Most patients were female (13 patients, 87%) and the average age was 43.5\u00a0\u00b1\u00a010.3\u00a0years. The congenital heart disease diagnosis was varied, including Fontan circulation and atrial switch palliation for Transposition of the great arteries. The identified arrhythmias included 21 intra\u2010atrial re\u2010entrant tachycardias and nine focal atrial tachycardias. In 14 cases (66.6%) the procedure was successful, in five cases (23.8%) the procedure was partially successful, and two cases (9.5%) were unsuccessful. There were no procedure\u2010related major adverse events reported. At mean follow up of 15.3\u00a0\u00b1\u00a012.6 months, there were four cases of recurrent arrhythmias (44% of patients), four re\u2010do procedures, three patients (18.8%) were discontinued from their antiarrhythmic medications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Electro\u2010anatomical mapping is useful in the identification and treatment of complex atrial arrhythmias in patients with ACHD.
