“…The relation of the anterior leaflet of the mitral valve to the LVOT can be depicted with high precision using RT 3D TOE aiding in the accurate placement of these stent based prosthesis [CoreValve] for the treatment of aortic stenosis. Sadagopan et al showed that 3DE provided accurate measurements of aortic valve annulus and number of valve leaflets, in identifying sites of fusion of the leaflets as well as nodules and excrescences that characterized dysplastic valves [26]. …”

There have been significant advancements in the ability of echocardiography to provide both morphological and functional information in children with congenitally malformed hearts. This progress has come through the development of improved technology such as matrix array probes and software which allows for the off line analysis of images to a high standard. This article focuses on these developments and discusses some newer concepts in advanced echocardiography such is multi-planar reformatting [MPR] and tissue motion annular displacement [TMAD].Our aim is to discuss important aspects related to the quality and reproducibility of data, to review the most recent published data regarding advanced echocardiography in the malformed heart and to guide the reader to appropriate text for overcoming the technical challenges of using these methods. Many of the technical aspects of image acquisition and post processing have been discussed in recent reviews by the authors and we would urge readers to study these texts to gain a greater understanding [1]. The quality of the two dimensional image is paramount in both strain analysis and three dimensional echocardiography. An awareness of how to improve image quality is vital to acquiring accurate and usable data.Three dimensional echocardiography (3DE) is an attempt to visualise the dynamic morphology of the heart. Although published media is the basis for theoretical knowledge of how to practically acquire images, electronic media [eg.] is the only way of visualising the advantages of this technology in real time.It is important to be aware of the limitations of this technology and that much of the data gleaned from using these methods is at a research stage and not yet in regular clinical practice.

“…Other clinical applications include visualisation of sub-aortic pathology and complex left ventricular outflow tract obstructions,9 double chambered ventricles, and variation in septal morphology (figure 4) and its defects 13 . w9 w10 3DE is also used in understanding the morphological details of the aortic valve and accurate measurement of the valve area, aiding in appropriate catheter interventions14 (figure 5). Mitral valve planimetry and quantification of regurgitation using advanced 3D software is now possible as it “provides complementary information as to the mechanisms and sites of AV valve failure in congenital heart disease” 15 .…”

“…Though some progress has been made in 3DE,14 19 age, sex and body weight matched standardised normal values for cardiac chambers and vessels is an important requirement. Similarly, quantification of myocardial deformation in both biventricular and univentricular circulation in pre- and postoperative states is essential to define and understand the progression of pathology.…”

“…RT3DE was also used to define congenitally severe aortic stenosis, and the results from RT3DE were compared with the valve morphology observed during surgery. The sites of fusion of the leaflets were correctly identified by RT3DE in all cases [65].…”
