What is the long-term outcome after ablative therapy of postoperative atrial tachyarrhythmia in patients with congenital heart disease?
A study by de Groot et al. (2010) found that long-term outcome after ablative therapy of postoperative atrial tachyarrhythmia in patients with congenital heart disease was generally favorable. The authors reported that most patients showed significant improvement in symptoms and an absence of recurrent arrhythmia for the duration of follow-up (up to five years). However, they noted that some patients still experienced recurrent arrhythmia, and the rate of recurrence was higher in those with structural heart disease or a previous history of arrhythmia.
