CT TAVI Planning

Pre-procedural planning is essential

Crucial for a successful TAVI procedure is an accurate pre-procedural planning based on which the access path for the catheter and the device type and size can be determined.


SOMATOM Definition Flash and syngo.via
A powerful solution for safer TAVI procedures

With its Flash Spiral the SOMATOM Definition Flash allows to acquire the relevant anatomy in a single scan – with a ground breaking low contrast agent dose of 40 ml only.1
The key to successful planning is a reliable assessment of the aorta. With syngo.via’s CT TAVI Planning a streamlined and accurate assessment of all parameters is now possible in one dedicated workflow.

CT TAVI Planning

Single-scan acquisition with the SOMATOM Definition Flash

With its high-pitch spiral the SOMATOM Definition Flash allows to acquire the aortic root, aorta and iliac arteries in a single scan and with one contrast injection only. A pitch value of 3.2 yields scan times of less than 2 s for a scan range of up to 65 cm. Due to the short scan time the amount of contrast agent can be reduced to a minimum of 40 ml only.1
 

Customer experience

At Aarhus University Hospital, Skejby, Denmark, several TAVI procedures are performed each month. The regular use of the Flash Spiral helps to keep contrast agent dose minimal.

Valve Pilot

CT TAVI Planning for accurate assessment of all parameters

The CT Cardio-Vascular Engine offers a dedicated workflow for CT TAVI Planning. As an optional extension syngo.CT Cardiac Function – Valve Pilot helps save time as well as making your planning results more precise. Together they allow for:

  • single-click localization and quantification of the smallest iliac diameter
  • visualization and subtraction of aortic calcifications based on single energy data
  • easy assessment of the curvature of the aortic arch
  • straightforward evaluation of LVOT, sinotubular junction etc.
  • automatic calculation of corresponding angulation for a given projection
  • zero-click display and zero-delay quantitative assessment of the aortic annulus
  • calculation of annulus short and long axis as well as effective diameters as the case is opened
  • two ostia views for a faster assessment of their distance to the annulus plane

Customer experience

The University of Erlangen-Nuremberg performs roughly 10-15 TAVI procedures a month. Here, the workflow CT TAVI Planning brings more efficiency into clinical routine.

CT TAVI Planning

Automated transfer of predicted angulation

As part of the CT TAVI Planning workflow the application syngo.CT Cardiac Function automatically predicts the corresponding C-arm angulation for a given projection. Once the optimal projection is determined the angulation may be transferred directly to the cath lab to help save time and contrast agent dose.2
