We present a novel case describing use of a variable-loop circular PFA catheter (Varipulse, Biosense Webster, Inc., Irvine, CA, USA) via a retrograde aortic approach for left ventricular ventricular tachycardia ablation. Retrograde aortic access was achieved using a long sheath (Ventrax system, Merit Medical, South Jordan, UT) permitting safe unsheathing and manipulation of the variable-loop PFA catheter to avoid entrapment with the mitral valve apparatus. The procedure was completed without complication and no VT recurrence was observed over 3 months follow-up. This case highlights the feasibility of this approach and expands the potential applications of this integrated PFA platform beyond its current indication for atrial fibrillation ablation.<\/jats:p>","DOI":"10.1007\/s10840-026-02441-4","type":"journal-article","created":{"date-parts":[[2026,9,19]],"date-time":"2026-09-19T08:04:09Z","timestamp":1789805049000},"page":"1097-1101","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Left ventricular ablation for ventricular tachycardia using a variable-loop circular pulsed field ablation catheter"],"prefix":"10.1007","volume":"69","author":[{"given":"Sania","family":"Jiwani","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Bogun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas A.","family":"Franzon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jackson J.","family":"Liang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,9,19]]},"reference":[{"key":"2441_CR1","doi-asserted-by":"publisher","first-page":"1660","DOI":"10.1056\/NEJMoa2307291","volume":"389","author":"VY Reddy","year":"2023","unstructured":"Reddy VY, Gerstenfeld EP, Natale A, et al.
