lüll Defining Ebstein s malformation using three-dimensional echocardiography Vettukattil JJ; Bharucha T; Anderson RHInteract Cardiovasc Thorac Surg 2007[Dec]; 6 (6): 685-90Ebstein's malformation is difficult to visualise, for both the echocardiographer and the surgeon. The essence of the problem in Ebstein's malformation is the deviation of the hingepoints of the leaflets towards the junctions of the inlet and apical trabecular parts of the right ventricle. Three-dimensional echocardiography offers new insights into the morphology and function of malformed valves, and allows elucidation of all the features. It allows clear visualisation of the valve leaflets, showing the precise morphology of the valve leaflets, the extent of their formation, the level of their attachment, and their degree of coaptation. Visualisation of the mechanism of regurgitation or stenosis is possible, as is more accurate quantification of the regurgitant jet or jets. Subchordal apparatus may be seen more clearly using three-dimensional echocardiography, and their functional anatomy understood. The multiplanar review modality allows examination of the three-dimensional data set even in patients with sub-optimal echocardiographic imaging. Previously, much of this information could only be well-understood at the time of surgery or post mortem, meaning that the majority of the specimens fully examined were at the poorly functioning end of the spectrum. This information is of use in furthering our understanding of this complex lesion as it functions in vivo, and demonstrating which anatomical pathology is significant in producing functional and physiological consequences. It is also of use for the clinician in selecting which patients are amenable to surgical intervention, for either single or biventricular repair, and for the surgeon in planning how to approach the operation. Correlation between three-dimensional echocardiographic findings and surgical findings has already been established, but the effect of this enhanced anatomical knowledge on surgical planning and surgical outcome requires further investigation.|*Echocardiography, Three-Dimensional[MESH]|*Image Interpretation, Computer-Assisted[MESH]|Abnormalities, Multiple/*diagnostic imaging[MESH]|Cardiac Surgical Procedures[MESH]|Ebstein Anomaly/*diagnostic imaging/pathology/physiopathology/surgery[MESH]|Heart Valves/abnormalities/*diagnostic imaging/pathology/physiopathology/surgery[MESH]|Heart Ventricles/diagnostic imaging[MESH]|Humans[MESH]|Myocardium/pathology[MESH]|Patient Selection[MESH]|Severity of Illness Index[MESH]|Ventricular Function[MESH] |
