TTE Standard Views vs ECGRef
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
TTE Standard Views
This app aids in learning cardiac function assessment using transthoracic echocardiography. It provides interactive 3D models and TTE recordings for standard cardiology exam views, allowing users to visualize heart structures from any angle.
- Interactive 3D heart models
- TTE recordings for standard views
- Probe and ultrasound plane visualization
- 3D model rotation
- Rib cage removal option
- Heart model orientation

We have created this interactive application to assist with teaching and learning the assessment of cardiac function with transthoracic echocardiography (TTE). The primary challenge in learning TEE is translating the two dimensional echocardiographic image into a visualization of the three-dimensional (3D) structure of the heart. Users can view the TTE recordings for each of the 20 standard views used in a full cardiology exam and see the corresponding 3D model of the probe, ultrasound plane, heart and rib cage for that view. Each TTE view can be selected from a menu at the left of the screen, or by using arrow buttons to go to the next or previous view in the list. For each TTE view, the 3D model of the probe, ultrasound plane, heart and rib cage can be rotated in the horizontal or vertical plane to view it from any angle. The rib cage can be removed, the part of the heart above the echo plane can be removed, and the heart model can be oriented so the structures correspond to the TTE image.
