Procedure for measuring the Aortic valve gradient through a single arterial access using the Abbott Pressure wire.
Warning: DO NOT have FFR unit turned on or it will confuse the wire transmitter!!!!!
Equipment
- St. Jude pressure receiver
Open
- Abbott pressure wire
- Catheter (MD choice)
- Intervention kit (You need, at minimum, a co-pilot and introducer needle)
- Second transducer (ACIST or manifold)
Procedure
- St. Jude box should be plugged into P2 or P3
- Cross aortic valve
- Prep pressure wire so it is flushed and flat on the table
- Press middle button on St. Jude receiver box
- Turn on wire transmitter
- Both lights should turn solid green
- Introduce wire into LV
- Use plus and minus arrows on receiver box to adjust wire pressure reading to match catheter.
- Note that waveforms will not match, but numbers should.
- Snap a gradient while both wire and catheter are in LV to confirm calibration if desired.
- Pull catheter back across aortic valve
- Snap gradient
