Proximal dislocation of a sutureless Perceval valve after the second aortic valve replacement.

ABSTRACT

Sutureless aortic valve replacement is a widely used technique that facilitates short cross-clamping time and has excellent hemodynamic outcomes. However, it is associated with paravalvular leakage or migration risk. We report a surgical case using a sutureless aortic valve replacement in a 74-year-old male patient with a history of previous aortic valve replacement. He underwent redo aortic valve replacement with the Perceval valve (Corcym Canada Corp, Vancouver, Canada), which got dislocated with moderate-to-severe aortic paravalvular leakage at 3 months after implantation. Our observations suggested that redo aortic valve replacement using a sutureless aortic valve can cause valve dislocation as it might be difficult to clearly remove calcification and excess tissue and implant the valve to crimp on the annulus precisely. This report also highlights the challenges of performing repeat aortic valve replacement after explanting the Perceval valve, which includes the aortotomy height and annulus identification. Although the Perceval valve can help improve patient prognosis, careful implantation and thorough follow-up examinations are warranted.
