A new finger-type epicardial echocardiographic probe was evaluated in 26
children with complex cardiac anomalies during open heart surgery. The
probe is a small 3.75 MHz phased array transducer for 2-dimensional echo
and color Doppler imaging. The tip is slightly angled to facilitate the
apical approach through a median sternotomy. The patients included 4
neonates and 8 infants, and the major cardiac lesions were complete
atrioventricular (AV) canal, transposition of the great arteries, double
outlet right ventricle, and others. The intraoperative study was possible
in most of the patients facilitating various approaches for the assessment
of left-sided AV valve function, left ventricular outflow obstruction,
residual shunt and intraatrial anatomy. Four patients received subsequent
operative procedures after the assessment. This transducer appears to be
useful in the intraoperative study during surgery for complex cardiac
anomalies in neonates and small infants.
