It is recognized that the valve-in-valve procedure is technically challenging and requires appropriate case and device selection. Imaging plays a key role in all aspects of valve-in-valve implantation. Multidetector computed tomography (MDCT), echocardiography, and periprocedural angiography to evaluate the radiopaque surgical landmarks are all crucial for correct valve-in-valve sizing and positioning and thus, successful implantation. We will review imaging requirements for valve-in-valve implantation for failed surgical bioprostheses. Valve-in-valve implantation for failed or malpositioned transcatheter valves is a separate topic and not discussed.

Surgical Valves

Bioprosthetic surgical valves have consistent, reproducible leaflet kinetics as the leaflets are mounted in a rigid framework. The wide variety of surgical valves available can be broadly classified into stented and stentless devices (Tables 32.1 and 32.2). These groups have unique features that must be considered for valve-in-valve sizing and positioning. Conventional bioprosthetic valves incorporate bovine or porcine pericardium incorporated into a stent frame or stentless conduit.
