Key result
Echocardiography and phonocardiography of the Lillehei-Kaster mitral valve prosthesis demonstrated a disc excursion of 7-12 mm, mean opening velocity of 37.7 cm/sec, and a two-fold closing sound.
Observational (n=22)
Establishing the normal echocardiographic and phonocardiographic profile of the Lillehei-Kaster mitral valve prosthesis aids in the noninvasive evaluation of its function and the detection of complications.

Normal L-K mitral prosthesis shows stenosis-like ECHO with defined velocities; leaves open differentiation from dysfunction.
Gibson et al. (1974) conducted an observational in Lillehei-Kaster mitral valve prosthesis (n=22). Echocardiography and phonocardiography of Lillehei-Kaster mitral valve prosthesis was evaluated on Echocardiographic and phonocardiographic characteristics (disc excursion, opening/closing velocity, timing of sounds). Echocardiography and phonocardiography of the Lillehei-Kaster mitral valve prosthesis demonstrated a disc excursion of 7-12 mm, mean opening velocity of 37.7 cm/sec, and a two-fold closing sound.
