Myocardial Fiber Architecture in the Human Heart
TLDR
Ventricular myocardial fiber architecture has been considered an important factor in heart dynamics but most anatomical studies however have focussed on the analysis of normal hearts.Abstract:

Ventricular myoarchitecture in tetralogy of Fallot.
TL;DR: The malformed hearts showed modifications in ventricular shape, in the arrangement of muscle in the right ventricle, and in the overall myoarchitecture, which could well be the consequence of the same agent (or agents) that caused the structural defect.
Journal ArticleDOI
The anatomical arrangement of the myocardial cells making up the ventricular mass.
TL;DR: A review of the anatomical studies performed separately and conjointly over a period of nearly 30 years shows that there is no anatomic evidence to support the concept of a 'ventricular myocardial band', and the overall arrangement is for the myocytes to be supported as the muscular components of a continuous and complex mass.
Journal ArticleDOI
Regional localisation of left ventricular sheet structure: integration with current models of cardiac fibre, sheet and band structure.
TL;DR: Evidence points to significant inter-individual structural variability in the canine, leading to the concept of a continuum (or distribution) of cardiac structures, which partly explains the ongoing debate on myocardial architecture.
Journal ArticleDOI
The three‐dimensional arrangement of the myocytes in the ventricular walls
TL;DR: Investigations show that the only muscular unit to be found within the myocardial walls is the cardiac myocyte itself, and that, rather than forming a continuous band, or being arranged as sheets, the myocytes are aggregated together as a three‐dimensional mesh within a supporting matrix of fibrous tissue.
Journal ArticleDOI
Three-dimensional cartography of the pattern of the myofibres in the second trimester fetal human heart.
TL;DR: The findings show that the fibre architecture of the heart can be conceptualised as myocardial fibres running like geodesics on a nested set of warped ”pretzels”, and that this model is the only existing model that explains the observed rolling over of fibres around the atrioventricular valvar orifices.
