Expanding indication and use of Transcatheter aortic valve replacement (TAVR) poses a unique problem of coronary access after valve implantation. Even though troubleshooting tools and techniques have been published, these are not available at the fingertips of the user at all the times. We tried to address this unique problem with an innovative educational mobile application (app) called “TAVRcathAID.”


We extensively reviewed currently available peer-reviewed literature, reference books and online learning resources for coronary access after TAVR and developed an algorithm (Figure 1) for app development. We utilized transparent aortic root model with transcatheter aortic valve in place to explain 3D applied anatomy and guide-wire/guide-catheter interaction with this complex anatomy. These videos were further used to develop 3D animation models for the application.


We found that most educational resources rely on wordy explanations, illustrations and fluoroscopic images, but none offers any interactive experience with users. We created new teaching styles which utilize the unique interactive features of smartphone technologies to aid experiential learning.


Our mobile app TAVRcathAID utilizes adoption of innovative teaching styles via smartphone technologies to offer interactive and realistic learning of complex cardiovascular concepts.
