Abstract:
Inherited cardiac arrhythmias are genetic disorders that impact the heart's electrical circuitry. These disorders are caused by inherited mutations and markedly increase the mortality risk of affected individuals. Conventional treatments, such as pharmacological agents for rate and rhythm control or surgical interventions, are often not efficacious and cause long-term complications. Gene therapy has recently emerged as a feasible and potentially curative approach for treating inherited cardiac arrhythmia syndromes. Advancements in elucidating the molecular mechanisms, pinpointing essential candidate genes, and improving gene delivery have rendered gene therapy as a feasible treatment alternative. This review examines recent studies on gene therapy applications in Brugada syndrome, catecholaminergic polymorphic ventricular tachycardia, long QT syndrome, familial atrial fibrillation, and arrhythmogenic cardiomyopathy. Additionally, we analyze current advancements in viral and non-viral gene delivery methods, highlighting their therapeutic potential and related challenges.
