Older age at tetralogy of Fallot repair was associated with higher late sudden death risk; leaves open whether earlier repair reduces arrhythmia burden.
What are the risk factors and electrocardiographic findings associated with late sudden death in survivors of tetralogy of Fallot repair?
Older age at the time of tetralogy of Fallot repair is associated with an increased risk of late sudden death and frequent ventricular arrhythmias in long-term survivors.
Jonsson et al. (1995) studied this question.
