General Structure of the Cardiac Wall

 

The Cardiac Fibrous Skeleton

  1. To ensure electrophysiological discontinuity between the atria and ventricles (only connection is via the atrioventricular bundle).
  2. To provide mechanical attachment for the atrial and ventricular muscles.
  3. To maintain the cardiac position within the pericardium.
  4. To provide a stable but deformable base for the valvular fibrous cores.
