## What is TTE FOCUS Views?

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

## Frequently asked questions about TTE FOCUS Views

### What is TTE FOCUS Views used for?

TTE FOCUS Views is an interactive application designed to assist in teaching and learning the assessment of normal and pathological cardiac function with Focused Cardiac Ultrasound (FOCUS). It helps users understand the 3D structures of the heart as seen in 2D transthoracic echocardiography (TTE) images.

### What cardiac views are included in TTE FOCUS Views?

TTE FOCUS Views covers 5 key FOCUS views: Parasternal long axis, Parasternal short axis, Apical four chamber, Subcostal four chamber, and Subcostal inferior vena cava. These are a subset of standard TTE views used for rapid cardiac assessment.

### Can I interact with the 3D models in TTE FOCUS Views?

Yes, for each view, you can rotate the 3D model of the probe, ultrasound plane, heart, and rib cage in horizontal or vertical planes. You can also remove the rib cage or parts of the heart above the echo plane to better visualize structures.

### What pathologies does TTE FOCUS Views cover?

The current module reviews the use of FOCUS to assess pericardial abnormalities, specifically localized effusion and tamponade, and their effects on cardiac function. Note that it has not yet been updated to include pathologies of the right ventricle, left ventricle, and hypovolemic conditions.

### What devices is TTE FOCUS Views available on?

Based on the provided data, TTE FOCUS Views is currently supported on iPads. It is not listed as available for other devices like iPhones or Android tablets.
