Detailed left bundle branch anatomy in normal hearts may inform conduction disorder interpretation; leaves open clinical correlation in prospective cohorts.
Observational (n=13)
This morphological study clarifies the detailed anatomical distribution of the left bundle branch in the normal human heart, including the consistent presence of an extremely anterior fascicle.
Sakaguchi et al. (1988) conducted an observational in Normal human heart (n=13). Morphological examination of 13 autopsied normal human hearts revealed that the left bundle branch bifurcates into anterior and posterior radiations, with an extremely anterior fascicle in all cases.
