Transcatheter aortic valve replacement
Transcatheter Aortic Valve Replacement (pronunciation: trans-kath-eh-ter aor-tic valve re-place-ment) is a minimally invasive surgical procedure that repairs the valve without removing the old, damaged valve. Instead, it wedges a replacement valve into the aortic valve's place.
Etymology
The term "Transcatheter Aortic Valve Replacement" is derived from the following components:
- Transcatheter - from the Latin trans meaning "across, beyond, through", and catheter which is derived from the Greek katheter meaning "something let down or put in."
- Aortic Valve - from the Greek aorte meaning "great artery" and the Latin valva meaning "a folding door, leaf of a folding door."
- Replacement - from the Latin re meaning "again" and placere meaning "to please, satisfy."
Procedure
The procedure is performed using a catheter inserted in the groin rather than opening up the chest and removing the damaged aortic valve. The new valve is inserted into the old valve's place through the catheter and once it's in place, the doctor will inflate a small balloon at the end of the catheter to help the new valve expand and fit into place.
