Background:
An 80-year-old man presented with progressive dyspnea due to severe isolated regurgitation of a 29-mm ATS 3f stentless (model 1000) aortic bioprosthesis. Because of his advanced age and multiple severe comorbidities, the Heart Team opted for a valve-in-valve transcatheter aortic valve replacement (TAVR).
Case Summary:
Based on preprocedural computed tomography planning, a valve-in-valve TAVR procedure was successfully performed via transfemoral access using a 27-mm JenaValve Trilogy System.
Discussion:
Although the use of dedicated TAVR devices for the treatment of native aortic regurgitation has been well-described, to our knowledge, there are no existing reports on their use to address regurgitation caused by the structural valve deterioration of a stentless bioprosthesis.
Take-Home Message:
Consider a dedicated transcatheter valve to treat pure regurgitation in a failing stentless bioprosthesis.
