Abstract
Advanced surgical procedures for congenital heart diseases (CHDs) require precise planning before the surgeries. The conventional approach for planning complex cardiovascular surgeries involves extracting the patients’ anatomical data through medical imaging, reconstructing heart models based on processed data, and 3D printing and cutting physical heart models. However, not only is 3D printing a time and resource intensive process, but such cuts are permanent, making it impossible to interactively experiment with different cuts with the same model. To enhance the surgical plan- ning experience, in collaboration with Children’s Healthcare of At- lanta (CHOA) Heart Center, I lead the development of CardiacAR, an iOS application that enables interactive surgical planning on mobile devices through augmented reality (AR). CardiacAR offers powerful and flexible tools critical for surgical planning, such as enhanced viewing of the 3D heart models in realistic environments, omni-directional slicing of the models, and virtual annotation. A usability evaluation with 6 medical experts was conducted to validate the effectiveness and usability of the application. The portability of iOS devices helps broaden access to the CardiacAR technology and streamline its deployment. CardiacAR is open-source and publicly available at https://github.com/poloclub/CardiacAR.
