Questions band-based models in surgery; leaves open validation of helical mass architecture in outcomes research.

Key Points

To review anatomical evidence regarding the arrangement of ventricular myocytes and assess the validity of the ventricular myocardial band hypothesis compared with a continuous syncytial model.
Synthesized findings from anatomical and morphological evaluations conducted independently and collaboratively over a period spanning nearly 30 years.
Examined myocardial structural organization, connective tissue matrices (epimysium, perimysium, endomysium), and the boundaries of putative ventricular muscle bundles.
No anatomic evidence of discrete muscle bundles possessing separate origins, insertions, or dividing fibrous sheaths was observed to support the ventricular myocardial band concept.
Myocytes are arranged within a continuous, interconnected three-dimensional mass supported by a collagenous matrix with a pervasive helical orientation that accounts for ventricular twisting during contraction.
