Thermal ablation of this vessel carries risks of phrenic nerve palsy and coronary artery spasm, whereas pulsed field ablation still lacks procedural guidance for the PLSVC diameter taper, which narrows from the distal segment to a dilated coronary sinus ostium. We report two contact strategies applied in three patients: a guidewire\u2010anchored rail with steerable sheath tension for a fixed\u2010loop catheter, and loop\u2010diameter adjustment for a variable\u2010loop catheter. Acute bidirectional block was confirmed by pacing in all three cases; in one case, dissociated spontaneous potentials provided an endpoint more stringent than atrial fibrillation termination alone. No complications occurred. These findings provide initial guidance for ablating the tapered PLSVC, although long\u2010term durability requires prospective validation.<\/jats:p>","DOI":"10.1111\/pace.70451","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T16:06:07Z","timestamp":1790265967000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Contact Strategies and Isolation Endpoints in Pulsed Field Ablation of Persistent Left Superior Vena Cava: A Case Series"],"prefix":"10.1111","author":[{"given":"Lu","family":"Bai","sequence":"first","affiliation":[{"name":"Department of Cardiology West China Hospital Sichuan University  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruikun","family":"Jia","sequence":"additional","affiliation":[{"name":"Department of Cardiology West China Hospital Sichuan University  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4314-3525","authenticated-orcid":false,"given":"Xinmeng","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Cardiology West China Hospital Sichuan University  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinling","family":"Fu","sequence":"additional","affiliation":[{"name":"Department of Cardiology West China Hospital Sichuan University  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5322-2641","authenticated-orcid":false,"given":"Kaijun","family":"Cui","sequence":"additional","affiliation":[{"name":"Department of Cardiology West China Hospital Sichuan University  Chengdu Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,24]]},"reference":[{"issue":"8","key":"e_1_2_10_2_1","doi-asserted-by":"crossref","first-page":"1214","DOI":"10.1016\/j.amjcard.2013.05.079","article-title":"Prevalence of Persistent Superior Vena Cava and Association With Congenital Heart Anomalies","volume":"112","author":"Perles Z.","year":"2013","journal-title":"American Journal of Cardiology"},{"issue":"12","key":"e_1_2_10_3_1","doi-asserted-by":"crossref","first-page":"1755","DOI":"10.1016\/j.hrthm.2010.08.005","article-title":"Catheter Ablation of Atrial Fibrillation in Patients With Persistent Left Superior Vena Cava Is Associated With Major Intraprocedural Complications","volume":"7","author":"Wissner E.","year":"2010","journal-title":"Heart Rhythm"},{"issue":"5","key":"e_1_2_10_4_1","doi-asserted-by":"crossref","first-page":"301","DOI":"10.1016\/j.jaccas.2022.01.015","article-title":"Pulsed Field Ablation for Persistent Superior Vena Cava: New Solution for an Old Problem","volume":"4","author":"Tohoku S.","year":"2022","journal-title":"JACC Case Reports"},{"issue":"12","key":"e_1_2_10_5_1","doi-asserted-by":"crossref","first-page":"1414","DOI":"10.1111\/pace.70071","article-title":"Pulse Field Ablation for Persistent Atrial Fibrillation: Targeting the Persistent Superior Vena Cava","volume":"48","author":"V\u00e1zquez\u2010Calvo S.","year":"2025","journal-title":"Pacing and Clinical Electrophysiology"},{"key":"e_1_2_10_6_1","doi-asserted-by":"crossref","DOI":"10.1016\/j.jaccas.2026.108569","article-title":"Pulsed Field Ablation of Persistent Left Superior Vena Cava in an Athlete With Atrial Fibrillation","volume":"31","author":"Mi J.","year":"2026","journal-title":"JACC Case Reports"},{"issue":"8","key":"e_1_2_10_7_1","doi-asserted-by":"crossref","first-page":"1222","DOI":"10.1016\/j.hroo.2025.05.013","article-title":"Isolation of a Persistent Left Superior Vena Cava Using the Circular Array Pulsed Field Ablation Cathete","volume":"6","author":"Mizuno Y.","year":"2025","journal-title":"Heart Rhythm O2"},{"issue":"7","key":"e_1_2_10_8_1","doi-asserted-by":"crossref","first-page":"828","DOI":"10.1161\/01.CIR.0000116753.56467.BC","article-title":"Atrial Fibrillation Originating From Persistent Left Superior Vena Cava","volume":"109","author":"Hsu L.
