Echocardiography training reduced Swan-Ganz catheter use, enabling new quantitative methods. Advanced signal processing allows non-invasive cardiac output and blood volume measurements using echocardiography contrast.

Area of Science:

  • Cardiology
  • Anesthesiology
  • Intensive Care Medicine
  • Medical Imaging

Background:

  • The Catharina Hospital previously used over 2200 Swan-Ganz catheters annually.
  • Training anesthesiologists in echocardiography (ECHO) significantly decreased the need for these invasive catheters.
  • Acquisition of dedicated ECHO machines further reduced reliance on Swan-Ganz catheters.

Purpose of the Study:

  • To develop non-invasive methods for quantifying cardiac function and hemodynamics.
  • To leverage indicator-dilution principles with echocardiographic contrast agents.
  • To establish advanced signal processing techniques for quantitative analysis.

Main Methods:

  • Development of algorithms using advanced signal processing and modeling.

  • Application of indicator-dilution principles to injected echo contrast.
  • Utilizing transesophageal echocardiography for data acquisition.

    • Main Results:

    • Successful quantification of intrapulmonary blood volume.
    • Accurate measurement of ejection fraction.
    • Reliable assessment of cardiac flow from transesophageal echocardiography data.

    Conclusions:

    • Quantitative echocardiography measurements can be performed on an outpatient basis.
    • These novel quantitative methods offer significant potential in cardiology, anesthesiology, and intensive care.
    • This approach provides a valuable alternative to invasive hemodynamic monitoring.
