Comparative Study
3D and 2D left ventricular systolic function imaging-- from ejection fraction to deformation. Cardiac resynchronization therapy--substudy.
3D echocardiography offers options of left ventricular systolic function analysis. The aims of this study are: to assess the usefulness of 3D echocardiography, to test 3D regional measurements (with area strain) among a spectrum of patients and then to check prospectively the value of 3D echocardiography vs 2D in the assessment of response to resynchronization. ⋯ 3D echocardiography is applicable in the assessment of both preserved and reduced left ventricular ejection fraction. This assessment is fast and requires minimal user intervention. 3D strain may help in cardiac resynchronization therapy candidates and response assessment. After cardiac resynchronization, none of the patients were incorrectly identified as responder to cardiac resynchronization therapy by 3D algorithms compared to 2D Simpson's reference.
