Step 1: Connect the Verrata pressure wire
SyncVision will automatically switch to FFR/iFR display when either:
- Zeroing is performed.
- The pressure gradient (PD) is greater than 10.
Description of console display: Shows real-time physiological data including iFR (0.87), Pd/Pa (0.88), Pa (94), Pd (83), and HR (65), alongside corresponding pressure waveforms. Buttons visible include Freeze, Normalize, Pullback, Settings, Patient, and FFR.
Alternatively, you can switch manually to the FFR/iFR display.
Description of manual switch option: A button with a circular icon and a plus symbol, indicating manual selection of the FFR/iFR mode.
Step 2: Pullback
Perform continuous fluoroscopy (fluoro) during the pullback. Optimal frame rate is 15 PPS (Pulses Per Second); minimal is 7.5 PPS.
Description of fluoro image: A grayscale image showing a blood vessel.
On the Core console, press the [Pullback-button] button.
Description of console display: Shows the "Pullback" button highlighted.
A "Recording..." indication will appear on the console.
Description of console display: Shows the "Recording..." text prominently, indicating data capture is active.
Step 3: Angiogram for roadmap selection
Perform a new angiogram without changing the table, C-Arm, or patient position. Alternatively, use the last angiogram performed by clicking the "Use Last Angio" option.
Description of console display: Shows "iFR® Distal: 0.91" and a list of runs. Icons for [undo/cancel-icon] and [close-icon] are visible.
This step is part of the "Fully automated" co-registration process.
Description of console display: Shows "iFR Distal: 0.68" and "iFR at Cursor: 0.84".
Select the appropriate tab or option:
- [iFR Co-reg tab]
- [Manually define pathway]
Description of icons/buttons: Arrows point to specific interface elements labeled "iFR Co-reg tab" and "Manually define pathway", allowing selection of the co-registration method.
