Bioprosthetic aortic valve failure occurs in approximately 50% to 60% of patients at 15 years after surgery. With the valve-in-valve procedure, a transcatheter aortic valve is implanted inside a bioprosthetic valve, allowing a patient to avoid repeat sternotomy.
In this video, preprocedural invasive simultaneous left ventricular and aortic pressure tracings demonstrate an elevated transvalvular gradient consistent with severe bioprosthetic aortic stenosis, and a baseline aortogram confirms a failing stenotic bioprosthetic aortic valve (arrowhead)(A).
Postprocedural simultaneous left ventricular and aortic pressure tracings and aortogram confirm a reduction in the transvalvular gradient and self-expanded transcatheter valve in previous surgical bioprosthetic valve (arrowhead) with no aortic regurgitation (B).
