Background: We have shown previously that technical performance score (TPS) is associated with post-discharge (DC) reinterventions (RI) in patients who undergo complete atrio ventricular septal defect (CAVSD) repair. The aim of this study is to determine which subcomponents of TPS can best predict post-DC RI.
Methods: Patients who underwent CAVSD repair between 2000 and 2016 were included. The final TPS (class 1-no residua, class 2-minor residua, class 3-major residua or RI pre-DC for residua) were assigned based on the summation of the subcomponent score for DC echocardiograms and certain clinical criteria as previously described. Follow-up (FU) data for up to 16 years were retrospectively collected. Nonparametric methods were used to determine association between the subcomponents of TPS and post-DC RI.
Results: A total of 331 patients were included in the analysis. There were 211 (60%) females. Median age at surgery was 3.2 (IQR: 2.4, 4.2) months. Fifty-four (16%) had class 1 TPS, 217 (66%) Class 2, 60 (18%) Class 3. There were 34 (10%) post-DC RI. Median FU was 2.6 (IQR: 0.09, 7.9) years. On nonparametric analysis, left atrioventricular valve (AVV) regurgitation, right AVV regurgitation and abnormal conduction were strongly associated with post-DC RI.
Conclusions: Pre-DC left and right AVV regurgitation and abnormal conduction at DC are among the subcomponents that are strongly associated with post-DC RI following CAVSD repair. TPS can serve as important tool for identifying patients at risk for RI.
