However, the rate of BVD is scarcely reported in current practice. Aims: We aimed to evaluate the rate and predictors of BVD after TAVI based on the VARC-3 criteria. Methods: We retrospectively analysed patients who had undergone TAVI using single-centre data. BVD was reported as exposure-adjusted event rates with a patient-year unit (per 100 patient-years). Predictors of BVD after TAVI were analysed using Fine-Gray competing risk regression to account for the competing risk of death. Results: Among 514 patients, the rate of BVD was 7.5 events per 100 patient-years (n=74) at a median follow-up of 1.9 years. The main cause of BVD was moderate or severe prosthesis-patient mismatch (PPM; n=59). The Fine-Gray model demonstrated that predilatation was associated with a lower rate of BVD, mainly moderate or severe PPM (adjusted subdistribution hazard ratio [sub-HR] 0.42, 95% confidence interval [CI]: 0.21-0.88). In a subgroup analysis, the patients with a small aortic annulus (area &lt;400 mm<sup>2</sup> or perimeter &lt;72 mm) tended to benefit from predilatation (p for interaction=0.03). The same regression model also demonstrated that a small balloon-expandable valve (BEV; ≤23 mm) was associated with a higher rate of BVD (adjusted sub-HR 2.46, 95% CI: 1.38-4.38). Conclusions: Our study suggested that the rate of BVD in patients undergoing TAVI is relatively low at midterm follow-up. Predilatation, particularly in small annuli and small BEV might have an impact on BVD, mainly caused by moderate or severe PPM, after TAVI.</p>","subitem_description_language":"eng"}]},"item_1551264974654":{"attribute_name":"Date","attribute_value_mlt":[{"subitem_date_issued_datetime":"2023","subitem_date_issued_type":"Issued"}]},"item_1551265002099":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1551265032053":{"attribute_name":"item_1551265032053","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1551265227803":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"85153968990","subitem_relation_type_select":"QABO"}},{"subitem_relation_type":"isPartOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"2426-3958","subitem_relation_type_select":"ISSN"}}]},"item_1551265438256":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_source_title":"AsiaIntervention"}]},"item_1551265463411":{"attribute_name":"巻","attribute_value_mlt":[{"subitem_volume":"9"}]},"item_1551265520160":{"attribute_name":"号","attribute_value_mlt":[{"subitem_issue":"1"}]},"item_1551265553273":{"attribute_name":"ページ数","attribute_value_mlt":[{"subitem_number_of_pages":"8"}]},"item_1551265569218":{"attribute_name":"開始ページ","attribute_value_mlt":[{"subitem_start_page":"87"},{"subitem_start_page":"94"}]},"item_title":"Predictors of bioprosthetic valve dysfunction after transcatheter aortic valve implantation","item_type_id":"12","owner":"1","path":["1741828256493"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-03-31"},"publish_date":"2025-03-31","publish_status":"0","recid":"2026507","relation_version_is_last":true,"system_identifier_doi":{"attribute_name":"Persistent Identifier(DOI)","attribute_value_mlt":[{"subitem_systemidt_identifier":"https://pure.teikyo.jp/en/publications/016b3f90-b5eb-4574-b3b1-c36541d52022","subitem_systemidt_identifier_type":"URI"},{"subitem_systemidt_identifier":"https://doi.org/10.4244/AIJ-D-22-00067","subitem_systemidt_identifier_type":"DOI"}]},"title":["Predictors of bioprosthetic valve dysfunction after transcatheter aortic valve implantation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2025-04-17T10:16:52.666641+00:00"}
