Cardiac function analysis is the main focus of echocardiography. Left ventricular ejection fraction (LVEF) has been the clinical standard, however, LVEF is not enough to investigate myocardial function. For the last decade, speckle tracking echocardiography (STE) has been the novel clinical tool for regional and global myocardial function analysis. However, 2-dimensional imaging methods have limitations in assessing 3-dimensional (3D) cardiac motion. In contrast, 3D echocardiography also has been widely used, in particular, to measure LV volume measurements and assess valvular diseases. Joining the technology bandwagon, 3D-STE was introduced in 2008. Experimental studies and clinical investigations revealed the reliability and feasibility of 3D-STE-derived data. In addition, 3D-STE provides a novel deformation parameter, area change ratio, which have the potential for more accurate assessment of overall and regional myocardial function. In this review, we introduced the features of the methodology, validation, and clinical application of 3D-STE based on our experiences for 7 years.

Intraoperative three-dimensional (3D) transesophageal echocardiography (TEE) facilitates an understanding of the complex cardiac pathology that is not fully delineated in a two-dimensional (2D) echocardiographic evaluation, and it suggests earlier and more precise surgical planning and intraoperative decision making. In the present case, the intraoperative 2D-TEE midesophageal long-axis view indicated a significant narrowing of the left ventricular outflow tract (LVOT) area by a band-like structure that vertically traversed the middle of the LVOT and connected to the anterior mitral leaflet base and the interventricular septum. However, additional 3D-TEE images of the LVOT and their cropped and rendered 2D images showed that web-like tissue, which presumably had grown around the patch closure from a previous atrioventricular septal defect, was obstructing the LVOT partially.

BACKGROUND: Three-dimensional echocardiography has good feasibility and real image display in dynamic and spatial cardiac structures. So we designed this study to assess both the feasibility and potential role of three-dimensional echocardiography for the evaluation of cardiac structures and adjacent relationships. METHOD: We studied 25 patients with various heart structures. Cross-sectional images of specific interesting region were acquired from multiplane transesophageal echocardiography and reconstructed to three-dimensional images by TomTec image processing system. These images were presented in volume-rendered dynamic display for assessing of additonal informations. RESULTS: Three-dimensional reconstructions of usual viewpoints and interesting cut planes were possible in all patients. When compared with standard two dimensional images, additional informations were provided in all reconstructed cases. Among these images, mitral valve morphology, aortoseptal continuity and interatrial septum were the structures for which three-dimensional echocardiography were most useful. CONCLUSION: Although it was preliminary datas which needs large-scale randonmized prospective studies, three-dimensional echocardiograpy may be most potent and promising methods in evaluating anatomic and functional assessment of heart structures.
