Early outcomes of transcatheter aortic valve implantation for degenerated aortic bioprostheses in Japanese patients: insights from the AORTIC VIV study
Objective The valve-in-valve procedure, in which a transcatheter heart valve (THV) is implanted into a degenerated bioprosthetic valve, is standardized for high-risk patients. However, this procedure is challenging in Japanese patients who have a small aortic annulus. We investigated the feasibility...

| 520 | |a Objective The valve-in-valve procedure, in which a transcatheter heart valve (THV) is implanted into a degenerated bioprosthetic valve, is standardized for high-risk patients. However, this procedure is challenging in Japanese patients who have a small aortic annulus. We investigated the feasibility, safety, and therapeutic efficacy of the valve-in-valve procedure involving a degenerated stented bioprosthesis, stentless bioprosthesis, or THV. Methods We performed a single-center, non-comparative study of the aortic valve-in-valve procedure (AORTIC VIV study). Beginning in October 2016, the aortic valve-in-valve procedure was performed in seven patients with a stented bioprosthesis, in three patients with a stentless bioprosthesis, and in one patient with a THV. Results No 30-day post-procedure mortality or severe morbidities occurred. The mean echocardiographic gradient in the aortic position improved from 41 (38–48) to 17 (11–22) mmHg at 30 days (p = 0.01). No paravalvular or mild and more transvalvular leaks were detected. The New York Heart Association functional class improved from 2 (2–2.5) to 1 (1–1) at 30 days postoperatively (p = 0.01). Although the procedure failed in two patients with an implanted stentless bioprosthesis, the third patient with a stentless bioprosthesis and the one patient with a degenerated THV successfully underwent the valve-in-valve procedure. Conclusions Feasibility, safety, and potential efficacy of the aortic valve-in-valve procedure were confirmed in selected Japanese patients with a degenerated aortic bioprosthesis. The valve-in-valve procedure for stentless bioprostheses was technically challenging. | ||

| abstract |
Objective The valve-in-valve procedure, in which a transcatheter heart valve (THV) is implanted into a degenerated bioprosthetic valve, is standardized for high-risk patients. However, this procedure is challenging in Japanese patients who have a small aortic annulus. We investigated the feasibility, safety, and therapeutic efficacy of the valve-in-valve procedure involving a degenerated stented bioprosthesis, stentless bioprosthesis, or THV. Methods We performed a single-center, non-comparative study of the aortic valve-in-valve procedure (AORTIC VIV study). Beginning in October 2016, the aortic valve-in-valve procedure was performed in seven patients with a stented bioprosthesis, in three patients with a stentless bioprosthesis, and in one patient with a THV. Results No 30-day post-procedure mortality or severe morbidities occurred. The mean echocardiographic gradient in the aortic position improved from 41 (38–48) to 17 (11–22) mmHg at 30 days (p = 0.01). No paravalvular or mild and more transvalvular leaks were detected. The New York Heart Association functional class improved from 2 (2–2.5) to 1 (1–1) at 30 days postoperatively (p = 0.01). Although the procedure failed in two patients with an implanted stentless bioprosthesis, the third patient with a stentless bioprosthesis and the one patient with a degenerated THV successfully underwent the valve-in-valve procedure. Conclusions Feasibility, safety, and potential efficacy of the aortic valve-in-valve procedure were confirmed in selected Japanese patients with a degenerated aortic bioprosthesis. The valve-in-valve procedure for stentless bioprostheses was technically challenging. © The Japanese Association for Thoracic Surgery 2019 |

However, this procedure is challenging in Japanese patients who have a small aortic annulus. We investigated the feasibility, safety, and therapeutic efficacy of the valve-in-valve procedure involving a degenerated stented bioprosthesis, stentless bioprosthesis, or THV. Methods We performed a single-center, non-comparative study of the aortic valve-in-valve procedure (AORTIC VIV study). Beginning in October 2016, the aortic valve-in-valve procedure was performed in seven patients with a stented bioprosthesis, in three patients with a stentless bioprosthesis, and in one patient with a THV. Results No 30-day post-procedure mortality or severe morbidities occurred. The mean echocardiographic gradient in the aortic position improved from 41 (38–48) to 17 (11–22) mmHg at 30 days (p = 0.01). No paravalvular or mild and more transvalvular leaks were detected. The New York Heart Association functional class improved from 2 (2–2.5) to 1 (1–1) at 30 days postoperatively (p = 0.01). Although the procedure failed in two patients with an implanted stentless bioprosthesis, the third patient with a stentless bioprosthesis and the one patient with a degenerated THV successfully underwent the valve-in-valve procedure. Conclusions Feasibility, safety, and potential efficacy of the aortic valve-in-valve procedure were confirmed in selected Japanese patients with a degenerated aortic bioprosthesis. The valve-in-valve procedure for stentless bioprostheses was technically challenging.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Transcatheter aortic valve implantation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Valve-in-valve</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Stentless valve</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">TAV-in-SAV</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">TAV-in-TAV</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fukushima, Satsuki</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shimahara, Yusuke</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hamatani, Yasuhiro</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kanzaki, Hideaki</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fukuda, Tetsuya</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Izumi, Chisato</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yasuda, Satoshi</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kobayashi, Junjiro</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fujita, Tomoyuki</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">The Japanese journal of thoracic and cardiovascular surgery</subfield><subfield code="d">Tōkyō : Springer Japan, 1998</subfield><subfield code="g">67(2019), 12 vom: 03.
