Use of extracorporeal life support in total anomalous pulmonary venous drainage.

Abstract

The diagnosis of TAPVD was often known before the initiation of ECLS. Neonates were more likely to survive if the repair could be done before or after ECLS rather than during ECLS. The lower survival of infants who underwent repair during ECLS reflects the degree of illness in many of these infants who were placed on ECLS on an emergency basis because their condition was too unstable to permit detailed cardiac evaluation. The survival rate of infants with TAPVD requiring ECLS is poor, with approximately one half of the survivors having mental and motor deficiencies; however, these infants represent a subset of patients with TAPVD who probably would have died without ECLS. We recommend that infants who are not starting to wean from ECLS at 7 days undergo reevaluation with color-flow Doppler echocardiography with consideration for cardiac catheterization if the diagnosis is in doubt. We also recommend that before infants with known TAPVD are placed on ECLS parents should be informed that survival with the use of ECLS is no different from survival with operation alone and that many of the survivors are impaired. Each active ECLS center should periodically review its accuracy in making this definitive diagnosis.
