Why the study?
Arrhythmias can develop after successful operative repair of TOF, but the relationship between arrhythmias and right ventricular dilatation is not established.
Is increased right ventricular end diastolic volume index (≥ 150 ml/m2) associated with a higher incidence of arrhythmias in pediatric and adolescent patients after successful Tetralogy of Fallot repair?
Is increased right ventricular end diastolic volume index (≥ 150 ml/m2) associated with a higher incidence of arrhythmias in pediatric and adolescent patients after successful Tetralogy of Fallot repair?
In pediatric and adolescent patients after successful Tetralogy of Fallot repair, arrhythmias were significantly associated with increased postoperative duration but not with pulmonary regurgitation fraction or right ventricular end-diastolic volume index.

Arrhythmias post-TOF repair linked to longer follow-up but not RVEDVI or PR; leaves open need for prospective arrhythmia predictors.
