Distalless expression in crustaceans and the patterning of branched limbs

The ability of two-dimensional echocardiography to detect and to evaluate the extent of wall motion abnormalities is limited by the use of few selected, nonparallel, views of the whole left ventricle. This leads to an incomplete appreciation of the spatial relationships between various cardiac structures and inaccuracy in quantitative data as a result of using of geometric assumptions. Dynamic volume-rendered three-dimensional echocardiography has the ability to overcome the above limitations. In this article we review the use of volume-rendered three-dimensional echocardiography in the diagnosis and assessment of ischemic heart disease, including complications related to myocardial infarction.
