Abstract

 BACKGROUND:
More dependence on real-time three dimensional echocardiography, is in practice in the assessment of LV
systolic function in coronary and valvular heart disease.
OBJECTIVE:
To investigate the accuracy of linear M-MODE and volumetric (BIPLANE and TRIPLANE)
echocardiographic method versus the REAL-TIME 3DE in assessment of regional and global LV systolic
function (depending on the high agreement of RT -3DE with CMR which is the gold standard in
assessment of LV systolic function) and to start orientation to this issue in our centers.
PATIENTS AND METHOD:
This study included 60 patients with coronary heart disease and valvular heart disease who were
admitted in Iraqi center for cardiac disease, for whom the LV systolic function is assessed by EF% by
using 3 methods which are M-mode, biplane, triplane methods and compare it with RT-3D
echocardiography.
RESULTS:
There is a significant difference between RT-3D echocardiography and old measures, (M-mode ,
sensitivity and specificity was 74.3% , 95.2% respectively) and that of (Biplane was 97.4%, 95.2%
respectively ), while there is no significant difference with triplane method in the assessment of LV
systolic dysfunction by EF% in coronary and valvular heart disease as it was (97.4% , 100% respectively)
CONCLUSION:
Real-time three dimensional echocardiography provides more valuable and accurate clinical information
that empowers echocardiographers with new levels of confidence in the diagnosis of LV systolic
dysfunction in coronary and valvular cardiac disease.
