Characterization of the Septal Discontinuity in Ex-Vivo Human Hearts Using Diffusion Tensor Imaging: The Potential Structural Determinism Played by Fiber Orientation in Clinical Phenotype of Laminopathy Patients.

A key component of the cardiac conduction system is the atrioventricular (AV) node where the His bundle (HB) divides into the right (RBB) and left (LBB) bundles branches. The RBB is connected to the right ventricle (RV) via the moderator band (MB).
