AMERICAN ASSOCIATION FOR THORACIC SURGERYbetween groups: 97% (38/39) in high-risk versus 97% (119/123) in standard-risk.Survival to stage 2 palliation was 87.2% (34/39) in high-risk versus 93.5% (115/123)in low risk groups, p = 0.2. High-risk patients discharged from ICU were morelikely to require inpatient treatment until stage 2 palliation: 26% (9/34) versus 10%(12/118), p = 0.003, although age at stage 2 palliation was not different (126 ± 33days versus 116 ± 38 days, p = 0.2). High-risk patients had lower 1 year survival(76% versus 93%, p = 0.001) and survival to date (72% versus 92%, p = 0.004).CONCLUSION: With an intensive monitoring strategy, identical high early survivalwas achieved in both patient risk strata. Prolonged interstage hospitalizationfor intensive non-invasive monitoring in high-risk patients until stage 2 palliationconferred similar survival to standard-risk patients monitored at home. Mortalitybeyond stage 2 palliation when level of monitoring is reduced is a relatively uniquefeature of high risk patients. Although mortality is reduced with enhanced monitoring,high resource utilization and late attrition of high-risk patients after stage 2palliation suggests an ongoing need to evaluate our current palliative strategy for asubset of patients with univentricular heart disease.5:00 p.m. EXECUTIVE SESSION(AATS Members Only)Ballroom A–C, Hynes Convention CenterTUESDAYAfternoon195
