CTICasesValve-in-Valve Transcatheter Aortic Valve Replacement (TAVR)
Imaging findings
Post-operative radiography and fluoroscopy show a self-expanding, transcatheter aortic valve (Medtronic Evolut CoreValve) deployed directly inside a pre-existing bioprosthetic aortic valve to correct bioprosthetic aortic stenosis.
Key takeaways
For patients with a failing, stenotic surgical aortic bioprosthesis, a valve-in-valve transcatheter aortic valve replacement (TAVR) is an effective minimally invasive alternative to a repeat open-heart sternotomy. It is crucial to recognize the characteristic nested radiographic appearance of a transcatheter heart valve within a surgical valve frame.
