TTE FOCUS Views
This application aids in learning and teaching cardiac function assessment using Focused Cardiac Ultrasound (FOCUS) techniques. It provides interactive 3D models and TTE recordings for key cardiac views, allowing users to visualize probe placement and heart structures.
- Interactive 3D heart models
- TTE recordings for 5 FOCUS views
- 3D probe and ultrasound plane visualization
- Rotatable heart and rib cage models
- Ability to remove rib cage and heart sections
- Focus on pericardial abnormalities

In the practice of anesthesia, critical care and emergency medicine there is often a need for a quick, qualitative assessment of cardiac function. Focused Cardiac Ultrasound (FOCUS) is the process of carrying out this rapid qualitative assessment by practitioners in these fields. Training for carrying out a FOCUS assessment requires practitioners to understand the 3D structures of the heart that are seen in the 2D transthoracic echocardiography (TTE) image. We have created this interactive application to assist with teaching and learning the assessment of normal and pathologic cardiac function with FOCUS. FOCUS assessments are based on a subset of 5 of the 20 standard TTE views: Parasternal long axis Parasternal short axis Apical four chamber Subcostal four chamber Subcostal inferior vena cava Users can view the TTE recordings for each of the 5 FOCUS views and see a corresponding 3D model of the probe, ultrasound plane, heart and rib cage for each view. Each FOCUS 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 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. This module reviews the use of FOCUS to assess pericardial abnormalities of localised effusion and tamponade and their effect on cardiac function. *NOTE: This app has not yet been updated to include the right ventricle, left ventricle and hypovolemic pathologies found on the website. http://pie.med.utoronto.ca/TTE/TTE_content/focus.html

Verdict
The clearest difference is price: EchoRef at Free against TTE FOCUS Views's $4.99. EchoRef also leads on rating (4.9 vs 3.0) and update cadence (every 2 months vs every 24 months). TTE FOCUS Views's advantage is iOS requirement (6.0 vs 26.0). On ads, in-app purchases and device support there is nothing between them.
