Ag. Rodrigues et al., TRANSTHORACIC ECHOCARDIOGRAPHIC ASSESSMENT OF PERIPROSTHETIC MITRAL REGURGITATION USING INTRAVENOUS-INJECTION OF SONICATED ALBUMIN, The American journal of cardiology, 79(6), 1997, pp. 829
Mechanical prostheses induce artifacts that decrease the accuracy of c
onventional transthoracic echocardiographic imaging for the detection
and quantitation of periprosthetic mitral regurgitation. In 15 patient
s undergoing transthoracic echocardiography, injection of sonicated al
bumin significantly enhanced the assessment of periprosthetic mitral r
egurgitation with an accuracy similar to that of transesophageal echoc
ardiography.
