ABSTRACT
Objective To assess the accuracy of three-dimensional color Doppler echocardiography (3DCDE) for measuring left ventricular stroke volume (LVSV). Methods A total of 45 patients were studied to measure LVSV by 3DCDE and two-dimensional Doppler echocardiograph(2DDE). Full-volume three-dimensional echocardiography (3DE) was also performed to measure left ventricular end systolic (LVESV) ,end diastolic(LVEDV) ,and LVSV (LVEDV-LVESV), which served as a reference standard for comparison. Results Mean values of LVSV by 3DE,2DDE,3DCDE were (79. 3 ± 22. 6)ml, (74. 0 ± 20. 6) ml,(78. 7 ±22. 6)ml. respectively. Compared with LVSV by 3DE,the correlation was excellent for 3DCDE (r = 0.96), good for 2DDE ( r =0.89). Conclusions LVSV measurement by 3DCDE is reasonably accurate. This new technology may be a valuable clinical tool for assessing cardiac function.
