Background:
Transcatheter aortic valve explantation is the fastest-growing cardiac operation in the United States, yet optimal techniques are not well-defined.
Case Presentation:
Here, we present a case of explantation of a self-expanding CoreValve Evolut PRO valve (Medtronic, Minneapolis, Minnesota).
Conclusions:
This report demonstrates a reproducible technique that leverages the temperature-dependent properties of nitinol to facilitate safe surgical explantation of self-expanding transcatheter aortic valves.
