“…Most of these predictors correlated to the risk of atrial fibrillation rather than AFL/IART, which is more likely to be pertinent in a TOF population. QRSd, as demonstrated in various TOF cohorts, is a univariate predictor of atrial arrhythmias; whereas P‐R prolongation has also been shown to be a univariate predictor of atrial arrhythmias in TOF patients late after repair …”

“…Bonello et al 10 have previously described the morphological and haemodynamic characteristics of tetralogy of Fallot patients with atrial arrhythmias; of 154 patients, atrial tachyarrhythmias – sustained atrial tachyarrhythmias or atrial fibrillation – were observed in 11, a slightly lower incidence than has previously been reported, and were predicted by right atrial area on cardiac magnetic resonance imaging. Another study 11 examined the echocardiographic profiles of tetralogy of Fallot patients with palpitations but no documented tachycardia and also noted that the only significant difference in echocardiographic parameters between those with and without a history of palpitations was right atrial size. Our study in contrast highlights that atrial tachyarrhythmias are not only associated with right atrial enlargement but also with an increase in left atrial size.…”

Patients with tetralogy of Fallot and atrial tachyarrhythmias have more dilated atria than those without atrial tachyarrhythmias. Radiofrequency ablation improves functional status. Left atrial ablation is more commonly required with repeat procedures. There is a high prevalence of atrial tachyarrhythmias, particularly atrial fibrillation, in patients with tetralogy of Fallot; early radiofrequency ablation may have a protective effect against this.

SummaryTetralogy of Fallot (TOF) is the most common cause of cyanotic congenital heart defect. Over the last century, the life expectancy of TOF patients has significantly improved. This, however, has brought new challenges both to patients and their health-care providers, the main of them being late arrhythmia. Ironically, late arrhythmia is predominantly generated due to the fibrotic scars caused by the life-saving surgical repair. Once the first two mainly arrhythmia-free decades after the repair pass, the risk of developing late arrhythmia and, therefore, SCD becomes substantial. Consequently, young adults with repaired Tetralogy of Fallot (rTOF) require careful outpatient monitoring.There have been many attempts to predict the risk of life-threatening arrhythmia in rTOF patients. This has led to the defining of various risk factors, ranging from the widely used QRS prolongation to novel predictors, derived from cardiac magnetic resonance (CMR) based anatomical findings (left ventricular dyssynchrony indexes, right ventricular output tract akinetic length, right ventricular mass-to-volume ratio). The latter predictors have recently established CMR as a tool of high significance in evaluation of rTOF patients.Although the role of Holter monitoring findings in rTOF patient-assessment remains unclear, it may be useful in those who are 25 years and older. Implantable cardioverter-defibrillator (ICD) implantation is the first-line treatment for secondary prevention of sudden cardiac death (SCD). rTOF patients suffer from the highest rate of inappropriate and the lowest rate of appropriate ICD shocks, when compared to other congenital heart diseases. As a consequence, ICD implantation for primary SCD prevention should be carefully weighed. Catheter-based ablation therapy leads to high rate of initial success when abolishing monomorphic ventricular tachycardia and intra-atrial reentrant tachycardia, however recurrence rates remain high.

Abstract: Our present data suggest that undocumented arrhythmias are most likely SVTs and are associated with increased RA size.
