Tetralogy of Fallot (TOF) is a common congenital disorder which is treated by surgical repair. This study aimed to investigate alterations in blood flow in adults with repaired TOF. We hypothesized that abnormal remodeling of the right heart and the PA following surgical repair leads to impaired blood flow distribution, increased wall shear stress (WSS), greater energy loss (EL) and greater pressure drop (PD) in rTOF adults. This study contributes towards the understanding of blood flow hemodynamics after surgical repair.
