ABSTRACT

Valve-in-valve procedures are likely to become increasingly frequent with the aging of the population and the increasing number of surgical bioprostheses implanted. More than 50% of these implanted valves have small diameters, which hinders the good expansion of transcatheter devices, leading to higher final gradients. Therefore, post-dilation is required to optimize implantation of the new device. Compliant balloons have limitations and a higher potential to rupture when used for this purpose. We describe a case of a valve-in-valve procedure using a non-compliant balloon for post-dilation of the implanted transcatheter device in a bioprosthesis with a small ring.
