Atrial arrhythmias are an important source of morbidity in adults with congenital heart disease (CHD) and have been linked to sudden death in certain subgroups. Whereas intra-atrial reentrant tachycardia (IART) is the most common arrhythmia, the prevalence of atrial fibrillation (AF) is increasing.
