Area of Science:

  • Cardiology
  • Pulmonary Medicine
  • Diagnostic Imaging

Background:

  • Exercise echocardiography is a valuable tool for assessing cardiac function.
  • Doppler echocardiography aids in evaluating ventricular function, valve performance, and pressures.

Purpose of the Study:

  • To review the utility of agitated saline-enhanced Doppler of tricuspid insufficiency.
  • To determine pulmonary artery pressure during exercise in chronic lung disease.

Main Methods:

  • Utilized exercise echocardiography with two-dimensional imaging and Doppler.
  • Employed agitated saline contrast for tricuspid insufficiency assessment.
  • Monitored pulmonary artery pressure throughout exercise.

Main Results:
