Quantification of left and right ventricular function in patients with dilated cardiomyopathy using real-time three-dimensional echocardiography

Objective: To explore the value of real-time three-dimensional echocardiography( RT-3DE) in the evaluation of left and right ventricular systolic function in patients with dilated cardiomyopathy( DCM). Methods: Thirty five patients with DCM and forty healthy individuals were enrolled,by using RT-3DE with Philips IE33 color doppler ultrasonic diagnostic apparatus to measure left and right ventricular systolic function parameters and analyze the possible correlation of left ventricular and right ventricular functions. Results: The results of EDV and ESV were significantly higher in patient group with DCM than those in the control group( P 0. 01). The result of EF was significantly lower in patients with DCM than in the control group( P 0. 01),the correlation analysis results of LVEF and RVEF measured by RT-3DE in patients with DCM were positively corrected( r = 0. 59,P 0. 01). Conclusions: RT-3DE can accurately assess of ventricular systolic function in patients with DCM by measuring the left and right ventricular systolic function parameters. Left ventricular systolic function had a positive relation with right ventricular systolic function in patients with DCM and indicates that there is a positive relation between the degree of impaired left and right ventricular systolic function.
