Table 4.

Echocardiographic EDV and ESV using a modified Simpson rule and a single-plane ellipsoid area-length formula applied to the parasternal long-axis view (see text for details). In contrast with the hemisphere-cylinder (HC) model (Tables 1 and 2), significant and marked underestimation of EDV is observed versus full-volume (FV) CMR.

CMR, cardiac magnetic resonance imaging; Echo, echocardiography; EDV, end-diastolic volume; ESV, end-systolic volume; FV, full-volume and SD, standard deviation.

Values are expressed as mean ± SD. Only significant p-values for paired t-tests (vs. CMR-FV) are reported as follows:
