What is the long-term outcome of ablative therapy of postoperative atrial tachyarrhythmia in patients with congenital heart disease?
The long-term outcome of ablative therapy of postoperative atrial tachyarrhythmia in patients with congenital heart disease has been studied in a 2010 Circ Arrhythm Electrophysiol paper by de Groot et al. The study reported that after a median follow-up of 6.2 years, 97% of the patients had freedom from recurrent atrial tachyarrhythmia. However, recurrent atrial tachyarrhythmia was more likely in patients with structural heart disease than in those with isolated arrhythmia. The authors concluded that in patients with congenital heart disease, ablation of atrial tachyarrhythmia is an effective and safe therapy with a low recurrence rate.
