Echocardiography has the following attributes:

  • Color-flow Doppler echocardiography: Assesses overall cardiac function and the status of the valves, and for the presence of any residual VSD, ductus arterosus, or atrial septal defect

  • Allows evaluation of the valvular anatomy but is unable to visualize the coronary anatomy in adults

  • Reveals the grade and severity of any RVOT obstruction
