title: Induction of Papillary Growths in the Heart.
abstract: Papillary growths appeared on the atrial endocardium of dogs at sites where adjacent surfaces presumably came into contact with a reciprocating motion. It is suggested that the resulting friction stimulates the growth of papillae which then act as pedunculated ballbearings, reducing the friction.
