Survival After Norwood Procedure in High Risk Patients

Purpose: Historical studies have identified multiple single ventricle populations at increased risk for mortality following the Norwood Procedure. These pre-operative risk factors include low birth weight (LBW), restrictive or intact atrial septum or obstructed pulmonary veins, ventricular dysfunction and atrioventricular (AV) valve regurgitation. Data is lacking on longer term outcomes for these high risk populations and it remains unclear whether contemporary survival in these groups has improved along with overall Norwood survival. We sought to report outcomes of the Norwood procedure in high risk patients …
