An 80-year-old woman with a history of surgical aortic valve replacement with a 21 mm St. Jude Medical Biocorporcine aortic valve 14 years prior presented with New York Heart Association (NYHA) class III symptoms, severeaortic insufficiency from a degenerated prosthesis, and a large echocardiographic mobile mass representing a highlymobile prosthetic leaflet. The patient worsened to NYHA class IV symptoms despite medical management. The Societyof Thoracic Surgery mortality risk score was extremely high. However, a valve-in-valve transcatheter aortic valve replacement (TAVR) was found to be a reasonable option. We used a 20 mm SAPIEN 3 Ultra value (Edwards Lifesciences Inc., Irvine, CA, USA) with a SENTINEL embolic protection device (Boston Scientific, Marlborough, MA, USA). During valve deployment, the echocardiographic mobile mass was visually pinned between the new TAVR valve and the surgical bioprosthetic valve. No large embolic debris was noted within the embolic protection device, and the patient remained without any new focal neurologic deficits in the perioperative period and at the 30-day follow-up. The severe aortic insufficiency resolved, and the patient clinically improved to NYHA class II symptoms.
