Imaging findings
Baseline imaging showed a bioprosthetic aortic valve with functional impairment (stenosis and incompetence). Post-procedural imaging, including fluoroscopy and radiographs, demonstrated a CoreValve prosthesis successfully deployed within the failing bioprosthetic valve in a "valve-in-valve" fashion. The CoreValve structure was visible within the older prosthesis.
Key takeaways
Transcatheter aortic valve replacement (TAVR) with devices like the CoreValve prosthesis offers a viable option for treating failing bioprosthetic aortic valves (stenosis or incompetence) via a valve-in-valve procedure, avoiding repeat open-heart surgery. Familiarity with the appearance of these devices on imaging is increasingly important.
