Abstract Aims To evaluate standard reporting of cardiac chambers size and function by transthoracic echocardiography (TTE), the EACVI Scientific Initiatives Committee performed a survey across European centres. In particular, the routine use of three-dimensional echocardiography (3DE) and speckle tracking-derived myocardial deformation imaging (STE) was explored. Methods and results A total of 96 European Echocardiography Laboratories from 22 different countries responded to the survey, which consisted of 20 questions. For most of the standard parameters of cardiac chamber size and function, answers from the centres were homogeneous and demonstrated good adherence to current recommendations. In particular, all centres assessed left ventricular (LV) and left atrial (LA) size combining diameter measurements with volumes obtained using the bi-plane Simpson’s method. More variability was observed in the measurements of the right heart chambers and thoracic aorta. Interestingly, >90% of centres had access to 3DE and STE; however, the large majority of centres reserved the use of these techniques for selected cases, particularly for the measure of 3D LV volumes and ejection fraction and global longitudinal strain in patients being considered for cardiac device implantation, surgical intervention (valvular heart disease) or screened for cardiotoxicity. Only 10% of centres used 3DE for right ventricular and LA volumes. Also, <30% of the centres used LA strain imaging. Conclusion In Europe, a good adherence to current recommendations was observed for most of the standard parameters of cardiac chambers quantification by TTE. Advanced echocardiography modalities, such as 3DE and STE, are widely available but used only in selected cases.

Aortico-left ventricular tunnel is a rare congenital cardiac defect, which bypasses the aortic valve via the paravalvar connection from the aorta to the left ventricle. The authors report the history of a 14-year-old boy with aortico-left ventricular tunnel in whom the aortic orifice arose from the right aortic sinus and was closed by a pericardial patch. The diagnosis was confirmed by combined two-dimensional and real time three-dimensional echocardiogram and magnetic resonance imaging. This is the first case, in which these complex diagnostic imaging methods have been used in the pre- and postoperative management of this defect. Optimally the new transthoratic three-dimensional echocardiography would be needed to define the anatomy and functional consequences of the aortico-left ventricular tunnel and in the postoperative follow-up.

Three-dimensional echocardiography is a novel imaging technique based on acquisition and display of volumetric data sets in the beating heart. This permits a comprehensive evaluation of left ventricular (LV) anatomy and function from a single acquisition and expands the diagnostic possibilities of noninvasive cardiology. It provides the possibility of quantitating geometry and function of LV without preestablished assumptions regarding cardiac chamber shape and allows an echocardiographic assessment of the LV that is less operator-dependent and therefore more reproducible. Further developments and improvements for widespread routine applications include higher spatial and temporal resolution to improve image quality, faster acquisition, processing and reconstruction, and fully automated quantitative analysis. At present, three-dimensional echocardiography complements routine 2DE in clinical practice, overcoming some of its limitations and offering additional valuable information that has led to recommending its use for routine assessment of the LV of patients in whom information about LV size and function is critical for their clinical management.

IntroductionThe role of three-dimensional echocardiography (3D-ECHO) chamber quantification in children is still underestimated.Material and methodsIn 43 children 3D-ECHO measurements of end-diastolic (EDV) and end-systolic ventricular volumes (ESV) were compared to cardiac magnetic resonance (CMR) using Bland-Altman analysis and linear regression. The values of left and right ventricular volumes calculated in 3D-ECHO were compared with each other and verified by CMR.ResultsThe values of LV-EDV and LV-ESV measured in 3D-ECHO showed highly significant correlations with CMR (for LV-EDV r = 0.892, p < 0.00001; for LV-ESV r = 0.896, p < 0.00001). In the case of the right ventricle the correlation of 3D-ECHO results with CMR was still high (RV-EDV r = 0.848, p < 0.00001, RV-ESV r = 0.914, p < 0.00001), although mean RV-EDV and RV-ESV in 3D-ECHO were underestimated compared to CMR (by 38% for RV-EDV and 45% for RV-ESV). Correction of 3D-ECHO results using the coefficient of 1.38 and 1.45 for RV-EDV and RV-ESV, respectively, significantly improved the consistency of the results with CMR. 3D-ECHO offered lower mean values of right ventricular volumes compared to the left ventricle. The discrepancy was again reduced by the calculated coefficients.Conclusions3D-ECHO is a valuable tool for assessment of left ventricular volume, which strongly correlates and agrees with CMR. The right ventricular volumes calculated in 3D-ECHO tend to be significantly underestimated in comparison to CMR and corresponding left ventricular volumes obtained from 3D-ECHO. The use of coefficients developed by the study improves the consistency of right ventricular volumes measured by 3D-ECHO with results obtained by CMR and reduces the volumetric discrepancy between ventricles in 3D-ECHO.
