Technical Performance Score: Predictor of Outcomes in Complete Atrioventricular Septal Defect Repair.
Annals of Thoracic Surgery 2017 October
BACKGROUND: Technical performance score (TPS) has been associated with both early and late outcomes across a wide range of congenital cardiac procedures. We sought to validate TPS as predictor of outcomes for complete atrioventricular septal defect (CAVSD) repair.
METHODS: This was a single-center retrospective review of patients after balanced CAVSD repair between January 1, 2000, and March 1, 2016. We assigned TPS (class 1, no residua; class 2, minor residua; class 3, major residua or reintervention before discharge for residua) based on summation of subcomponent scores from discharge echocardiograms. Outcomes of interest were in-hospital complications, postoperative days on ventilator, and postdischarge reintervention.
RESULTS: Among 350 patients, median age was 3.2 months (interquartile range [IQR], 2.4 to 4.2 months). Fifty-four patients (16%) had class 1 TPS, 218 (62%) class 2, 63 (18%) class 3, and 15 (4%) were unscorable. There were 36 complications (10%), and median postoperative days on ventilator were 2 (IQR, 1 to 3) days. There were 34 postdischarge reinterventions (10%). Median follow-up was 2.6 years (IQR, 0.09 to 7.9) years. On multivariable modeling, class 3 TPS was associated with complications (odds ratio 5.45, 95% confidence interval [CI]: 1.06 to 28.1, p = 0.04), prolonged postoperative ventilator days (hazard ratio [HR] 0.54, 95% CI: 0.37 to 0.80, p = 0.002), and postdischarge reintervention (HR 5.61, 95% CI: 1.28 to 24.5, p = 0.02) after adjusting for covariates such as age, weight, genetic abnormality, concomitant procedure, prematurity, and second bypass run.
CONCLUSIONS: At our center, CAVSD repair was associated with low morbidity. TPS may identify patients with complications, prolonged days on ventilator, and who require postdischarge reinterventions; thus, it provides feedback on areas of improvement and allows identification of patients who warrant closer follow-up.
