LMNA and atrial fibrillation: Cardiac laminopathies, associated with mutations in the LMNA gene, are a rare (1:2500–5000) inherited disorder characterized by a broad range of clinical manifestations [heart failure (HF), sudden cardiac death (SCD), conduction block, ventricular tachycardias (VTs), and atrial fibrillation (AF)] in early- to mid-adulthood.1–3 There are currently no data on the association between atrioventricular re-entrant tachycardia (AVRT), atrioventricular nodal reciprocating tachycardia (AVNRT), and LMNA-related cardiomyopathy.
