Anatomy Study

  • Virtual anatomy data was used for comparison of animal anatomy to human anatomy prior to in vivo trials of the Realheart TAH
  • With the virtual analysis it was possible to determine the spatial constraints of the target anatomy, such as vessel position and orientation, shape and space

Virtual Fitting

SJ Sonntag et al. Virtual Implantations to Transition from Pig to Calf Animal Models for a Total Artificial Heart, Artificial Organs 2019
  • Virtual fitting was used to re-design the outer dimensions and vessel connections of the Realheart TAH to transition from the porcine to the bovine animal model
  • Virtual implantations in combination with calf cadaver studies enabled a series of successful acute calf implantations and further improved the implantation technique

Working with Virtonomy helped speed up preparations for last year’s calf operations. Virtual operations before real operations save both time and money, not least because it is now possible to reuse virtual models for other researchers around the world. And at the same time, it feels right in time to support more sustainable development in the research world and to contribute to the need for fewer laboratory animals.

”We really enjoy working with Virtonomy. They are experts in virtual implantations and have been a tremendous resource in helping us to adapt our device to the anatomies of humans and large animals. We are looking forward to continuing our collaboration!“

Dr. Ina Laura Pieper, Chief Scientific Officer, Scandinavian Real Heart AB

Pre-Operative Planning

  • Patient required implantation of Evaheart 2 heart assist device (Evaheart Inc., Sun Medical Technology Corp.)
  • Challenging clinical case with small body size and thin torso (BSA 1.42), surgeon was not sure whether the patient’s anatomy allows to do it
  • Anatomical fitting simulation showed feasibility of the implantation

”We encountered a challenging clinical case with small body size and thin torso, who required implantation of our heart assist device. Surgeon was so nervous whether the patient’s anatomy allows to do it. Simon quickly implemented the pre-operative patient 3D data and provided us a fitting simulation. All of the works are flawless and done in timely manner, and the surgery was so successful! We satisfied the peace of mind with the pre-operative analysis, which was eventually validated with “post-operative” image as well.“
