Color-flow echocardiography is always obtained in adult patients tetralogy of Fallot to assess the overall cardiac function and the status of the valves, and for the presence of any residual ventricular septal defect (VSD), ductus arterosus, or atrial septal defect. Note that although echocardiography can assess the valvular anatomy, it is unable to visualize the coronary anatomy in the adult patient. This imaging modality is also able to reveal the grade and severity of any RV outflow tract (RVOT) obstruction.
