INTRODUCTION
In patients with aortic stenosis, sutureless aortic valves are a relatively novel method of surgical aortic valve replacement (SAVR), and due to less potential invasive nature, these valves are increasingly preferred in patients with significant comorbidities. Likewise, transcatheter aortic valve implantation (TAVI) is a less invasive method of aortic valve replacement for patients with high surgical risk (1). An emerging and less invasive indication of TAVI is bioprosthetic valve failure instead of re-do surgical valve replacement (2). Although numerous reports and series of the successful valve in valve (VIV) procedures have been published in patients with failing stented or stentless bioprosthetic valves, so far, only one case report is present regarding the feasibility of aortic VIV procedures for failing sutureless aortic valves with a balloon-expandable transcatheter valve. In this report, we present a case of the trans-femoral implant of a self-expandable (Portico) aortic valve in a failing sutureless self-expandable Sorin Perceval® S valve.
