Single Ventricle and Total Anomalous Pulmonary Venous Connection: Implications of Prenatal Diagnosis:

Background:Single ventricle (SV) patients with total anomalous pulmonary venous connection (TAPVC) are at high risk. Given the limited published data available, we examined outcomes and the implications of a prenatal diagnosis of SV/TAPVC.Methods:A single-center, retrospective review was performed in neonates with SV/TAPVC from 1998 to 2014, identified through institutional databases. Patient demographic, perioperative, and follow-up data were collected.Results:Thirty-four eligible infants with SV/TAPVC were identified (mean birth weight: 3.0 kg). The TAPVC types were supracardiac (59%), infracardiac (21%), mixed (12%), and cardiac (9%). Heterotaxy syndrome was present in 25 (74%) infants. A prenatal diagnosis of SV was made in 26 (76%) infants, with TAPVC identified in 12 (35%). Seventeen (50%) had obstructed TAPVC within the first 48 hours of life; 7 of these patients had obstructed TAPVC identified prenatally. There were two preoperative deaths. Overall survival for the cohort was 65% at 1 year and 50%...
