RBBB-LAH after tetralogy of Fallot repair was associated with higher late mortality and complete heart block; leaves open whether prophylactic pacing improves outcomes.
Does the development of RBBB-LAH following surgical repair of tetralogy of Fallot increase the risk of morbidity and mortality?
The development of RBBB-LAH after tetralogy of Fallot repair is associated with a significantly increased risk of complete heart block, serious ventricular arrhythmias, and late mortality, suggesting a potential need for prophylactic pacing.
