Tetralogy of Fallot

Abstract

Fallot’s tetralogy is characterized by its outflow tract morphology. The pulmonary infundibular tract is narrowed due to an anteriorly displaced outlet septum, thereby contributing to a large malalignment ventricular septal defect and right ventricular override of the aortic valve [12]. The ventricular septal defect in Fallot’s tetralogy is almost always of the outlet type (Fig. 4.1) and is perimembranous in nature in approximately 75% of cases (Fig. 4.1). The degree of override of the aortic valve may vary considerably; in some instances almost all of the aortic orifice is positioned over the right ventricle.
