Implication

This review summarizes current challenges and emerging strategies in the long-term management of repaired Tetralogy of Fallot, including imaging, arrhythmia risk stratification, and pulmonary valve replacement.

Key Points

To synthesize emerging scientific concepts and clinical strategies for optimizing the long-term management of patients with repaired tetralogy of Fallot.
Reviewed scientific literature regarding genetic etiology, cardiac magnetic resonance imaging capabilities, and risk factors for post-repair morbidity in tetralogy of Fallot.
Evaluated clinical efficacy and limitations of pharmacological therapies, transcatheter interventions, implantable defibrillators, and surgical pulmonary valve replacement.
Familial recurrence risk for tetralogy of Fallot is 3%, and cardiac magnetic resonance serves as the gold standard for quantifying right ventricular volume, function, and pulmonary regurgitation.
Arrhythmia burdens are substantial, with atrial re-entrant tachycardia occurring in >30% of repaired patients, high-grade ventricular arrhythmias in ~10%, and sudden cardiac death at an estimated rate of 0.2%/yr.
Medical therapy for right ventricular dysfunction remains ineffective except for biventricular pacing, while criteria for transcatheter valve insertion and pulmonary valve replacement timing continue to evolve.

Villafañe et al. (2013) conducted a review in Tetralogy of Fallot. Tetralogy of Fallot management relies on cardiac magnetic resonance for assessment, while optimal surgical strategies and timing for pulmonary valve replacement remain uncertain.
