Although pharmacological treatment, cardiac sympathectomy, and implantable cardioverter defibrillators (ICD) have been the mainstay in the management of VF in patients with channelopathies, they are associated with significant adverse effects and complications, leading to poor quality of life. Given these drawbacks, catheter ablation has been proposed as a therapeutic option for patients with channelopathies. Advances in imaging techniques and modern mapping technologies have enabled increased precision in identifying arrhythmia triggers and substrate modification. This has aided our understanding of the underlying pathophysiology of ventricular arrhythmias in channelopathies, highlighting the roles of the Purkinje network and the epicardial right ventricular outflow tract in arrhythmogenesis. This review explores the role of catheter ablation in managing the most common channelopathies (Brugada syndrome, congenital long QT syndrome, short QT syndrome, and catecholaminergic polymorphic ventricular tachycardia). While the initial results for ablation in Brugada syndrome are promising, the long-term efficacy and durability of ablation in different channelopathies require further investigation. Given the genetic and phenotypic heterogeneity of channelopathies, future studies are needed to show whether catheter ablation in patients with channelopathies is associated with a reduction in VF, and psychological distress stemming from recurrent ICD shocks, particularly relative to other available therapeutic options (e.g., quinidine in high-risk Brugada patients).<\/jats:p>","DOI":"10.3390\/jcm13082384","type":"journal-article","created":{"date-parts":[[2024,4,19]],"date-time":"2024-04-19T06:28:09Z","timestamp":1713508089000},"page":"2384","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Catheter Ablation for Channelopathies: When Is Less More?"],"prefix":"10.3390","volume":"13","author":[{"given":"Adhya","family":"Mehta","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Albert Einstein College of Medicine\/Jacobi Medical Center, Bronx, NY 10461, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8659-6850","authenticated-orcid":false,"given":"Rishi","family":"Chandiramani","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Cardiology, Johns Hopkins University School of Medicine, Baltimore, MD 21287, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Binita","family":"Ghosh","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, SSM Health St. Mary Hospital, St. Louis, MO 63117, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0050-5717","authenticated-orcid":false,"given":"Babken","family":"Asatryan","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Cardiology, Johns Hopkins University School of Medicine, Baltimore, MD 21287, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrija","family":"Hajra","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Brigham and Women\u2019s Hospital, Boston, MA 02115, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas S.","family":"Barth","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Cardiology, Johns Hopkins University School of Medicine, Baltimore, MD 21287, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2441","DOI":"10.1056\/NEJMoa1510687","article-title":"A Prospective Study of Sudden Cardiac Death among Children and Young Adults","volume":"374","author":"Bagnall","year":"2016","journal-title":"N.
