We analyzed annular motion and leaflet movement with a rigid or flexible ring and without a ring using an isolated swine working heart model. Hearts of 10 swine (weight: 40\u201350 kg) were used for a rigid ring (n=5) and a flexible ring (n=5). Four ultrasound crystal tips were fixed around the annulus and an annuloplasty ring was implanted in the isolated heart. In the working heart mode, measurement of mitral annular dimension was acquired by sonomicrometry. Images of mitral valve motion were acquired by a high-speed video camera. The same analyses were performed after removing the artificial ring. The antero-posterior diameter of the diastole distance was significantly reduced in the flexible ring (21.59\u00b10.71 mm) and rigid ring (15.93\u00b11.88 mm) compared with no ring (23.51\u00b12.01 mm). The flexible ring made the transverse diameter shrink significantly more than did the rigid ring. The contraction range of the transverse diameter was significantly smaller in the flexible ring compared with no ring. The duration of opening to closing of the mitral leaflet with the rigid (124.7\u00b14.4 ms) and flexible rings (107.9\u00b13.5 ms) was significantly shorter than that with no ring (168\u00b136.5 ms). Annuloplasty rings allow simplicity of leaflet motion, regardless of the type of artificial ring. In a flexible ring, the mitral annulus shows a vertically long shape, suggesting preservation of posterior annular movement.", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/nagjms.81.2.207", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Nagoya University Graduate School of Medicine, School of Medicine"}]}, "item_9_relation_43": {"attribute_name": "\u7570\u7248\u3067\u3042\u308b", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://www.med.nagoya-u.ac.jp/medlib/nagoya_j_med_sci/812.html ", "subitem_relation_type_select": "URI"}}]}, "item_9_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_source_id_61": {"attribute_name": "ISSN\uff08Online\uff09", "attribute_value_mlt": [{"subitem_source_identifier": "2186-3326", "subitem_source_identifier_type": "ISSN"}]}, "item_9_source_id_7": {"attribute_name": "ISSN\uff08print\uff09", "attribute_value_mlt": [{"subitem_source_identifier": "0027-7622", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Yokote, Jun"}], "nameIdentifiers": [{"nameIdentifier": "92000", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Araki, Yoshimori"}], "nameIdentifiers": [{"nameIdentifier": "92001", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Saito, Shunei"}], "nameIdentifiers": [{"nameIdentifier": "92002", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hasegawa, Hiroki"}], "nameIdentifiers": [{"nameIdentifier": "92003", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Usui, Akihiko"}], "nameIdentifiers": [{"nameIdentifier": "92004", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-06-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "04_Yokote.pdf", "filesize": [{"value": "3.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 3400000.0, "url": {"label": "04_Yokote.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/28238/files/04_Yokote.pdf"}, "version_id": "5ecd6e0c-70fc-4b5e-afe6-f639ca5e779b"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "mitral valve", "subitem_subject_scheme": "Other"}, {"subitem_subject": "annuloplasty ring", "subitem_subject_scheme": "Other"}, {"subitem_subject": "heart physiology", "subitem_subject_scheme": "Other"}, {"subitem_subject": "isolated heart model", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Effect of an artificial ring on mitral valve function", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Effect of an artificial ring on mitral valve function"}]}, "item_type_id": "9", "owner": "1", "path": ["499/508/509/2418"], "permalink_uri": "https://doi.org/10.18999/nagjms.81.2.207", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2019-06-13"}, "publish_date": "2019-06-13", "publish_status": "0", "recid": "28238", "relation": {}, "relation_version_is_last": true, "title": ["Effect of an artificial ring on mitral valve function"], "weko_shared_id": 3}
