Detection of late arrhythmia and conduction disturbance after correction of tetralogy of Fallot.
Why the study?
Are progressive conduction defects associated with late sudden death, complete heart block, or ventricular arrhythmias in patients after correction of tetralogy of Fallot?
Population
196 patients who underwent correction of tetralogy of Fallot
Design
Cohort
Follow-up
1 to 20 years (mean 10)

Implication
May warrant enhanced post-TOF arrhythmia surveillance; leaves open links to sudden death prevention.

Outcome
Late sudden death, complete heart block, and ventricular arrhythmiashard clinical
Progressive conduction defects after tetralogy of Fallot correction are associated with a significantly higher incidence of ventricular arrhythmias, highlighting the need for monitoring to identify patients at risk for sudden death.
