Abstract The double-root translocation (DRT) procedure is considered as a new choice for surgical management of complex congenital heart disease. Our study aims to investigate the left ventricular hemodynamic status after DRT by energy loss (EL), involving 42 patients who underwent DRT as well as 42 healthy volunteers as controls. The EL of left ventricle (LV) during different periods (rapid filling-RF, atrial contraction-AC, isovolumic contraction-IVC, rapid ejection-RE) of the same cardiac cycle were obtained and analyzed. Compared to the controls, global LV and apical three chamber-EL at AC and IVC periods in DRT group were higher (p
