Two-dimensional transesophageal color Doppler echocardiography was employed
intraoperatively in 30 children undergoing repair of a variety of simple
and complex cardiac malformations. There were 16 female and 14 male
patients, with a mean age of 9 +/- 3 years (range, 4 to 13 years) and a
mean weight of 31 +/- 9 kg (range, 16 to 50 kg), 16 children weighing less
than 30 kg. A standard, commercially available transesophageal
echocardiography probe (5 MHz, 64 elements) was used in all patients
without complications. Transesophageal echocardiography proved helpful in
selecting the surgical approach, in assessing the adequacy of surgical
repair, in detecting residual intracardiac shunts, and in allowing
uninterrupted monitoring of ventricular performance throughout the
procedure. Our initial experience suggests that transesophageal
echocardiography is a valuable tool to be used in children with congenital
cardiac malformations, particularly in those requiring complex intracardiac
procedures. The amount of information obtained by the surgeon should favor
the routine use of transesophageal echocardiography during open heart
procedures and stimulate the development of probes to be safely used even
in infants and newborns.
