Tetralogy of Fallot

Tetralogy of Fallot is the most common cyanotic congenital heart defect. Outcomes with surgical repair have improved over the years, leading to a growing number of adults with surgically repaired Tetralogy of Fallot. Nevertheless, residual cardiac abnormalities are common in these patients and thus they require life-long imaging surveillance. Cardiovascular magnetic resonance (CMR) is well suited for this task because of its ability to accurately measure biventricular size and function, quantify valve regurgitation, image the thoracic vasculature, and identify myocardial fibrosis. Information from CMR now guides decisions regarding pulmonary valve replacement and contributes to risk stratification for adverse cardiac events.
