Abstract

The indications for using temporary epicardial pacing wires after pediatric cardiac surgery remain unclear. Post-procedure intracardiac pressure is valuable for detecting circulatory disturbances and residual lesions. This study aimed to examine the association between post-procedure intracardiac pressures and the use of temporary epicardial pacing wires. We performed a retrospective, case–control study at the pediatric intensive care unit of an urban regional tertiary hospital that included patients who had undergone congenital heart surgery between January 2015 and December 2016. We measured post-procedure intracardiac pressures, and data regarding baseline characteristics, procedures performed, and intraoperative variables were collected as covariates. Of the 186 included patients, 34 (18.3%) were treated using temporary epicardial pacing wires. The optimal cutoff values used to predict the use of pacing wires for central venous pressure, left atrial pressure, pulmonary arterial pressure/systemic blood pressure ratio, and right ventricular pressure/left ventricular pressure ratio were 11 mmHg (55.6% sensitivity, 86.2% specificity), 13 mmHg (50% sensitivity, 84.6% specificity), 0.39 (69.6% sensitivity, 78.7% specificity), and 0.51 (74.1% sensitivity, 64.2% specificity), respectively. Multivariable logistic regression analyses showed that the use of temporary epicardial pacing wires was significantly associated with left atrial pressure ≥ 11 mmHg (odds ratio 4.4; 95% confidence interval 1.01–18.9), and a pulmonary arterial pressure/systemic blood pressure ratio ≥ 0.39 (odds ratio 6.3; 95% confidence interval 1.3–31.4). High post-procedure intracardiac pressures were associated with the use of temporary epicardial pacing wires. These data can aid in the decision-making for the proper use of temporary epicardial pacing wires.
