This subcostal long axis view of the right ventricle (RV) demonstrates the anterior deviation of the outlet septum (*), causing the infundibular pulmonary stenosis associated with tetralogy of Fallot. There is also supravalvar pulmonary stenosis with dilatation of the pulmonary trunk (PT). The aorta (A) overrides the interventricular septum in this heart with an atrioventricular septal defect (not shown). (SCV-superior caval vein, RA-right atrium)

A deeper cut into the right ventricle (RV) of the heart shown in TOF1a, shows the common atrioventricular valve (AVV). The left (L) component of the common atrioventricular valve is most posterior, the anterior portion resected and demonstrating the inferior (IBL) and superior (SBL) bridging leaflets as they cross the crest of the interventricular septum (yellow dots). The aorta (A) overrides the interventricular septum and the outlet septum is deviated anteriorly causing the infundibular pulmonary stenosis characteristic of tetralogy of Fallot. Please note the fibrous continuity between the aortic valve and the superior bridging leaflet
