However, uniform transmural energy delivery may induce excessive tissue modification and unintended effects on adjacent structures. Pulsed field ablation of the right superior pulmonary vein (RSPV) can result in conduction delay within the superior vena cava (SVC), but its electrophysiological properties remain poorly characterized.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case summary<\/jats:title>\n                    <jats:p>An 81-year-old man with ischaemic cardiomyopathy, chronic heart failure, and paroxysmal AF underwent PFA for pulmonary vein isolation and posterior wall isolation. Pre-ablation mapping revealed myocardial sleeves within the SVC. Post-PFA mapping demonstrated complete SVC isolation. However, conduction recurred following adenosine triphosphate administration, and ectopic activity originated from the SVC. Circumferential radiofrequency ablation was subsequently performed, achieving durable SVC isolation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>This case demonstrates that PFA of the RSPV can lead to incidental SVC isolation. The presence of adenosine-induced dormant conduction highlights the potential for late reconnection, while the observation of ectopic activity supports the need for adjunctive ablation. Pulsed field ablation may unintentionally affect adjacent myocardial tissue, including the SVC and components of the cardiac conduction system. Therefore, careful electrophysiological assessment and monitoring of conduction recovery are essential to prevent arrhythmogenic triggers and to ensure durable isolation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytag027","type":"journal-article","created":{"date-parts":[[2026,1,21]],"date-time":"2026-01-21T12:45:12Z","timestamp":1768999512000},"source":"Crossref","is-referenced-by-count":0,"title":["Electrophysiological evaluation of incidental superior vena cava isolation following pulsed field ablation: a case report"],"prefix":"10.1093","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9828-0300","authenticated-orcid":false,"given":"Shin","family":"Hasegawa","sequence":"first","affiliation":[{"name":"Department of Cardiology, Gifu Heart Center , 4-14-4 Yabutaminami, Gifu City, Gifu, 500-8384 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-3438-7722","authenticated-orcid":false,"given":"Taiji","family":"Miyake","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Gifu Heart Center , 4-14-4 Yabutaminami, Gifu City, Gifu, 500-8384 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoriaki","family":"Shinoda","sequence":"additional","affiliation":[{"name":"Department of Clinical Engineering, Gifu Heart Center , 4-14-4 Yabutaminami, Gifu City, Gifu, 500-8384 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mutsumi","family":"Aoyama","sequence":"additional","affiliation":[{"name":"Department of Clinical Engineering, Gifu Heart Center , 4-14-4 Yabutaminami, Gifu City, Gifu, 500-8384 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hitoshi","family":"Matsuo","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Gifu Heart Center , 4-14-4 Yabutaminami, Gifu City, Gifu, 500-8384 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2026,1,23]]},"reference":[{"key":"2026021309362342900_ytag027-B1","doi-asserted-by":"crossref","first-page":"1497","DOI":"10.1056\/NEJMoa2502280","article-title":"Pulsed field or cryoballoon ablation for paroxysmal atrial fibrillation","volume":"392","author":"Reichlin","year":"2025","journal-title":"N Engl J Med"},{"key":"2026021309362342900_ytag027-B2","doi-asserted-by":"crossref","first-page":"345","DOI":"10.1111\/jce.15349","article-title":"Pulsed-field ablation combined with ultrahigh-density mapping in patients undergoing catheter ablation for atrial fibrillation: practical and electrophysiological considerations","volume":"33","author":"Gunawardene","year":"2022","journal-title":"J Cardiovasc Electrophysiol"},{"key":"2026021309362342900_ytag027-B3","doi-asserted-by":"crossref","first-page":"1549","DOI":"10.1007\/s10840-025-02055-2","article-title":"Unintended isolation of the left atrial appendage: a rare complication of pulsed-field ablation","volume":"68","author":"Takai","year":"2025","journal-title":"J Interv Card Electrophysiol"},{"key":"2026021309362342900_ytag027-B4","doi-asserted-by":"crossref","first-page":"1948","DOI":"10.1111\/jce.16759","article-title":"Incidence and characteristics of superior vena cava impact after pulsed-field ablation of the right pulmonary veins","volume":"36","author":"Matsuura","year":"2025","journal-title":"J Cardiovasc Electrophysiol"},{"key":"2026021309362342900_ytag027-B5","doi-asserted-by":"crossref","first-page":"433","DOI":"10.1093\/europace\/euac211","article-title":"Findings from repeat ablation using high-density mapping after pulmonary vein isolation with pulsed field ablation","volume":"25","author":"Tohoku","year":"2023","journal-title":"Europace"},{"key":"2026021309362342900_ytag027-B6","doi-asserted-by":"crossref","first-page":"e263763","DOI":"10.1136\/bcr-2024-263763","article-title":"Transient conduction disturbance during pulsed-field ablation for atrial fibrillation in a patient with pre-existing conduction disease","volume":"18","author":"Ohn","year":"2025","journal-title":"BMJ Case Rep"},{"key":"2026021309362342900_ytag027-B7","doi-asserted-by":"crossref","first-page":"e011780","DOI":"10.1161\/CIRCEP.122.011780","article-title":"Paroxysmal atrial fibrillation ablation using a novel variable-loop biphasic pulsed field ablation catheter integrated with a 3-dimensional mapping system: 1-year outcomes of the multicenter inspIRE study","volume":"16","author":"Duytschaever","year":"2023","journal-title":"Circ Arrhythm Electrophysiol"},{"key":"2026021309362342900_ytag027-B8","doi-asserted-by":"crossref","first-page":"1660","DOI":"10.1056\/NEJMoa2307291","article-title":"; ADVENT investigators.
