Cardiac Output Measurement With Echocardiography and Pressure Recording Analytical Method in Pediatric Patients Admitted to the Cardiac Intensive Care Unit: A Retrospective Assessment of Bias Between the Two Methods
2021, Journal of Cardiothoracic and Vascular AnesthesiaComparison of Cardiac Output of Both 2-Dimensional and 3-Dimensional Transesophageal Echocardiography With Transpulmonary Thermodilution During Cardiac Surgery
2020, Journal of Cardiothoracic and Vascular AnesthesiaCitation Excerpt :Estimation of cardiac output with TEE was first reported9,13 using the left ventricular outflow tract diameter to estimate the left ventricular outflow tract area and then multiplying by the velocity time integral at that point in the left ventricular outflow tract. Some examples of other cardiac structures used include the right ventricular outflow tract,27 left ventricle,28 pulmonary artery,29 ascending aorta,30,31 and mitral valve.32,33 Current recommendations for measuring the left ventricular outflow tract velocity time integral from the American Society of Echocardiography34 describe tracing the spectral Doppler envelope at the instantaneous dense modal velocities throughout systole.
Validation study of the accuracy of echocardiographic measurements of systemic blood flow volume in newborn infants
2013, Journal of the American Society of EchocardiographyCitation Excerpt :LVO and SVC flow volume as assessed by PC MRI had scan-rescan RIs (equivalent to the 95% confidence interval) of 11.5% and 12.8%, respectively.11 In the absence of any true gold standard, and acknowledging that all other “gold standards” such as the Fick method and thermodilution, also have intrinsic variability,28,29 we feel that PC MRI is the best comparator currently available for the validation of echocardiographic findings in this population. Our findings broadly support the use of echocardiographic assessments of LVO, which appear to be performed with a relatively high degree of accuracy.
Planimetry of the aortic valve orifice area: Comparison of multislice spiral computed tomography and magnetic resonance imaging
2011, European Journal of RadiologyPlanimetry of mitral valve stenosis by magnetic resonance imaging
2005, Journal of the American College of CardiologyCitation Excerpt :In routine clinical practice, both CATH and ECHO are used to assess MS. Cardiac catheterization is widely accepted as the gold standard, and MVA is calculated by the Gorlin formula from the mean transvalvular gradient and valvular flow (6). Because of the indirect measurements, however, the accuracy of MVA calculation has often been challenged (9,10). Despite these limitations, the Gorlin formula remains the standard criterion against which new noninvasive methods must be judged.
