Tricuspid regurgitation in patients with repaired tetralogy of Fallot is an important finding with a wide spectrum of primary and secondary etiologies. Moderate or severe tricuspid regurgitation is associated with a greater incidence of atrial tachyarrhythmias in these patients. It remains uncertain which patients with repaired tetralogy of Fallot may benefit from a tricuspid valve intervention at the time of pulmonary valve replacement.
