“…As a result, the values of left atrial and left ventricular volumes were similar to those reported by others using echocardiographic and magnetic resonance imaging technique [31][32]. Although echocardiography has been found to underestimate cardiac volumes, good correlations between echocardiographic and angiographic measurements as well as between angiographic and autopsy measurements of left atrial volumes have been reported [32][33][34][35]. The intraobserver variation for left atrial volumes ranges from 4.9% ± 1.3% to 5.4 ± 1.8% and interobserver variation from 5.3% ± 1.6% to 5.9% ± 2.3% [18,19].…”

The aim of the paper was to investigate the right ventricle in paediatric dilated cardiomyopathy. We examined 11 patients with dilated cardiomyopathy as well as 12 normal paediatric controls. Cardiac magnetic resonance imaging was performed for ventricular size and function. N-terminal pro-brain natriuretic peptide was collected at this time and the results from the most recent echocardiogram and exercise test were reviewed.We found that patients with dilated cardiomyopathy had significantly faster heart rates, that is, 85 versus 65 beats per minute, lower left ventricular ejection fraction, that is, 42 versus 61%, and right ventricular ejection fraction of 44 versus 54%, lower left and right ventricular stroke volumes, that is, 35.5 versus 49.5 millilitres per square metre and 40.9 versus 56.4 millilitres per square metre, respectively, and lower mitral and tricuspid valve inflow e/a wave velocity ratios of 2.02 versus 2.80 and 1.25 versus 2.58, respectively, than the controls. Tricuspid valve annulus velocity, measured by tissue Doppler echocardiography, correlated with right ventricular ejection fraction (r = 0.60, p = 0.05). Right ventricular ejection fraction and indexed right ventricular end-diastolic volume correlated with N-terminal pro-brain natriuretic peptide (r = -0.67, p = 0.03, r = 0.65, p = 0.04, respectively), and right ventricular ejection fraction correlated with the oxygen uptake at the anaerobic threshold (r = 0.67, p = 0.049). Neither left ventricular ejection fraction nor left ventricular volume correlated with N-terminal pro-brain natriuretic peptide or exercise tolerance. The right ventricular function is decreased in the early stages of dilated cardiomyopathy. Right ventricular size and ejection fraction may be important indicators of sub-clinical cardiac failure and we suggest monitoring them routinely in dilated cardiomyopathy.

“…Good correlations, however, have been reported be tween échocardiographie and angiographic measure ments as well as between angiographic and autopsy mea surements of LA volumes [9,21,24], Echocardiography has been found to underestimate cardiac volumes [25]. Nevertheless, the difference be tween angiographic and échocardiographie techniques becomes significant only for large cardiac volumes [25]. The calculations of the LA volumes have been based on the area-length method.…”

Left atrial (LA) emptying is biphasic; however, little information exists about the distribution of active and passive LA emptying. LA volumes and function were studied in 11 normal subjects with echocardiography using the biplane area length method. The LA volumes - maximal, at mitral valve opening; minimal, at mitral valve closure, and at onset of atrial systole (P wave on electrocardiogram) - were 46 ± 12, 29 ± 12, and 18 ± 7 cm^3, respectively. The LA passive emptying volume (maximal minus at P wave) was 17 ± 4 cm3, and the passive emptying fraction (passive emptying volume/maximal volume) was 0.39 ± 0.10. The LA active emptying volume (volume at P wave minus minimal) was 11 ± 5 cm^3, and the active emptying fraction (active emptying volume/volume at P wave) was 0.38 ± 0.07. The LA total emptying volume (maximal minus minimal) was 28 ± 5 cm^3, and the total emptying fraction (total emptying volume/maximal volume) was 0.62 ± 0.07. LA total emptying and active emptying volumes were directly related to LA maximal volume (r = 0.95) and volume at onset of atrial systole (r = 0.92), while LA passive emptying volume was not related to LA maximal volume. The study provides a framework for the evaluation of LA function and will help in understanding not only LA function, but also diastolic left ventricular function in health and disease states.
