Single Ventricle Palliation in Low Weight Patients Is Associated With Worse Early And Midterm Outcomes

Low weight at time of first-stage SV palliation is associated with an increase in both hospital mortality and interstage attrition, with subsequently fewer patients progressing toward the Glenn operation. The increased death hazard in low weight SV patients persists for almost 1 year after initial palliation, suggesting the need for more vigilant monitoring and out-patient care in those high-risk patients.
