Implication

Clinical review evaluates outcomes of pulmonary valve replacement in repaired tetralogy of Fallot, highlighting optimal timing to preserve right ventricular function.

Key Points

Evaluate indications, clinical timing, and procedural outcomes of pulmonary valve replacement in patients with late pulmonary regurgitation following initial repair of tetralogy of Fallot.
Assesses surgical and transcatheter approaches to pulmonary valve replacement after repair of tetralogy of Fallot.
Evaluates hemodynamic indices, right ventricular volume thresholds, and functional clinical endpoints.
Pulmonary valve replacement successfully relieves chronic pulmonary regurgitation and reduces right ventricular volume overload.
Early intervention prior to irreversible right ventricular remodeling is associated with superior functional recovery and reduced arrhythmia risk.

Cavalcanti et al. (2013) conducted a meta-analysis in Repaired tetralogy of Fallot with pulmonary insufficiency (n=3,118). Pulmonary valve replacement was evaluated on 30-day mortality. Pulmonary valve replacement in patients with repaired tetralogy of Fallot improved biventricular function and symptoms, with a pooled 30-day mortality of 0.87% and 5-year mortality of 2.2%.
