Some of the markers of \u201carrhythmic MVP\u201d include inverted\/biphasic T\u2010waves, QT prolongation, and polymorphic premature ventricular contractions (PVCs) originating from the left ventricular outflow tract and papillary muscles (PMs). The genesis of arrhythmias in MVP recognizes the combination of the substrate (fibrosis) and the trigger (mechanical stretch). Therefore, ablation of ventricular arrhythmias originating from PMs in a patient with MVP can be considered an adjunctive strategy to lower the arrhythmic burden and reduce the risk of ICD shocks.<\/jats:p>","DOI":"10.1111\/echo.15529","type":"journal-article","created":{"date-parts":[[2023,2,1]],"date-time":"2023-02-01T07:49:00Z","timestamp":1675237740000},"page":"271-275","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Papillary muscle ventricular ectopy ablation in a malignant mitral valve prolapse"],"prefix":"10.1111","volume":"40","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6683-6781","authenticated-orcid":false,"given":"Sergio","family":"Conti","sequence":"first","affiliation":[{"name":"Department of Cardiology, Electrophysiology Department ARNAS Ospedali Civico Di Cristina Benfratelli  Palermo Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"Sabatino","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Electrophysiology Department ARNAS Ospedali Civico Di Cristina Benfratelli  Palermo Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlo","family":"Caserta","sequence":"additional","affiliation":[{"name":"Department of Cardiology, cardiovascular imaging division ARNAS Ospedali Civico Di Cristina Benfratelli  Palermo Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giuseppe","family":"Sgarito","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Electrophysiology Department ARNAS Ospedali Civico Di Cristina Benfratelli  Palermo Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,1,31]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamacardio.2020.1412"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.118.034075"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCIMAGING.116.005248"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehab395"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/euac125"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/heartjnl-2017-312932"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1161\/JAHA.118.010584"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.116.004005"},{"issue":"12","key":"e_1_2_8_10_1","article-title":"The outcome of ventricular arrhythmias associated with mitral valve prolapse after catheter ablation: a systematic review and meta\u2010analysis","volume":"13","author":"Wibawa K","year":"2021","journal-title":"Cureus"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10840-020-00775-1"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcmg.2021.04.029"}],"container-title":["Echocardiography"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/echo.15529","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/echo.15529","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/echo.15529","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,21]],"date-time":"2023-08-21T15:20:16Z","timestamp":1692631216000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/echo.15529"}},"subtitle":["Ablation in Malignant Mitral Valve Prolapse"],"short-title":[],"issued":{"date-parts":[[2023,1,31]]},"references-count":11,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2023,3]]}},"alternative-id":["10.1111\/echo.15529"],"URL":"https:\/\/doi.org\/10.1111\/echo.15529","archive":["Portico"],"relation":{},"ISSN":["0742-2822","1540-8175"],"issn-type":[{"type":"print","value":"0742-2822"},{"type":"electronic","value":"1540-8175"}],"subject":[],"published":{"date-parts":[[2023,1,31]]},"assertion":[{"value":"2022-09-10","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-01-08","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-01-31","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
