  • Simulation of TEE views, ICE views, and fluoroscopic rendering
  • Measurement and annotation tools
  • Reporting tools

TruPlan’s intended patient population is comprised of adult patients.

  • TruPlan should not be used for purposes other than those indicated in the indications for use.
  • TruPlan is not intended to perform a diagnosis, nor to replace any duties of the physician.
  • Measurements made in TruPlan should only provide additional information to, not replace, measurements made during the typical clinical workflow (e.g., intra-procedural imaging using fluoroscopy, TEE, and/or ICE)
  • The Fluoro, TEE, and ICE modules provide simulated, not real, images of fluoroscopic, TEE, and ICE views, respectively.
  • Quantitative analysis is dependent on the quality and correctness of the image source data (i.e, CT scans).
  • The TruPlan software may slow down when other software applications are being run on the same machine.
  • Operating system (OS) updates might require an updated version of TruPlan.
