Identifies high-risk subgroups after tetralogy of Fallot repair; leaves open whether targeted interventions reduce sudden death.
What is the risk of sudden death associated with postoperative conduction disturbances in patients following total correction of tetralogy of Fallot?
Patients with right bundle branch block and premature ventricular contractions, or trifascicular block, following tetralogy of Fallot repair have a high risk of sudden death, warranting careful long-term follow-up and consideration of suppressive therapy.
