Regular surveillance in these patients after the operation is necessary. Herein, we present an 11-year-old boy born with tricuspid atresia, a discordant ventriculo-arterial connection and a hypoplastic aortic arch, who was palliated initially with a hybrid stage I procedure involving a reversed Blalock\u2013Taussig shunt, followed by comprehensive stage II and then, an extra-cardiac fenestrated Fontan operation. The patient developed an aortic root aneurysm and severe aortic regurgitation. He was electively taken into the operating room, where cardiopulmonary bypass was established through a peripheral cannulation of the femoral vessels due to the high risk nature of the reoperation. A mechanical Bentall procedure was performed without residual lesions and the native ascending aorta was anastomosed as a single coronary button to the anterior wall of the graft.<\/jats:p>","DOI":"10.1093\/icvts\/ivaa139","type":"journal-article","created":{"date-parts":[[2020,7,1]],"date-time":"2020-07-01T19:09:44Z","timestamp":1593630584000},"page":"578-579","source":"Crossref","is-referenced-by-count":7,"title":["Bentall procedure for the repair of a neoaortic aneurysm after the Norwood procedure in a patient with tricuspid atresia and a discordant ventriculo-arterial connection"],"prefix":"10.1093","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4221-1346","authenticated-orcid":false,"given":"Juan","family":"Contreras","sequence":"first","affiliation":[{"name":"Division of Cardiovascular Surgery, Labatt Family Heart Centre, The Hospital for Sick Children, University of Toronto, Toronto, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Badr","family":"Bannan","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Surgery, Labatt Family Heart Centre, The Hospital for Sick Children, University of Toronto, Toronto, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajiv","family":"Chaturvedi","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Surgery, Labatt Family Heart Centre, The Hospital for Sick Children, University of Toronto, Toronto, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3671-5337","authenticated-orcid":false,"given":"David J","family":"Barron","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Surgery, Labatt Family Heart Centre, The Hospital for Sick Children, University of Toronto, Toronto, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,9,4]]},"reference":[{"key":"2020102213252126400_ivaa139-B1","doi-asserted-by":"crossref","first-page":"533","DOI":"10.1016\/S0735-1097(03)00715-0","article-title":"Neo-aortic root dilation and valve regurgitation up to 21 years after staged reconstruction for hypoplastic left heart syndrome","volume":"42","author":"Cohen","year":"2003","journal-title":"J Am Coll Cardiol"},{"key":"2020102213252126400_ivaa139-B2","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1016\/j.athoracsur.2004.10.056","article-title":"Neoaortic aneurysm after stage I Norwood reconstruction","volume":"79","author":"Ehsan","year":"2005","journal-title":"Ann Thorac Surg"},{"key":"2020102213252126400_ivaa139-B3","doi-asserted-by":"crossref","first-page":"1083","DOI":"10.1016\/j.jtcvs.2010.07.076","article-title":"Valve-sparing neo-aortic root replacement after Fontan completion for hypoplastic left heart syndrome","volume":"141","author":"Pizarro","year":"2011","journal-title":"J Thorac Cardiovasc Surg"},{"key":"2020102213252126400_ivaa139-B4","doi-asserted-by":"crossref","first-page":"478","DOI":"10.1016\/j.jtcvs.2005.09.047","article-title":"Repair of symptomatic neoaortic aneurysm after third-stage palliation for hypoplastic left heart syndrome","volume":"131","author":"Shuhaiber","year":"2006","journal-title":"J Thorac Cardiovasc Surg"},{"key":"2020102213252126400_ivaa139-B5","doi-asserted-by":"crossref","first-page":"e55","DOI":"10.1016\/j.jtcvs.2013.12.056","article-title":"Aneurysm formation after the Norwood procedure: case report and review of the literature","volume":"147","author":"Herrmann","year":"2014","journal-title":"J Thorac Cardiovasc Surg"}],"container-title":["Interactive CardioVascular and Thoracic Surgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/icvts\/article-pdf\/31\/4\/578\/33989191\/ivaa139.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/icvts\/article-pdf\/31\/4\/578\/33989191\/ivaa139.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,10,22]],"date-time":"2020-10-22T17:25:39Z","timestamp":1603387539000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/icvts\/article\/31\/4\/578\/5901683"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,9,4]]},"references-count":5,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2020,9,4]]},"published-print":{"date-parts":[[2020,10,1]]}},"URL":"https:\/\/doi.org\/10.1093\/icvts\/ivaa139","relation":{},"ISSN":["1569-9285"],"issn-type":[{"value":"1569-9285","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2020,10]]},"published":{"date-parts":[[2020,9,4]]}}}
