Area of Science:

  • Cardiology
  • Echocardiography
  • Cardiac Function Assessment

Background:

  • Left ventricular ejection fraction (LVEF) is crucial for assessing systolic function and predicting cardiovascular mortality.
  • Echocardiography is the primary clinical tool for LVEF assessment.
  • The American Society of Echocardiography recommends the Simpson biplane multiple disc method (BMDM).

Purpose of the Study:

  • To evaluate the accuracy and reproducibility of Dumesnil's method for LVEF measurement.
  • To compare Dumesnil's method with the standard BMDM in a clinical setting.

Main Methods:

  • Prospective study involving 100 patients undergoing coronarography.
  • LVEF measurements performed using both BMDM and Dumesnil's method.
  • Left ventricular angiography served as the reference standard.

Main Results:

  • Dumesnil's method showed a correlation coefficient of r=0.85 with LV angiography, while BMDM achieved r=0.9.
  • In patients with regional asynergy, correlations were r=0.69 for Dumesnil's method and r=0.85 for BMDM.
  • Both methods demonstrated low intraobserver and interobserver variability (<7%).

Conclusions:

  • Dumesnil's method is simpler and faster than BMDM for LVEF assessment.
  • While less accurate than BMDM, Dumesnil's method offers satisfactory reliability and reproducibility.
  • Dumesnil's method presents a viable alternative for LVEF estimation in clinical practice.
