摘要

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.
