Abstract [en]

Objectives: To study the correlation of the aortic-, mitral-, and tricuspid annuli and their amplitudes and velocities with the left ventricular stroke volume (LVSV) in young healthy subjects at rest using echocardiography.

Methods: Twenty four healthy subjects with mean age 24 years were examined with echocardiography. The systolic, early and late diastolic velocities of the aortic-, mitral- and tricuspid annuli were measured with pulsed wave tissue Doppler and quantitative two-dimensional color Doppler tissue imaging as well as their amplitudes.

Results: There was only one significant correlation found between the measured parameters and LVSV, a finding that can be statistically random. All other correlations were not significant.

Conclusion: In young healthy individuals at rest the correlation between the amplitudes and velocities of the aortic-, mitral- and tricuspid annuli and LVSV is weak.
