02 / MITRAL INTERVENTION

Plan mitral valve procedures from CT.

QuanMitral measures the mitral valve and nearby anatomy on CT. Review the annulus, leaflets, and LV outflow tract, compare device positions, and plan an access route.

Curved LVOT and CT–echo fusion are still being tested.

THE WORKFLOW

How the workflow works.

  1. 01Cardiac phase
  2. 02Annulus & leaflets
  3. 03LVOT assessment
  4. 04Device position
  5. 05Access & views
  6. 06Report

Review the scan and measurements at each step.

01Annulus tracingMitral Intervention

Trace the mitral annulus.

Trace and review the mitral annulus across CT views. Confirm the contour before measuring its shape and dimensions.

02Annulus measurementsMitral Intervention

Measure annular geometry.

Review D-shape and saddle geometry, projected area, perimeter, intercommissural and septal-lateral dimensions, and phase-specific chamber volumes.

QuanMitral · annular geometry, dimensions, and chamber volumes
03Neo-LVOT assessmentMitral Intervention

Neo-LVOT assessment.

Choose a virtual valve size and position, confirm the LVOT axis, and review the predicted neo-LVOT area at different depths.

04Device recommendationMitral Intervention

Compare device options.

Compare options for the selected procedure. Review device size, annular fit, calcium, and neo-LVOT results when simulated. The cards follow measured values and flag reasons an option may not fit.

05DeploySIMGeometric deployment simulation

Simulate device deployment.

Preview how the selected frame opens within the measured annulus. Review its position and geometric neo-LVOT sweep. This kinematic animation does not model frame deformation or leaflet displacement.

06Leaflets & TEERMitral Intervention

Leaflets & TEER.

Review leaflet length, movement, and where the leaflets meet. For TEER, inspect the leaflet segments used in the plan.

07MAC & adjacent structuresMitral Intervention

MAC & adjacent structures.

Review calcium around the annulus and its distance from the septum and circumflex artery.

08Transseptal & transapical accessMitral Intervention

Transseptal & transapical access.

Review the fossa outline and suggested puncture point. Check its height above the annulus, alignment with the target axis, and the planned sheath path before confirming the site.

09MitralAssistProcedural view planning

Plan and review working views.

Generate CT-based TEE-like views for standard angles and adjust the planned probe depth, rotation, flex, and multiplane angle. The probe course is estimated, so depths are approximate and some poses may not be reachable in a patient. These are simulated CT views, not live ultrasound.

10Phase comparison & reportingMitral Intervention

Phase comparison & reporting.

Compare measurements across cardiac phases. Add the anatomy, device, and access measurements to the report.
