The function of the heart corresponds to a mechanical dimension that should be addressed in terms of its structure, which is where we find the origin of the idea that led our research to explain its organic-functional integrity. The real internal myocardial anatomy, and contrary to the classical concept, dissection finds a structure with defined planes that allows successive and concatenated physiological motions of narrowing, shortening-twisting, lengthening-untwisting and expansion. Faced with this mechanics, myocardial torsion represents the functional solution to eject the ventricular blood content with the necessary energy to supply the whole organism. The inevitable emerging question is that in order for the muscular bands surrounding the ventricles to twist they should have a supporting point, similarly to a muscle in a rigid insertion.
