We report a case of intraprocedural catheter malfunction with fibrin deposition potentially leading to a transient neurological deficit during ablation despite optimal anticoagulation.<\/jats:p>\n <\/jats:sec>\n \n Case<\/jats:title>\n A 39\u2010year\u2010old man with symptomatic atrial fibrillation and tachycardia\u2010mediated cardiomyopathy underwent pulmonary vein isolation using the Affera mapping system and Sphere\u20109 lattice tip catheter. During the procedure, despite uninterrupted oral anticoagulation and heparin given to meet manufacturer\u2010recommended activated clotting times, the catheter malfunctioned, and when removed, there was a white solid substance that was seen within the lattice tip. The procedure was stopped prematurely with incomplete pulmonary vein isolation. A pathologist confirmed the white substance was fibrin inside the lattice tip. The patient had symptoms of transient ischemic attack postoperatively and also suffered early recurrence of atrial fibrillation.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n This case demonstrates fibrin deposition and possible embolic events using the Sphere\u20109 lattice tip catheter despite stringent anticoagulation protocols. This highlights the importance of meticulous catheter inspection as well as provides a post\u2010market complication utilizing this catheter.<\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/jce.70443","type":"journal-article","created":{"date-parts":[[2026,7,8]],"date-time":"2026-07-08T20:00:17Z","timestamp":1783540817000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Intraprocedural Fibrin Clot Formation During Pulmonary Vein Isolation With a Lattice\u2010Tip Ablation Catheter"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7321-0100","authenticated-orcid":false,"given":"Nicholas","family":"Roma","sequence":"first","affiliation":[{"name":"Department of Cardiology St. Luke's University Health Network Bethlehem PA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lindsey","family":"Magid","sequence":"additional","affiliation":[{"name":"Department of Cardiology St. Luke's University Health Network Bethlehem PA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nasir","family":"Siddique","sequence":"additional","affiliation":[{"name":"Department of Cardiology St. Luke's University Health Network Bethlehem PA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven","family":"Stevens","sequence":"additional","affiliation":[{"name":"Department of Electrophysiology St. Luke's University Health Network Bethlehem PA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,8]]},"reference":[{"key":"e_1_2_8_2_1","first-page":"2303","article-title":"Dual\u2010Energy Lattice\u2010Tip Ablation System for Persistent Atrial Fibrillation: A Randomized Trial","volume":"30","author":"Anter E.","year":"2024","journal-title":"Nature Medicine (New York, NY, United States)"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/jce.70367"},{"key":"e_1_2_8_4_1","article-title":"Higher Stroke Risk Seen With Pulsed\u2010Field vs Radiofrequency Ablation","author":"Neale T.","year":"2026","journal-title":"TCTMD"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jce.70443","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/jce.70443","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jce.70443","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,17]],"date-time":"2026-07-17T13:58:35Z","timestamp":1784296715000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/jce.70443"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,8]]},"references-count":3,"alternative-id":["10.1111\/jce.70443"],"URL":"https:\/\/doi.org\/10.1111\/jce.70443","archive":["Portico"],"relation":{},"ISSN":["1045-3873","1540-8167"],"issn-type":[{"value":"1045-3873","type":"print"},{"value":"1540-8167","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,7,8]]},"assertion":[{"value":"2026-05-26","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-06-30","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-08","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"jce.70443"}}
