AngioAID 3D is educational tool designed to teach key concepts of diagnostic angiography of coronary arteries. Developed at the Mount Sinai Hospital in New York City, New York State's highest volume cardiac cath lab, we aim to provide an interactive learning experience on this important topic. Within a 3D live simulation, you begin by advancing a diagnostic guidewire into the aortic root. Then, advance one of many diagnostic catheter options to either the right of left coronary ostium. Through pushing and pulling, as well as rotation of the catheter, try to achieve a truly co-axial engagement of the coronary ostium with the catheter. Meanwhile monitor the hemodynamic tab which simulated damping from over-engagement or roofing of the catheter tip. Line up the view with the target view, zoom to fill the screen with he coronaries, and rotate the C-Arm LAO/RAO and Cranial/Caudal until you're where you think you need to be. Finally, inject dye and take a cine to compare with the one we actually did in the cath lab for this set of coronaries. In addition to the diagnostic simulation, "Review Mode" allows you to play with angles and panning while always being able to see the vessels with no dye injection needed. Also a collection of key topics have been included within the review mode such as key angiographic angles depending on what you're aiming to see clearly, vessel segmentation conventions, and more coronary anatomy and angiography pearls. We highly recommend you view the tutorial video that is available when you first open the application or from the settings page to understand all of the available functions. The first launch has a normal set of coronary arteries but please stay tuned while we create more sets of coronaries such as anomalous coronaries and bypass grafts.

Verdict

The call

The clearest difference is price: AngioAID 3D at Free against ECGsource's $0.99. AngioAID 3D also leads on rating (4.0 vs 3.0). ECGsource's advantage is ads (none vs shown) and update cadence (every 4 months vs every 28 months). On in-app purchases and device support there is nothing between them.

AngioAID 3D is free to download; ECGsource costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

AngioAID 3D holds the better App Store score, 4.0 against 3.0. That said, the two scores are not equally well evidenced: ECGsource has 8 ratings behind it against 1, so its average is the more settled of the two.

UpkeepUpdate frequency

ECGsource ships an update every 4 months, AngioAID 3D every 28 months. The most recent releases landed on September 21, 2026 and September 25, 2026 respectively.
