Late gadolinium enhancement imaging in the ventricular short-axis showing intense late hyperenhancement in the RVOT (white arrow) and weak hyperenhancement in the superior and inferior junctions between the interventricular septum and the free wall (yellow arrows). The former represents scar tissue and is associated with regional wall motion abnormalities. The latter is a commonly observed finding in patients with repaired TOF and its clinical importance is uncertain [42, 85].
