Fourteen patients (78%) were men. Five patients had Marfan syndrome and 2 patients had bicuspid aortic valve. Two patients had coronary malperfusion and 1 patient had cerebral malperfusion. All 18 patients underwent aortic root remodelling with external ring annuloplasty. Cusp repair using central cusp plication was required in 9 patients. Concomitant procedures were hemiarch replacement in 8 patients, total arch replacement in 7 patients, partial arch replacement in 1 patient and coronary artery bypass grafting to the right coronary artery in 3 patients. Thirty-day mortality rate was 5.6% (1 of 18). Postoperative echocardiography showed aortic regurgitation of &amp;lt;1+ in all patients. During follow-up (mean 56\u2009\u00b1\u200941\u2009months), 1 case of recurrent aortic regurgitation required aortic valve replacement.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>Aortic root remodelling with external ring annuloplasty may be an appropriate treatment in middle-aged or younger patients presenting with acute type A aortic dissection.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/icvts\/ivz227","type":"journal-article","created":{"date-parts":[[2019,8,28]],"date-time":"2019-08-28T15:26:05Z","timestamp":1567005965000},"page":"85-90","source":"Crossref","is-referenced-by-count":7,"title":["Aortic root remodelling with external ring annuloplasty in acute type A aortic dissection"],"prefix":"10.1093","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3414-497X","authenticated-orcid":false,"given":"Yasuyuki","family":"Kato","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery, Saitama Sekishinkai Hospital, Saitama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenichi","family":"Sasaki","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Saitama Sekishinkai Hospital, Saitama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hidetaka","family":"Yamauchi","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Saitama Sekishinkai Hospital, Saitama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuyuki","family":"Kanno","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Saitama Sekishinkai Hospital, Saitama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taiyo","family":"Jinno","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Saitama Sekishinkai Hospital, Saitama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muneaki","family":"Yamada","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Saitama Sekishinkai Hospital, Saitama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Kiyama","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Saitama Sekishinkai Hospital, Saitama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshiya","family":"Koyanagi","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Surgery, Saitama Sekishinkai Hospital, Saitama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2019,10,9]]},"reference":[{"key":"2019122407374707300_ivz227-B1","doi-asserted-by":"crossref","first-page":"156","DOI":"10.21037\/acs.2016.05.06","article-title":"Hemiarch versus total arch replacement in acute type A dissection: a systemic review and meta-analysis","volume":"5","author":"Poon","year":"2016","journal-title":"Ann Cardiothorac Surg"},{"key":"2019122407374707300_ivz227-B2","doi-asserted-by":"crossref","first-page":"317","DOI":"10.21037\/acs.2016.07.06","article-title":"Outcomes and management of type A intramural hematoma","volume":"5","author":"Sandhu","year":"2016","journal-title":"Ann Cardiothorac Surg"},{"key":"2019122407374707300_ivz227-B3","doi-asserted-by":"crossref","first-page":"2078","DOI":"10.1016\/j.athoracsur.2014.06.070","article-title":"Root replacement surgery versus more conservative management during type A acute aortic dissection repair","volume":"98","author":"Eusanio","year":"2014","journal-title":"Ann Thorac Surg"},{"key":"2019122407374707300_ivz227-B4","doi-asserted-by":"crossref","first-page":"223","DOI":"10.1093\/ejcts\/ezw038","article-title":"Surgical management of aortic root in type A acute aortic dissection: a propensity-score analysis","volume":"50","author":"Castrovinci","year":"2016","journal-title":"Eur J Cardiothorac Surg"},{"key":"2019122407374707300_ivz227-B5","doi-asserted-by":"crossref","first-page":"e220","DOI":"10.1093\/ejcts\/ezu099","article-title":"Aortic valve preservation and repair in acute type A aortic dissection","volume":"45","author":"Saczkowski","year":"2014","journal-title":"Eur J Cardiothorac Surg"},{"key":"2019122407374707300_ivz227-B6","doi-asserted-by":"crossref","first-page":"S253","DOI":"10.1161\/CIRCULATIONAHA.112.000338","article-title":"Longevity after aortic root replacement.
