Abstract:
An 86‐year‐old lady with recurrent admissions for heart failure due to a severely regurgitant aortic bioprosthesis (SJM Epic 19 mm) was not a candidate for re‐operation due to age and frailty. Her small ilio‐femoral arteries precluded a transfemoral transcatheter valve‐in‐valve (VIV) approach. The small internal diameter of her bioprosthesis (16 mm) forbids the implantation of the smallest available transapical transcatheter heart valve (THV). We, therefore, decided to perform a first‐in‐human transapical aortic VIV implantation using a 20 mm balloon expandable THV and a transfemoral delivery system. The procedure was successfully performed under general anesthesia, without any contrast dye and under fluoroscopy as well as transesophageal echocardiography guidance. The post‐procedural transvalvular gradient was 15 mm Hg (pre‐procedural 14 mm Hg). At 30‐day follow‐up, the lady was living independently at home without shortness of breath during her daily activities. If redo‐surgery for prosthetic regurgitation is not an option, VIV implantation in very small surgical bioprosthesis is feasible and leads to acceptable hemodynamics and clinical improvement.© 2012 Wiley Periodicals, Inc.
