Reproducibility of echocardiographic left ventricular measurements.
Serial echocardiograms with acceptable reproducibility of measurements may be produced by careful performance and interpretation of the studies. The following recommendations have been shown to enhance reproducibility. Strict adherence to quality control is necessary to generate echocardiograms of the highest technical quality. Sonographers should be aware of the definition of a technically ade...
متن کاملAccuracy and reproducibility of biplane two-dimensional echocardiographic measurements of left ventricular dimensions and function.
OBJECTIVE To investigate sources of variability in serial echocardiographic recordings in a core laboratory we assessed the impact of repeated echo recordings, repeated video measurements and measurements made by different investigators. PATIENTS, METHODS Two investigators each recorded and analysed two-dimensional echos in 12 individuals (n = 24 in total) three times at one week intervals. L...
متن کاملReproducibility and accuracy of echocardiographic measurements of left ventricular parameters using real-time three-dimensional echocardiography.
OBJECTIVES We sought to determine whether assessment of left ventricular (LV) function with real-time (RT) three-dimensional echocardiography (3DE) could reduce the variation of sequential LV measurements and provide greater accuracy than two-dimensional echocardiography (2DE). BACKGROUND Real-time 3DE has become feasible as a standard clinical tool, but its accuracy for LV assessment has not...
متن کاملReproducibility of echocardiographic estimates of left ventricular dimensions.
Although echocardiography is ideally suited for repetitive use on a patient for evaluation of left ventricular function, the value of this application is minimised by the uncertainty as to whether changes in left ventricular dimensions observed on a patient at different times or by different observers are real or result from the ultrasonic beam penetrating the left ventricle at different angles...
متن کاملThe reproducibility and absolute values of echocardiographic measurements of left ventricular size and function in children are algorithm dependent.
BACKGROUND Several quantification algorithms for measuring left ventricular (LV) size and function are used in clinical and research settings. The aims of this study were to investigate the effects of measurement algorithm and beat averaging on the reproducibility of measurements of the left ventricle and to assess the magnitude of agreement among the algorithms in children with dilated cardiom...
