Cardiac surgery has unique challenges that stem from the rarity and complexity of cases, as well as limited training opportunities due to time constraints and regulatory factors. Beating-heart simulators offer a visionary solution, enabling cardiac surgeons to practice rare and intricate procedures in a risk-free environment, ultimately transforming the way surgical skills are honed and expertise is developed. However, cardiac simulations are algorithmically challenging and computationally expensive.
Heart simulations naturally involve complex tasks such as mesh refinement, preconditioning, optimization, and parallelization. The major challenges of cardiac simulations consist in discretizing space and time, characterizing initial and boundary conditions, and accurate modeling the large deformations associated with the contraction and relaxation of the heart.
ALAFIA AIVAS Supercomputer on display at the Consumer Technology Association's CES 2025 Innovation Awards Showcase area, in the Venetian Expo, Hall A Booth #50043 demonstrates an anatomically accurate cardiac simulation sample application developed by Qt Group. The application showcases a 3D simulated heart which can be configured to beat at different rates by adjusting a beats-per-minute (BPM) slider or clicking the "PULSE RATE" toggle buttons. The heart can also be resized with the size slider or through the "MAGNIFICATION" buttons. With anatomically accurate call-outs available for educational purposes, when enabled, will label various aspects of the heart 3D model. Physicians would also have the ability to add open-ended notes by clicking on the drop-down menu at the top right of the application.
