Introduction. The concept of ventricular anatomy as a single muscular band was initially described by Francisco Torrent-Guasp in 1972 1 and since then, there have been multiple novel contributions to the understanding of the morphology and function of the heart. To date, this concept has been supported and denied by multiple groups of professionals reflecting both the enthusiasm and resistance to the new concept of the single muscle band model. Currently, the single muscular band is the model that meets all the requirements to explain the performance of cardiac mechanics, and its distinctive feature to determine the characteristics of the structure.
