Abstract Objective: To investigate the correlation and concordance between dual source CT(DSCT) and echocardiography in the assessment of left ventricular function parameters. Methods: Seventy-nine patients who underwent DSCT coronary angiography and echocardiography were studied in two groups. Group 1 consisted of thirty-nine consecutive patients, who were enrolled with clinic proved chronic myocardial infarction(MI) and group 2 consisted 40 consecutive patients with no prior history of acute MI as control. All of them underwent echocardiography within a week. The correlation and concordance between DSCT and echocardiography in evaluating left ventricular ejection fraction(LVEF) and left ventricular fractional shortening(LVFS) was assessed. Results: Results of DSCT and echocardiography for LVEF had a good correlation and concordance for the two groups(control group r=0.751, and MI group r=0.718, P<0.01). There was median correlation between LVFS by using DSCT and echocardiography assessment LVFS(control group r=0.543, MI group r=0.606, P<0.01). Conclusion: DSCT coronary angiography can be used in diagnosing coronary lesions and in quantitative assessment of left ventricular function parameters simultaneously.
