[Dynamic intracavitary echoes from non-slow flow in a patient with a mitral prosthesis].

: The infrequent finding of visualization of circulating blood by two-dimensional echocardiography in the left ventricle in a patient with a mitral prosthetic valve is reported. In contrast to most of the reports on dynamic intracavitary echoes, no correlation with blood stasis or diminished flow velocity is found, being normal in this pulsed Doppler study.
