“…Már szá-mos vizsgálat igazolta az RT3DE szerepét a BK-i térfogatok pontos mérésében kontrasztanyag használata mellett és a nélkül [31], függetlenül a vizsgálatok során alkalmazott szoftvertől [32,33]. Irodalmi adatok alapján az RT3DE az MRI-hez mérhető nagy pontosságot és reprodukálható-ságot mutat a BK-i térfogatok mérése során [32,33].…”

“…Mivel a BK-i modell segítségével a globális és szegmentális BK-i végszisztolés és végdiasztolés térfogatértékek nagy pontossággal meghatározhatók, így globális és az egyes szegmentumokra vonatkoztatott EF is számítható [31,32,33]. Echokardiográfi ás kontrasztanyag alkalmazása mellett az RT3DE pontosabbnak bizonyult a BKfunkció meghatározásában, amelyet az MRI-hez mérhe-tő szorosabb korreláció és egyetértés, valamint az alacsonyabb intra-és interobserver variabilitás jellemzett [31].…”

“…In addition, it is unclear whether the accuracy of 3D-transoesophageal echocardiography is similar in patients with a dilated or aneurysmal left ventricle. Several studies [21][22][23][24][25] have investigated the validation of 3D-transthoracic echocardiography in patients with cardiomyopathy. They show good agreement for measuring stroke volume.…”

The utility of intra-operative three-dimensional transoesophageal echocardiography for dynamic measurement of stroke volume

SummaryMeasurement of left ventricular stroke volume and cardiac output is very important for managing haemodynamically unstable or critically ill patients. The aims of this study were to compare stroke volume measured by three-dimensional transoesophageal echocardiography with stroke volume measured using a pulmonary artery catheter, and to examine the ability of three-dimensional transoesophageal echocardiography to track stroke volume changes induced by haemodynamic interventions. This study included 40 cardiac surgery patients. Haemodynamic variables were measured before and 2 min after haemodynamic interventions, which consisted of phenylephrine 100 lg or ephedrine 5 mg. We used Bland-Altman analysis to assess the agreement between the stroke volume measured by threedimensional transoesophageal echocardiography and by the pulmonary artery catheter. Polar-plot and 4-quadrant plot analyses were used to assess the trending ability of three-dimensional transoesophageal echocardiography compared with the pulmonary artery catheter. Bias and percentage error were À1.2 ml and 20%, respectively. The concordance rate in the 4-quadrant analysis after phenylephrine and ephedrine administration was 75% and 84%, respectively. In the polar-plot analysis, the angular concordance rate was 66% and 73% after phenylephrine and ephedrine administration, respectively. Three-dimensional transoesophageal echocardiography was clinically acceptable for measuring stroke volume; however, it was not sufficiently reliable for tracking stroke volume changes after haemodynamic interventions.

“…Moreover, there is a second theoretical approach, based on bilinear, rather than linear, approximation of the time-varying elastance curve, to calculate E es (24). This latter approach has not been tested in the clinical setting.It is well established that real-time three-dimensional (3D) echocardiography (RT3DE) allows more accurate quantification of LV volumes than 2D echocardiography (7,9,14,25). In addition, it has been shown that end-systolic LV pressure can be accurately estimated noninvasively by tonometry from the carotid artery (5).…”

Gayat E, Mor-Avi V, Weinert L, Yodwut C, Lang RM. Noninvasive quantification of left ventricular elastance and ventricular-arterial coupling using three-dimensional echocardiography and arterial tonometry. Am J Physiol Heart Circ Physiol 301: H1916-H1923, 2011. First published September 9, 2011; doi:10.1152/ajpheart.00760.2011.-Most techniques previously used to assess left ventricular (LV) end-systolic elastance (E es) and ventricular-arterial coupling (CLV-A) relied on invasive measurements and data acquisition over a wide range of loading conditions. Our goals were to 1) assess the feasibility of noninvasive assessment of E es and CLV-A using real-time three-dimensional echocardiography (RT3DE) and arterial tonometry; 2) test the ability of this approach to detect changes in LV contractility; and 3) study its reproducibility. We studied pharmacologically induced changes in inotropic state (5 and 10 g·kg Ϫ1 ·min Ϫ1 dobutamine) in normal volunteers (N ϭ 8) and compared 10 normal volunteers with 10 patients with dilated cardiomyopathy (DCM; ejection fraction Ͻ 35%). RT3DE LV images, calibrated carotid artery tonometry, and Doppler tracings were obtained to noninvasively estimate Ees and CLV-A, using two alternative calculations. Dobutamine caused a significant stepwise increase in blood pressure, heart rate, ejection fraction, and Ees and a decreased CLV-A. In patients with DCM, Ees was significantly reduced and CLV-A elevated, compared with controls. Both inter-and intraobserver variability were good for all measured parameters, as reflected by intraclass correlation coefficients (Ͼ0.8) and coefficients of variation (Ͻ20%). While both Ees estimates showed significant differences between DCM patients and controls, one estimate resulted in no overlap and better reproducibility (interobserver intraclass correlation coefficient: 0.83 vs. 0.47, coefficients of variation: 20 vs. 29%). This is the first study to test the feasibility of using RT3DE-derived LV volumes in conjunction with arterial tonometry to noninvasively quantify LV elastance and CLV-A. This approach was found to be sensitive enough to detect expected differences in LV contractility and reproducible. Due to its noninvasive nature, this methodology may have clinical implications in various disease states. left ventricular contractility LEFT VENTRICULAR (LV) pressure-volume loops provide valuable information on LV systolic and diastolic function, as well as on LV-arterial coupling (C LV-A ) (8). End-systolic elastance (E es ), the slope of the end-systolic pressure (ESP)-volume relationship, has been used as a load-independent index of myocardial contractility (2). In the past, to obtain pressure-volume loops, invasive pressure and volume measurements were required to be obtained under a wide range of loading conditions, thus limiting the clinical applicability of this technique. To avoid these limitations, several investigators have proposed invasive solutions to estimate E es from a single cardiac cycle (23,24,27), and, more recently, the accuracy of ...
