardíaca devuelve sangre desoxigenada (productos de desecho metabólico) de la pared lateral del ventrículo izquierdo.

Importancia en implante de dispositivos:
La estimulación del corazón izquierdo se puede lograr a través de la implantación de electrodos en esta vena; a menudo se intentará acceder a ramas más posterolaterales.
