The string-like structures that anchor the valve flaps of the AV valve are called the chordae tendinae, which attach to the papillary muscles of the ventricles. Interestingly enough, the bundle branches extend down and into the areas where the papillary muscles are located, and the resulting contraction of the ventricles ensures that the papillary muscles pull the valves tight, ensuring that they are closed thoroughly to prevent backflow in the heart.
