CMRI is useful for quantification of ventricular size and function, pulmonary valve function, pulmonary artery (PA) anatomy, and left heart abnormalities in patients with repaired tetralogy of Fallot.

Obtain coronary artery compression testing before performing right ventricle-to-PA conduit stenting or transcatheter valve placement in repaired tetralogy of Fallot.

Programmed ventricular stimulation can be useful for risk stratification of adults with tetralogy of Fallot and additional risk factors for sudden cardiac death (SCD).

In patients with repaired tetralogy of Fallot, cardiac catheterization with angiography, if indicated, is reasonable to assess hemodynamics when adequate data cannot be obtained noninvasively in the setting of an arrhythmia, heart failure, unexplained ventricular dysfunction, suspected pulmonary hypertension, or cyanosis.
