Arrhythmia recurrence, NYHA symptoms, and mortality were recorded. A total of 26 patients with CA and atrial arrhythmias were included; there were 7 light\u2010chain (AL), 17 wild\u2010type transthyretin (ATTRwt), and 2 mutated transthyretin (ATTRm) amyloidosis patients in total. Of which 13 underwent atrial arrhythmia ablation (CA\u2010A) and 13 underwent AV nodal ablation (CA\u2010AVN). In the CA\u2010A group, there were: 3 with atrial fibrillation (AF); 6 with atrial flutter (AFL); 2 with AF\/AFL; and 2 with atrial tachycardia (AT). One\u2010year and 3\u2010year recurrence\u2010free survival were 75% and 60%, respectively. NYHA symptom improvement 6 months postablation was observed in both CA\u2010A and CA\u2010AVN groups: 7\/10 (70%) and 4\/8 (50%), respectively.
