Morphologic study of left ventricular bands.
The presence of left ventricular bands has drawn attention to their possible clinical importance, though there are no concrete data to support their role in serious clinical diseases. We have investigated the incidence, location, microscopic and macroscopic structure of left ventricular bands in the human and animals. We examined 100 hearts: 28 human and 72 animal (dog, goat, sheep). Left ventricular bands were present in 13 of 28 (46%) human hearts and 62 of 72 (86%) animal hearts. The bands usually extended from the interventricular septum to the free walls in human hearts and from the papillary muscles to the interventricular septum in animal hearts. They were composed of muscle tissue in various proportions in human and dog hearts, and of connective and conductive tissue in sheep and goat hearts.
