Reproducibility of Cardiac Magnetic Resonance Imaging (CMRI)-Derived Right Ventricular Parameters in Repaired Tetralogy of Fallot (ToF)

In patients with repaired ToF and variable degrees of RV dilatation, CMR assessment of RV volumes and function has high inter-observer reproducibility. This allows for optimal timing of pulmonary valve replacement, based on progression of RV dilatation over time.
