Bar plots showing the longitudinal (ε
) and circumferential (ε
strain values in a pediatric population with systemic single ventricles. We demonstrate a significant reduction in both εL and εcc. The septum is the most affected with negligible differences observed in the free wall. Also, there is a significant difference observed from apex to base globally for both the single systemic ventricle patients, while the free wall εL shows a significant increase.
