About

TEE Colour Doppler

This medical app visualizes cardiac blood flow using 2D and 3D color Doppler imaging. It aids in diagnosing and quantifying the severity of cardiac lesions by demonstrating normal flow patterns across heart structures.

Highlights
  • 2D and 3D echocardiography visualization
  • Color Doppler imaging for blood flow assessment
  • Rotatable 3D heart models
  • Color compare video clips
  • Demonstrates normal blood flow patterns
Read full description

Two and three-dimensional echocardiography forms the basis of assessing cardiac structure and function. The application of colour Doppler imaging is routinely performed over cardiac valves, vascular and other pathological structures to assess blood flow direction and velocity. This aids the confirmation of pathological diagnoses and quantifies the severity of these lesions. This module demonstrates which structures should be viewed using colour Doppler during the standard 2D examination. Each of the 20 standard views is accompanied by a rotatable three-dimensional heart model and a `colour compare’ video clip which simultaneously shows the two-dimensional and colour Doppler images of each view. Normal blood flow across or within various parts of the heart is shown.

Verdict

The call

The clearest difference is price: iPacemaker Device at Free against TEE Colour Doppler's $4.99. iPacemaker Device also leads on rating (4.7 vs 3.0) and update cadence (every 4 days vs every 24 months). TEE Colour Doppler's advantage is in-app purchases (none vs 7) and iOS requirement (6.0 vs 17.6). On ads and device support there is nothing between them.
