Risk calculators and risk factors for Tetralogy of fallot echocardiography

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editors-In-Chief: Priyamvada Singh, M.B.B.S. [2], Keri Shafer, M.D. [3]; Assistant Editor-In-Chief: Kristin Feeney, B.S. [4]


Echocardiography establishes the initial diagnosis of tetralogy of Fallot, and is useful in evaluating the hemodynamic abnormalities that are present. Right-to-left shunting through the VSD can be visualized by color doppler imaging, and the severity of right ventricular outflow tract obstruction can be determined by spectral doppler measurements. Echocardiography may be helpful in the diagnosis of tetralogy of fallot. Findings on an echocardiography diagnostic of tetralogy of fallot include ventricular septal defect, right ventricular outflow tract obstruction, and overriding aorta.


Echocardiography may be helpful in the diagnosis of tetralogy of fallot. Findings on an echocardiography diagnostic of tetralogy of fallot include:

Optimal Views

  • Parasternal long-axis view
  • Short-axis view (to evaluate size of septal defect)

Post-operative Evaluation
