Cardiovascular

Echocardiography


We can do something about heart failure. Ultrasound is making a real difference.

 

  • In early detection. Before the onset of severe clinical symptoms, ultrasound helps you:
    • Assess and quantify intraventricular dyssynchrony and dyssynchronous wall motion
  • In CRT (cardiac resynchronization therapy) and ICD (implantable cardioverter defibrillator) therapy. Ultrasound helps you:
    • Identify patients most likely to benefit
    • Optimize pacing parameters
    • Determine potential placement locations
    • Monitor post-placement cardiac function

 

Helping you turn the tide
Now you can do even more for your patients. Cardiologists have guided the development of Philips iE33, our comprehensive cardiac ultrasound solution - and it shows.

 

The iE33 now helps you evaluate patients in every stage of heart failure more quickly, more accurately.

 

Revolutionary 2D and 3D image quality and a powerful feature set of advanced quantification tools set this system apart from the rest.

 

PureWave technology for 2D
At the heart of PureWave is pure, uniform piezocrystal - the biggest breakthrough in transducer material in forty years. Significantly superior acoustic properties – as compared to traditional ceramic PZT (lead zirconate and titanate polycrystalline compound) – and exclusively ours.

 

The result?

  • Image quality improvement that’s instantly apparent - greater sensitivity accounts for the remarkable improvement
  • The same great performance on every patient – due to an extremely broad frequency range
  • Ideal for patients “technically difficult to image” – the broader bandwidth provides better penetration and greater harmonic imaging sensitivity
  • Award-winning technology – rated in the “Top 100” by R&D Magazine2

 

3D with a difference
The iE33 gives you both expanded 3D cardiac views and valuable data to help assess global function.

  • Based on high quality piezocrystal 2D images
  • Images reflect actual heart size – with no geometrical assumptions.

 

QLAB – a powerful quantification tool
QLAB has been validated3 as an accurate, efficacious aid in assessing cardiac function. This advanced software:

  • Calculates ejection fraction – in under a minute
  • Quantifies dyssynchrony
  • Compares multiple segments simultaneously – using the AHA 17-segment model1

 

Individually, these 3 features stand on their own, but their combination can offer you even more clinical value.

 

2D and 3D plus QLAB:

Advanced echo technology for CRT and ICD therapy
This advanced feature set makes the iE33 the logical choice for comprehensive assessment, planning, and post-procedural follow-up:

 


 

Pre-CRT Study

Pre-CRT regional volume waveforms and timing information indicate dyssynchronous LV segments.

  

 

Post-CRT Study

This Post-CRT study demonstrates improved synchronicity.

  • Strain Quantification – acknowledged as a vital functionality parameter – provides a way to analyze tissue motion (velocities) using 2D images to get specific segmental timing data
  • 3D Synchronicity Indices – provide synchronicity indicators
    • Values are assigned to the synchronicity of all segments
    • 3D looks at changes over time, helping you evaluate how segments change as they reach minimum volume
    • QLAB calculates whether segments reach minimum volume together - or not. Minimum volumes achieved at different times indicate dyssynchrony.

 

The iE33 combines exceptional image quality with essential quantification features in one powerful triage tool. With it, you can detect and assess the extent of heart failure in its earliest stages - at the point of care. You can also identify with increased confidence patients likely to benefit from CRT and ICD placement. With added information, device placement can be more effectively planned and post-procedural evaluation more easily conducted.
