Summary The incidence, distribution, and macro‐ and microscopic structures of left ventricular false tendons ( LVFT s) in the cat heart were studied using 25 normal and 57 diseased hearts. The fibrous bands were observed in the left ventricle of all 82 cat hearts examined and most commonly extended between the papillary muscles and the ventricular septum. Histologically, the LVFT s were composed of central Purkinje fibres and surrounding dense collagenous fibres covered by endothelium. There was no appreciable difference in the incidence, distribution or morphology of LVFT s between the normal and the diseased hearts, indicating that LVFT s are a common anatomic variant in the cat heart.
