Previous experimental studies demonstrated that three-dimensional echocardiography is an accurate and reproducible method to assess left ventricular mass and dysfunctional mass. In fact, volume-rendered three-dimensional echocardiography may overcome the limitations of two-dimensional echocardiography, because it uses multiple, parallel two-dimensional images to derive quantitative data. To estimate the accuracy of three-dimensional echocardiography, we evaluated 25 patients who had a single myocardial infarction. All patients underwent two-dimensional and transesophageal three-dimensional echocardiography, and contrast (gadolinium) magnetic resonance imaging, considered a reference standard for infarcted tissue detection. The mean extent of dysfunctional mass by magnetic resonance imaging was 28 ± 13 g and by three-dimensional echocardiography was 29 ± 12 g. Linear regression analysis between the two measurements was r = 0.96. Dysfunctional mass derived from three-dimensional echocardiography reflects the real site and extension of damaged myocardium.
