“…7D). Recent studies have confirmed that 3DE measurements of the RVEF are accurate, reproducible, and correlate well with CMR both in adults and children [20,21,27,28]. In the most recent meta-analysis aimed at exploring the accuracy of different imaging modalities (2DE, 3DE, radionuclide ventriculography, computed tomography [CT], gated single-photon emission CT, and invasive cardiac cineventriculography) for RVEF using CMR as a reference method, 3DE has proven to be the most reliable technique, overestimating the RVEF by only 1.16% with the lowest limits of agreement (form -0.59 to 2.92%) [29].…”

“…7). 3DE measurements are closely correlated (but slightly underestimate) with RV volumes measured by CMR both in children and adults [18][19][20][21], and by volumetric thermodilution during cardiac catheterisation [22]. Normative data for 3DE RV volumes and ejection fraction (EF) including age-, body size-, and sex-specific reference values based on large cohort studies of healthy volunteers have recently become available (Table 2) [23,24].…”

A háromdimenziós echokardiográfia a veleszületett szívhibák egy új diagnosztikus vizsgálómódszere, amelynek szerepe egyre növekszik a szívműtétek tervezésében, a katéter-intervenciók vezérlésében és a szív funkcionális vizsgálatában. Célunk áttekintést adni a veleszületett szívhibák diagnosztikájában alkalmazható háromdimenziós echokardiográfiás módszerekről és azok diagnosztikus jelentőségéről. A legújabb csúcstechnikát a valós idejű (real time) transthoracalis háromdimenziós módszerek jelentik, amellyel szerzett első tapasztalatainkról is beszámolunk. Betegek,módszer: 1 év alatt 32 vizsgálat történt, 26 esetben gyermek-és fiatalkorban, 6 esetben magzatban. Életkor: 0,6-28 év átl.: 9,8 év. A vizsgálatokat Philips Epiq G7 gépen, matrix X5-1 transzducerrel végeztük, 6 esetben off line analízis is történt (Q-Lab 10,3). Eredmény: A kétdimenziós echokardiográfia után végzett real-time echokardiográfia 6 betegnél (20%) szolgált fontos, kiegészítő információval. Az aortagyök betegségeiben és az atrioventricularis billentyűk malformációiban kiemelkedő szerepe volt a preoperatív döntéshozatalban, mind a morfológia mind a multiplex regurgitációs jetek megítélésében. Következtetések: A veleszületett szívbetegségek kivizsgálása során a konvencionális kétdimenziós echokardiográfia mellett mindennapi gyakorlatunkban helye van a real time háromdimenziós echokardiográfiának, elsődlegesen a kongenitális aortagyök és atrioventricularis billentyűk betegségeiben. FeasibilityandEffectivenessof3-dimensionalEchocardiographyincongenitalheartdiseasesThree-dimensional echocardiography (3DE) is a new diagnostic tool and has increasing role in the management of patients with congenital heart disease (CHD), particularly with pre-surgical planning, guidance of catheter intervention, and functional assessment of the heart. 3DE is increasingly used in children because of good acoustic windows and the non-invasive nature of the technique. Our aim is to provide a review of the optimal application of 3DE in CHD and to assess the benefit of utilizing real time transthoracic echocardiograpy (RRT-3DE) performed within one year in our Clinic for diagnosing and as a guide for appropriate treatment of different types of congenital heart disease. Methods: 32 patients aged 0.6-28, mean 9.8 years, including 6 fetus were evaluated by both 2D-TTE and RTT-3DE. The 3D real time reconstruction was done with Epiq G7 Equipment (Matrix Probe5-1) using Q Lab 10.3 software. In six pts offline analyses were also performed. Results: RTT-3DE added additional data compared with 2DE in 6 (20%) of pts. RTT-3DE had a particular value in demonstrating the morphology of aortic root and atrioventricular valves anatomy and the demonstration of the origin and the direction of multiple regurgitation jets, which had clinical value in preoperative decision making. Conclusion: On the basis of our experience RRT-3DE is superior to the traditional 2DE in congenital heart diseases providing incremental value in the assessment of aortic root diseases and atrioventricular congenital v...

“…Real-time 3D techniques have been shown to accurately provide objective measurement of RV volumes 19 and are especially attractive after cardiac surgery, when conventional indices of longitudinal RV function are generally reduced. 20 Strain, particularly speckle tracking technique of the free wall, is a promising technique.…”

Heart failure (HF) is an epidemic with an increasing prevalence and an absolute mortality rate of approximately 50 % within 5 years of diagnosis. Imaging plays a main role in HF diagnosis, assessment of aetiology and treatment guidance. This article reviews current HF applications for all the available non-invasive imaging modalities: echocardiography, cardiovascular magnetic resonance (CMR), nuclear imaging-positron emission tomography (PET) and single-photon emission computed tomography (SPECT) and computed tomography (CT). Echocardiography, with its recent developments, such as 3D echo, is the main imaging test used in the evaluation of HF patients, given its availability and reliability in assessing cardiac structure and function. CMR allows the characterisation of myocardial tissue, in addition to providing information on the structure and cardiac function, so it is a great help in the determination of HF aetiology and may predict patient outcomes. Nuclear imaging can detect ischaemia and viability and can obtain additional prognostic data. Cardiac CT is EchocardiographyAlthough echocardiography is a relatively 'ancient' technique, its versatility makes it unique in the provision of volumes, function, haemodynamics or valvular regurgitation. In addition, because of its availability, safety and low cost, echocardiography is the first and most widely used test for the diagnosis, selection of appropriate treatment and prognosis of HF.1 Echocardiography is also the most used imaging method in the reassessment of HF patients. It remains unclear when to repeat echocardiographic exams, but it is deemed appropriate at least in patients with worsening symptoms. Systolic FunctionGlobal left ventricular (LV) function is of paramount importance regarding therapeutic decisions. Visual estimation of ejection fraction (EF), the Teichholz and Simpson methods, have been widely validated. 2,3However, in 2D imaging, because of its operator-dependent nature, repeated testing has a high probability of producing variable volume and EF results.The apparition of 3D fully sampled matrix transthoracic echocardiography has enabled easier acquisition of images, 4 simplifying its routinary application. There have been many studies comparing 2D and 3D echocardiography (2DE and 3DE) and a 'reference' standard (generally CMR). A recent meta-analysis of all 3DE studies evaluating LV volumes and EF demonstrated that 3DE generally underestimated volumes, but not as significantly as 2DE. There was also less variability than 2D compared with CMR.5 Nonetheless, 3DE echocardiography may be challenging and not practical in patients with low image quality (e.g. critical patients), in whom 2DE measures are more realiable. 3DE is also a less standardised techique than 2DE, and because of this reason most laboratories use the more universally applicable 2DE measurements in clinical practice. Only recently, large analyses of LV parameters using 3DE in large cohorts of healthy individuals have been published to establish race, age and gender-specific ...
