Key result
Epicardial catheter ablation emerges as a vital strategy for treating complex arrhythmias in various cardiomyopathies.
Why the study?
Epicardial catheter ablation is commonly performed after failed endocardial ablation, but frequent epicardial substrates in certain cardiomyopathies support considering combined approaches, while applications in supraventricular tachycardias continue to expand.
Epicardial ablation, traditionally used after failed endocardial ablation, is increasingly considered as a primary strategy in certain cardiomyopathies and is expanding to supraventricular tachycardias.
May support earlier epicardial strategies in select cardiomyopathies; leaves open need for prospective comparative trials.
Epicardial catheter ablation is most commonly performed following unsuccessful endocardial ablation. Given the frequency of epicardial substrates in certain cardiomyopathic disease states, however, a combined endocardial-epicardial approach should be considered as a primary treatment strategy. Although epicardial ablation is primarily deployed in patients with ventricular arrhythmias, the role of epicardial approaches in supraventricular tachycardias (eg, atrial fibrillation, inappropriate sinus tachycardia, and-rarely-accessory pathways) is growing, with continued advances being made.

Edward et al. (2019) conducted a review in Cardiac arrhythmias (Ventricular tachycardia, Supraventricular tachycardia). Epicardial catheter ablation was evaluated. Epicardial catheter ablation, often combined with endocardial approaches, is an increasingly important strategy for treating complex ventricular and supraventricular arrhythmias in various cardiomyopathies.
