3.4 Residual malformations
Residual cardiac malformations were found in 6 cases by transthoracic
echocardiography. One neonate’s malformation was corrected during ECMO
and discharged. Other patients were weaned successfully, but died
finally due to recurrent heart failure. There was a statistically
significant difference between the survival and non-survivals (P =
0.04). Studies [19,20] have reported that
one-quarter of children with ECMO support after open open-heart surgery
have residual anatomical problems. All residual lesions should be
evaluated actively, early examination and interventional therapy were
related to better clinical outcomes. Therefore, residual malformations
should be discovered as soon as possible, and active intervention can
improve cardiac function.
