Transthoracic echocardiography revealed severe aortic regurgitation and a vegetation-like structure on the aortic valve which protruding into the left ventricular outflow tract. Although contrast-enhanced computed tomography revealed enlargement of the aortic root of 47 mm in diameter, dissection findings were not noted. We diagnosed infective endocarditis of aortic valve and performed an urgent surgical treatment. However, intraoperative transesophageal echocardiography revealed a circumferential dissection confined to the aortic root and the protrusion of the intimal flap into the left ventricular outflow tract, with no evidence of aortic valve vegetation or degeneration. Consequently, we made the true diagnosis of acute type A aortic dissection localized to the aortic root. An aortic root replacement using On-X 21 mm was successfully performed, and the postoperative recovery was uneventful.\nLocalized aortic root dissection is difficult to diagnose because it is rare and can easily be missed on transthoracic echocardiography or contrast-enhanced computed tomography. In cases where transthoracic echocardiography and contrast-enhanced computed tomography fail to provide conclusive evidence of aortic dissection, transesophageal echocardiography should be considered as a further diagnostic approach.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_30001_file22":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-07-03"}],"filename":"akitai50_3_4(127).pdf","filesize":[{"value":"751.1 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://air.repo.nii.ac.jp/record/2001687/files/akitai50_3_4(127).pdf"},"version_id":"8fd50906-d5d7-43ec-85a4-356c32db39a4"}]},"item_30001_identifier_registration13":{"attribute_name":"identifier_registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20569/0002001687","subitem_identifier_reg_type":"JaLC"}]},"item_30001_language10":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_30001_publisher9":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Akita Medical Society","subitem_publisher_language":"en"}]},"item_30001_resource_type11":{"attribute_name":"item_30001_resource_type11","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30001_source_identifier16":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"0386-6106","subitem_source_identifier_type":"PISSN"},{"subitem_source_identifier":"AN00009294","subitem_source_identifier_type":"NCID"}]},"item_30001_subject7":{"attribute_name":"主題","attribute_value_mlt":[{"subitem_subject":"Acute type A aortic dissection","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Localized aortic root dissection","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Aortic regurgitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Transesophageal echocardiography","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_30001_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"LOCALIZED AORTIC ROOT DISSECTION DETECTABLE ONLY BY TRANSESOPHAGEAL ECHOCARDIOGRAPHY : A CASE REPORT","subitem_title_language":"en"}]},"item_30001_version_type12":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"LOCALIZED AORTIC ROOT DISSECTION DETECTABLE ONLY BY TRANSESOPHAGEAL ECHOCARDIOGRAPHY : A CASE REPORT","item_type_id":"30001","owner":"56","path":["1748588377054"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-07-03"},"publish_date":"2025-07-03","publish_status":"0","recid":"2001687","relation_version_is_last":true,"title":["LOCALIZED AORTIC ROOT DISSECTION DETECTABLE ONLY BY TRANSESOPHAGEAL ECHOCARDIOGRAPHY : A CASE REPORT"],"weko_creator_id":"56","weko_shared_id":-1},"updated":"2025-07-03T02:41:51.499453+00:00"}
