“…Early-generation 3DE machines created data sets by reconstructing 2-dimensional images 9 using a variety of spatial locators. 10 Right ventricular mass and volumes using such 3D technologies are reported in patients with congenital heart disease, 11,12 with good correlation and agreement with CMR. Altmann et al 2 demonstrated that 3DE provided estimates of ventricular volumes, EF, and mass in pediatric patients with single ventricles that were comparable to CMR estimates.…”

Background-Quantitative assessment of ventricular volumes and mass in pediatric patients with single-ventricle physiology would aid clinical management, but it is difficult to obtain with 2-dimensional echocardiography. The purpose of the present study was to compare matrix-array 3-dimensional echocardiography (3DE) measurements of single-ventricle volumes, mass, and ejection fraction with those measured by cardiac magnetic resonance (CMR) in young patients. Methods and Results-Twenty-nine patients (median age, 7 months) with a functional single ventricle undergoing CMR under general anesthesia were prospectively enrolled. The 3DE images were acquired at the conclusion of the CMR. Twenty-seven of 29 3DE data sets (93%) were optimal for 3DE assessment. Two blinded and independent observers performed 3DE measurements of volume, mass, and ejection fraction. The 3DE end-diastolic volume correlated well (rϭ0.96) but was smaller than CMR by 9% (PϽ0.01), and 3DE ejection fraction was smaller than CMR by 11% (PϽ0.01). There was no significant difference in measurements of end-systolic volume and mass. The 3DE interobserver differences for mass and volumes were not significant except for ejection fraction (8% difference; PϽ0.05). Intraobserver differences were not significant. Conclusions-In young pediatric patients with a functional single ventricle, matrix-array 3DE measurements of mass and volumes compare well with those obtained by CMR. 3DE will provide an important modality for the serial analysis of ventricular size and performance in young patients with functional single ventricles.

“…The dynamic RV reconstruction scheme was shown to be accurate by using the prism method. In common with other volumetric methods (13,15,17) based on geometric reconstruction of images, the prism method places no geometric assumption on the chamber whose volume is to be measured. It can be used with other noninvasive digital imaging modalities, including magnetic resonance and computed tomography scanning, in addition to 3-D echocardiography.…”

We describe a novel functional imaging approach for quantitative analysis of right ventricular (RV) blood flow patterns in specific experimental animals (or humans) using real-time, three-dimensional (3-D) echocardiography (RT3D). The method is independent of the digital imaging modality used. It comprises three parts. First, a semiautomated segmentation aided by intraluminal contrast medium locates the RV endocardial surface. Second, a geometric scheme for dynamic RV chamber reconstruction applies a time interpolation procedure to the RT3D data to quantify wall geometry and motion at 400 Hz. A volumetric prism method validated the dynamic geometric reconstruction against simultaneous sonomicrometric canine measurements. Finally, the RV endocardial border motion information is used for mesh generation on a computational fluid dynamics solver to simulate development of the early RV diastolic inflow field. Boundary conditions (tessellated endocardial surface nodal velocities) for the solver are directly derived from the endocardial geometry and motion information. The new functional imaging approach may yield important kinematic information on the distribution of instantaneous velocities in the RV diastolic flow field of specific normal or diseased hearts. cardiac image analysis; ventricular function; cardiac fluid dynamics; right ventricle; heart chamber volume QUANTITATIVE ANALYSIS of three-dimensional (3-D) digital cardiac images has become increasingly important given the recent advances in the digital cardiac imaging techniques of 3-D echocardiography, magnetic resonance imaging, computed tomography, and digital fluoroscopy (1,24,26). The growth of these digital imaging techniques is accompanied by an increasing usage of image manipulation tools, providing more elaborate image analysis and measurement and quantitative evaluation and leading to more refined diagnostic accuracy than visual interpretation alone. Moreover, complex mathematical procedures are being used to localize and highlight important changes in cardiac function that cannot be visually detected directly from the original images. With the concurrent development of high-performance computers and analytical software, a functional sort of imaging can now evolve, geared toward the creation of physiological images that are the result of a mathematical simulation derived from a set of images. Such functional imaging will allow visualization and understanding of the evolution of any dynamic process of interest (filling, ejection) within the heart. Accordingly, it should allow better insights into cardiac physiology and pathophysiology and may possibly detect warning signs of diseases not yet overt.This study developed innovative dynamic geometric chamber reconstruction models for use in functional imaging analyses of right ventricular (RV) filling dynamics and physiology. With the use of a new volumetric "prism method," it is first shown that the geometric chamber reconstructions provide accurate and reliable dynamic instantaneous RV chamber geometry ...

“…Compared to CMR, echocardiography is relatively inexpensive and could be a good method for the serial assessment of the RV function, not least in patients with contraindications to CMR, namely the growing number of patients with cardiac pacemakers or implantable defibrillators. It is deserving of note that echocardiography is deemed an inaccurate tool for the quantitative assessment of the RV function because of a lack of an ideal geometric model for the evaluation of ventricular volumes (22,23).The major potential advantages of strain and SR imaging for the assessment of the RV function are the independence of geometric assumptions and endocardial border tracing. In addition, both strain and SR images are feasible in the majority of patients (even in the presence of low-quality 2-D imaging), reproducible, and relatively load and rate independent (24)(25)(26).…”

Original Investigation Özgün Araşt›rma 536ÖZET Amaç: Fallot tetralojisi (TOF) siyanotik konjenital kalp hastalığının en sık görülen şeklidir. Günümüzde, TOF onarımı sonrası rezidüel pulmoner yetersizliği (PR) olan hastaların sayılarında artış ile karşı karşıyayız. Sağ ventrikül (RV) hacim ve fonksiyonu klinik karar vermeyi etkileyen en önemli faktörler arasındadır. Kardiyak manyetik rezonans (CMR) RV fonksiyonunun nicel değerlendirilmesi için altın standart yöntemdir; ancak, rutin klinik takip için pahalıdır ve bazen kontrendikedir. Biz TOF onarımı yapılan hastalarda CMR ile RV sistolik fonksiyonu değerlendirmesini Doppler kaynaklı strain (S) ve strain rate (SR) görüntülemesi ile karşılaştırmaya çalıştık. Yöntemler: Kesitsel bir çalışmada, TOF onarımından epey sonra şiddetli PR'li 70 hasta (22 kadın, ortalama yaş=22±4,9) değerlendirildi. RV serbest duvarının bazal, mid ve apikal segmentlerinde peak sistolik strain ve SR ölçülerek kısa-aks sine MR da ölçülen RV fonksiyonu ile karşılaştırıldı. RVEF ve S/SR arasındaki ilişkiler sıra lojistik regresyon modelleri ile incelendi.
