Mitral valve trauma at the time of atrial fibrillation (AF) ablations remains a rare yet emergent situation that requires prompt diagnosis and management to prevent the long-term sequelae of heart failure secondary to MV dysfunction.<\/jats:p>\n <\/jats:sec>\n \n Case summary<\/jats:title>\n We present a case of a 69-year-old female with symptomatic paroxysmal AF and atrial flutter who underwent a combined ablation procedure. During the pulmonary vein isolation procedure, the mapping catheter became entangled within the MV apparatus but was freed. She presented to our hospital 2 weeks later with dyspnoea, lethargy, and a cough. Clinical examination revealed a pansystolic murmur and right moderate pleural effusion. Transthoracic echocardiogram (TTE) demonstrated a flail posterior MV leaflet with severe eccentric mitral regurgitation (MR). She underwent urgent valve repair at the regional cardiothoracic centre. Upon review 2 months later, she was symptom free with surveillance TTE demonstrating a preserved left ventricular systolic function with a trace of MR.<\/jats:p>\n <\/jats:sec>\n \n Discussion<\/jats:title>\n Mitral valve injury secondary to catheter entrapment at the time of left-sided ablations is a rare yet serious complication and can present as an emergent situation requiring prompt recognition and early surgical management to salvage valve and cardiac function.<\/jats:p>\n <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytaa311","type":"journal-article","created":{"date-parts":[[2020,9,18]],"date-time":"2020-09-18T06:34:35Z","timestamp":1600410875000},"page":"1-6","source":"Crossref","is-referenced-by-count":3,"title":["Mapping catheter-related mitral valve injury: a case report"],"prefix":"10.1093","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4761-7297","authenticated-orcid":false,"given":"Simran","family":"Shergill","sequence":"first","affiliation":[{"name":"Department of Cardiology, South Warwickshire NHS Foundation Trust, Lakin Road, Warwick CV34 5BW, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4563-6454","authenticated-orcid":false,"given":"Nigel R A","family":"Clarke","sequence":"additional","affiliation":[{"name":"Department of Cardiology, South Warwickshire NHS Foundation Trust, Lakin Road, Warwick CV34 5BW, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,9,18]]},"reference":[{"key":"2020110901535261400_ytaa311-B1","doi-asserted-by":"crossref","first-page":"1279","DOI":"10.1093\/europace\/eux233","article-title":"Complications of pulmonary vein isolation in atrial fibrillation: predictors and comparison between four different ablation techniques: results from the Middelheim PVI-registry","volume":"20","author":"De Greef","year":"2018","journal-title":"EP Europace"},{"key":"2020110901535261400_ytaa311-B2","first-page":"284","article-title":"Life-threatening complications of atrial fibrillation ablation: 16-year experience in a large prospective tertiary care cohort","volume":"5","author":"Rehman","year":"2019","journal-title":"JACC Clin Electrophysiol"},{"key":"2020110901535261400_ytaa311-B3","doi-asserted-by":"crossref","first-page":"609","DOI":"10.1001\/jama.2013.8643","article-title":"Association between early surgical intervention vs watchful waiting and outcomes for mitral regurgitation due to flail mitral valve leaflets","volume":"310","author":"Suri","year":"2013","journal-title":"JAMA"},{"key":"2020110901535261400_ytaa311-B4","doi-asserted-by":"crossref","first-page":"971","DOI":"10.1111\/jce.12439","article-title":"Catheter ablation related mitral valve injury: the importance of early recognition and rescue mitral valve repair","volume":"25","author":"Desimone","year":"2014","journal-title":"J Cardiovasc Electrophysiol"},{"key":"2020110901535261400_ytaa311-B5","doi-asserted-by":"crossref","first-page":"17","DOI":"10.1016\/j.hrthm.2006.09.016","article-title":"Entrapment of circular mapping catheter in the mitral valve","volume":"4","author":"Kesek","year":"2007","journal-title":"Heart Rhythm"},{"key":"2020110901535261400_ytaa311-B6","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1161\/CIRCEP.109.859116","article-title":"Updated worldwide survey on the methods, efficacy, and safety of catheter ablation for human atrial fibrillation","volume":"3","author":"Cappato","year":"2010","journal-title":"Circ Arrhythm Electrophysiol"},{"key":"2020110901535261400_ytaa311-B7","doi-asserted-by":"crossref","first-page":"819","DOI":"10.1046\/j.1540-8167.2002.00819.x","article-title":"Circular mapping catheter entrapment in the mitral valve apparatus: a previously unrecognized complication of focal atrial fibrillation ablation","volume":"13","author":"Wu","year":"2002","journal-title":"J Cardiovasc Electrophysiol"},{"key":"2020110901535261400_ytaa311-B8","doi-asserted-by":"crossref","first-page":"e1","DOI":"10.1093\/europace\/eux274","article-title":"HRS\/EHRA\/ECAS\/APHRS\/SOLAECE expert consensus statement on catheter and surgical ablation of atrial fibrillation","volume":"20","author":"Calkins","year":"2018","journal-title":"EP Europace"}],"container-title":["European Heart Journal -
