TAVR planning

Plan TAVR from CT.

QuanTAVI measures aortic anatomy on CT, compares valve sizes and positions, and prepares views for TAVR. After the procedure, CT can be used to review the implanted valve.

Auto annulus Measurements Valve options Bicuspid Simulation Prediction Lifetime planning Compare plans Report TAVIAssist Expansion review Post-TAVR analysis
01Auto annulusBefore TAVR

Set the annular plane.

Mark the cusp attachment points on CT, then check and adjust the annular plane.

  • View the annulus on CT
  • Adjust the landmarks when needed
  • Review the selected cardiac phase
02MeasurementsBefore TAVR

Measure the aortic root.

Measure the annulus, LVOT, sinuses, and sinotubular junction. Review the measurements across selected cardiac phases.

  • Review each measurement on the CT images
  • Compare measurements across phases
  • Keep measurements with the procedure plan
03Valve optionsBefore TAVR

Compare valve sizes.

Compare available valve sizes against the measured annulus and surrounding anatomy.

  • Review the listed size options
  • Compare each option against the CT
  • Check coronary height and calcium around the annulus
  • Review the measurements behind each option
04Bicuspid anatomyBefore TAVR

Review bicuspid anatomy.

Review the valve shape and annular landmarks, including the Type 0 workflow.

  • Review the valve and raphe on CT
  • Set landmarks for the measured anatomy
  • Check measurements after changing landmarks
05Valve placementBefore TAVR

View the planned valve position.

Place a virtual valve in the measured anatomy and review its depth and orientation.

  • Adjust the planned depth and angle
  • Review the valve beside the CT anatomy
  • Save and compare placement options
06PredictionFEA simulation

Predict valve expansion and assess potential complications.

The simulation models how the valve may expand and interact with surrounding anatomy. Review the predicted frame shape and contact areas to assess potential complications.

  • Review predicted valve expansion and frame shape
  • Inspect contact with surrounding anatomy
  • Review potential complications indicated by the simulation
  • Compare simulated placement options
07Lifetime planningBefore first TAVR

Plan today’s TAVR with the next one in mind.

Review how the initial valve choice and position may affect future redo TAVR. This can help keep another TAVR an option where anatomy permits.

  • Review valve choice and planned position
  • Consider future valve-in-valve placement
  • Check how the plan may affect future coronary access
  • Keep these considerations with the case plan
08Compare plansBefore TAVR

Compare placement options.

Change the valve, size, depth, or angle and review how each plan compares.

  • Review the inputs used for each option
  • Compare the displayed positions
  • Adjust the plan and review it again
09ReportBefore TAVR

Collect the plan in a report.

Bring the measurements, valve option, planned position, and review notes together for the case.

  • Review what is included
  • Check the source measurements and selected option
  • Save or export the report when available
10TAVIAssistDuring TAVR

Look up the plan by voice.

Use voice prompts to look up measurements and review the next step during the procedure.

  • Ask for a measurement from the plan
  • Review a planned valve position
  • Request the next listed step
11Expansion reviewAfter valve placement

Review the expanded valve.

Review the displayed frame shape and expansion after valve placement, then compare it with the plan.

  • Review frame expansion and shape
  • Compare the displayed result with the planned position
  • Keep findings with the case record
12Post-TAVR analysisAfter TAVR

Review the post-TAVR CT.

Compare the pre- and post-TAVR studies. When post-procedure CT is available, inspect the valve frame and review sinus and HALT measurements.

  • Compare pre- and post-TAVR CT views
  • Review valve-frame shape and expansion
  • Inspect sinus dimensions and calcium
  • Review HALT measurements when available
