Dimensional Echocardiography

AbstractBackgroundThree-dimensional echocardiography is a non-invasive imaging technique. The fact that it permits volumetric analyses independently of geometrical assumptions makes it a putatively useful method for the precise measurement of the volumes of the irregularly shaped right ventricles in children. The aim of this study was to assess the feasibility of this method and its agreement with angiocardiography based estimates of right ventricular volume in children with congenital heart disease.MethodsWe studied 102 children with congenital heart disease. The angiocardiographic right ventricular volumetry was performed using a biplanar technique using Simpson's rule and corrected with Lange's correction factors. The echo data sets were registered trans-thoracically with a rotating transmitter. Volumes were calculated after manual planimetry by adding the volumes of the individual slices.ResultsCalculation of right ventricular volume echocardiographically was possible only in 34% of patients, mostly infants and toddlers. In comparison to angiocardiography, the measured volumes were 1.1 ±6.9 ml (19.5 ±34.1%) or 6.3±9.4ml (42.5±33.6%) smaller during systole or diastole, respectively. The limits of agreement were −12.5 and 13.6ml, or 12.45 and 25.15ml during systole or diastole, respectively. When plotted to a logarithmical scale, the correlation coefficients r2 were 0.70 for systolic and 0.79 for diastolic measurements.ConclusionTransthoracic 3-dimensional echocardiography with a rotating transmitter is feasible for volumetry only in small children. The volumes measured were significantly smaller than the ones calculated from the angiocardiographic images. The correlation between the two methods is moderate.

Objective: The purpose of this study was to determine whether Real-time three-dimensional echocardiography (RT3D) is superior to two-dimensional echocardiography (2D) in determining mechanisms and site(s) of atrioventricular valve (AV valve) regurgitation in congenital heart disease. Background: Data is lacking on the utility of RT3D echo in congenital abnormalities of the AV valves. Methods: Between May 2006 and April 2007, 35 cases were prospectively studied prior to AV valve repair (20 left and 15 right) by 2D transthoracic (2DTTE), 2D transesophageal (2DTEE) and RT3D (Philips matrix array X 3–1 and X 7–2). Thirty one had significant and 4 mild regurgitation. Ages ranged from 24 days to 30 years (mean 13.8 years), weight 2.2 to 42kg (mean 26.1Kg). The 2DTTE and TEE were reviewed by a blinded observer. The 3D data were analyzed by a separate observer. In 28 patients surgical findings and regurgitation from saline testing were recorded by digital video and later analyzed by an experienced cardiac surgeon. The remaining 7 had a detailed description of the valve morphology documented immediately after surgery. Surgical findings were used as the gold standard for the assessment of structural abnormalities, with RT3D for the evaluation of regurgitation. Results: See table for structural abnormalities. For both the left and right AV valve, saline testing provided a poorer correlation with RT3D color Doppler jet location, in particular for regurgitant jets from the commmissures (p < 0.01). Conclusion: Transthoracic RT3D provides new and superior information as to the mechanisms and site(s) of AV valve failure in congenital heart disease.

Dimensional Echocardiography

Echocardiography plays a key role in the diagnosis and management of adult patients with congenital heart disease and is considered the first-line diagnostic technique. Apart from traditional cross-sectional imaging, three-dimensional echocardiography and strain and strain rate imaging were introduced for specific indications and for better describing anatomical details and functional consequences of the different congenital lesions. For specific indications, additional imaging may be required including cardiac magnetic resonance imaging and computational tomography. Especially in adult congenital heart disease, echocardiographic imaging may be limited by poor acoustic windows and additional evaluation using other imaging modalities may be required. Additionally, MRI and CT imaging have proven to be extremely valuable for evaluation of right ventricular size and function and for describing extracardiac anatomy (pulmonary arteries, pulmonary veins, and aorta).

Presented in this work is a detailed methodology of how to properly print 3-dimensional (3D) heart models starting from computed tomography (CT) scan and using the Mimics Innovation Suite (Mimics and 3-matic) software package (from Materialize, Leuven, Belgium). The methodology starts by segmenting the clinical DICOM files to retain masks of gray value range of interest. Specifically, retained is the blood volume contained in the heart. Using Mimics, this is accomplished by creating mask and then editing and refining the relevant mask in order to isolate the blood within a certain range of Hounsfield Units (HU). A second mask is created using different gray value ranges to isolate the tissues of the heart. Both 3D models are transferred to 3-matic where integrated Boolean operations are executed to subtract the geometric entities thus retaining the 3D geometry of the heart (including myocardium, cavities, and arteries) of interest. The retained model geometry consists of the muscle surface of the heart and enclosing the hollowed cavities inside that represent the blood volume. Following further processing in 3-matic, the 3D model is now ready for 3D printing. At the American University of Beirut (AUB), a ProJet 3510 SD (3D Systems) is employed to print the heart models (both sectioned and whole). Printed 3D models are employed within the Program for Congenital Heart Disease at AUB that represents a model for clinical applications, education, and research as the first such initiative in Lebanon and the Middle East region.
