This parasternal long axis view demonstrates anterior malalignment of the conal septum (CS) when compared with the plane of the trabecular septum (IVS), resulting in aortic override and subpulmonary stenosis in this patient with tetralogy of Fallot.
VSD: ventricular septal defect; RV: right ventricle; LV: left ventricle; AO: aorta; LA: left atrium; CS: conal septum; IVS: trabecular portion of interventricular septum; arrow: VSD.
