Fluoroscopic identification of stented bioprostheses

TAVI within failing surgical aortic bioprostheses

Surgical aortic valve replacement remains the therapy of choice in the majority of patients with aortic stenosis. This section includes the device design along with its radiological/fluoroscopic appearance focussing on how this correlates with the implanted valve, as transcatheter aortic valve implantation is performed under fluoroscopic guidance.

Recognising the fluoroscopic appearance of a specific valve design, whether in providing a more complete understanding of the failing valve or in the choice and implantation for the valve-in-valve intervention itself, is a critical step in the overall success of the procedure.
