Ventricular-Arterial Coupling in Children and Infants With Congenital Heart Disease After Cardiopulmonary Bypass Surgery: Observational Study*

Conclusions: Median ventricular-arterial coupling values in children after cardiac surgery appear high (above 1). Uncoupling was particularly evident in high ventricular-arterial coupling patients who showed the lowest end-systolic elastance values (but not significantly different arterial elastance values) compared with low ventricular-arterial coupling. Ventricular-arterial coupling appears to be inversely proportional to pre-ejection time, total ejection time, and ejection fraction.
