POSTERIOR INTERVENTRICULAR SULCUS

Author: Dr. Jonathan Hayes Published: February 19, 2026 Access: Public

The posterior interventricular sulcus is a crucial anatomical feature located within the heart. It serves as a pathway for important structures, playing a vital role in the heart's function and overall health. This sulcus is a deep groove that runs along the surface of the heart, connecting the right ventricle to the left atrium. Its primary purpose is to provide a route for the coronary sinus, which is a critical component of the heart's venous drainage system.
