Double-Outlet Right Ventricle Fallot Type Versus Tetralogy of Fallot: Comparison of Native Anatomy, Surgical Patterns, and Outcomes

Background: The conotruncal anomalies double-outlet right ventricle Fallot type (DORV TOF) and tetralogy of Fallot (TOF) show similar characteristics such as hemodynamics and repair techniques. However, estimates of survival and morbidity of this morphological TOF subgroup are currently scarce. We sought to describe native anatomy, surgical patterns and outcomes in patients with DORV TOF in comparison to classic TOF.
