Reproducibility of left ventricular mass measurements by two-dimensional and M-mode echocardiography.
Both two-dimensional and M-mode echocardiography provide accurate estimates of left ventricular mass. However, their reproducibility in serial studies has not been compared, although this issue is critical to evaluation of regression of hypertrophy. To determine which technique provides more reproducible estimates of left ventricular mass, three serial studies were performed prospectively in ea...
متن کاملCanine left ventricular mass estimation by two-dimensional echocardiography.
This study was designed to develop a two-dimensional echocardiographic method of measuring the mass of the left ventricle. The general formula for an ellipse was used to derive an algorithm that described the shell volume of concentric truncated ellipsoids. In 10 canine left ventricular two-dimensional echocardiograms, this algorithm accurately predicted postmortem left ventricular mass (r = .9...
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 کاملInfluence of measurement inaccuracies on determination of left ventricular mass by M mode echocardiography.
OBJECTIVE To determine to what extent inaccuracies in measuring the end diastolic diameter of the left ventricle, the interventricular septum, and the posterior wall, by M mode echocardiography influence the left ventricular mass calculated by the Devereux's formula. DESIGN Mathematical model. RESULTS Relatively small measurement inaccuracies such as 5%, which are known to be inherent in th...
متن کاملDiagnosis of left ventricular thrombi by two-dimensional echocardiography.
Sixteen patients had two-dimensional echocardiographic diagnosis of the presence or absence of left ventricular thrombi and anatomical, radiological, or clinical confirmation of the diagnosis. Eleven patients had positive diagnoses, which were confirmed in 10 and possibly incorrect in one. Five other records were reviewed because the patients had undergone aneurysmectomy after two-dimensional e...
