24th Annual MUSC Update on Perfusion Conference
We are pleased to share that this year’s 24th Annual Update on Perfusion Conference is back and on-person! After last year’s virtual conference, we look forward to continuing the tradition of in-person conference networking, collaboration, and camaraderie. This year’s conference will be held from Thursday, October 27th to Saturday, October 29th, 2022. Participants can expect…
Read MoreECMO Implantation Training: Needle Penetration in 3D Printable Materials and Porcine Aorta
Shore A 10 and 20 polymers have similar needle penetration properties compared to the porcine tissue. Significantly more force is needed to pierce through the material fully. The most similar tested material to porcine aorta for needle penetration and piercing in ECMO-implantation is the silicon Shore A 10 polymer. This silicon could be a 3D-printable material in surgical training for ECMO-implantation.
Read MoreCardiac Surgery Simulation – Part II: Cannulation
Whereas a trainee has the opportunity to cannulate for cardiopulmonary bypass only once during a case, the trainee can utilize this simulation model to easily and faithfully practice each step hundreds of times to improve his or her technical skills and to be more prepared for the next case. We believe that practicing in this way can enhance intraoperative learning, performance, and confidence.
Read MoreA Computational Fluid Dynamics Study of the Extracorporeal Membrane Oxygenation-Failing Heart Circulation
Using an idealized geometry of the aorta and its major branches and a peripherally inserted return cannula terminating in the iliac artery, computational fluid dynamic simulations were performed to (1) quantify perfusion as function of relative ECMO flow and (2) describe the watershed region produced by the collision of antegrade flow from the heart and retrograde ECMO flow.
Read MoreEvaluation of Recirculation During Venovenous Extracorporeal Membrane Oxygenation Using Computational Fluid Dynamics Incorporating Fluid-Structure Interaction
We have developed a finite element computational fluid dynamics model incorporating fluid-structure interaction (FSI) that incorporates atrial deformation during atrial filling and emptying, with fluid flow solved using large eddy simulation. With this model, we have evaluated an extensive number of factors that could influence recirculation during two-site VV ECMO, and characterized their impact on recirculation, including cannula construction, insertion depth and orientation, VV ECMO configuration, circuit blood flow, and changes in volume, venous return, heart rate, and blood viscosity.

The game was found useable and satisfying. Further studies will analyze its effectiveness in cardiovascular perfusion education.
Read MoreComparison of A Perfusion Simulator to A Clinical Operating Room: Evaluation of Eye Tracking Data and Subjective Perception. A Pilot Study
The use of the simulator for (advanced) training is accepted and explicitly requested by perfusionists. Yet further research is needed to identify the decisive factors (like simulation duration or additional tasks) for a valid execution in the simulator. Furthermore, a larger sample size should be regarded to allow statistical analysis.

PPK modelling with simulation may be valuable for devising a cefazolin prophylaxis protocol for patients undergoing cardiac surgery with CPB.

Multimodal assessment using cognitive, technical, and motion analysis of basic CPB tasks using a high-fidelity simulation environment is a valid system to measure performance and discriminate experts from trainees.

We demonstrate a simple and cost effective, yet powerful, “in-vitro” ECCO2R model that can be used as an alternative to animal experiments for many research scenarios.

The new IABP module is easy to manage and can be used as a training tool in a clinical setting. Although based on literature data, the outcome of the simulations is encouraging. Additional work is ongoing with a view to further validate its features.
