title: On the explanation of the M-mode echocardiographic image of an atrial myxoma.
abstract: Two experimental models were used to simulate the motion of a valve leaflet and atrial myxoma in order to investigate the echocardiographic images produced. Both support the view that an endogenous contrast effect, i.e. surfaces of different acoustic densities that are produced as a result of turbulence in a fluid medium and give rise to echo images, contributes to the echocardiographic M-mode appearance of the atrial mass.
