Abstract

OBJECTIVES: The technical performance score (TPS) has been reported in a single center study to predict the outcomes after congenital cardiac surgery. We sought to determine the association of the TPS with outcomes in patients undergoing the Norwood procedure in the Single Ventricle Reconstruction trial.

METHODS: We calculated the TPS (class 1, optimal; class 2, adequate; class 3, inadequate) according to the predischarge echocardiograms analyzed in a core laboratory and unplanned reinterventions that occurred before discharge from the Norwood hospitalization. Multivariable regression examined the association of the TPS with interval to first extubation, Norwood length of stay, death or transplantation, unplanned postdischarge reinterventions, and neurodevelopment at 14 months old.

RESULTS: Of 549 patients undergoing a Norwood procedure, 356 (65%) had an echocardiogram adequate to assess atrial septal restriction or arch obstruction or an unplanned reintervention, enabling calculation of the TPS. On multivariable regression, adjusting for preoperative variables, a better TPS was an independent predictor of a shorter interval to first extubation (P=.019), better transplant-free survival before Norwood discharge (P

CONCLUSIONS: TPS is an independent predictor of important outcomes after Norwood and could serve as a tool for quality improvement.
