Popis: Introduction: Non-contrast 2D TTE (2D NC TTE) is done in patients with HF to assess LV EDV and ESV and EF. 2D contrast and 3D TTE (2D C TTE, 3D TTE) are also done. Hypothesis: There are no distinct cut-offs for LV volumes for 2D C TTE or 3D TTE volumes. And, it is not known which of these measurements should be reported. The relative differences in these measurements, and their relative accuracy, compared to CMR is unknown. Methods: This is an observational, retrospective analysis of 239 HF patients who had 2D NC, 2D C, 3D TTE, and CMR. We measured bi-plane LV EDV and ESV, ml), and EF (%) in the 2D NC and C TTEs, and 3D LV EDV and ESV were measured in one TTE. Results: Data from 35 of the 239 patients are shown. 2D NC LV volumes were significantly smaller than 2D C volumes (EDV: 189±80 Vs. 227±86 and ESV: 133±68 Vs. 158±77, ponly 2D C EDV was significantly smaller than 3D TTE (227±86 Vs. 206±85, p Conclusions: In HF, 2D NC is smaller than 2D C TTE LV volumes, the latter being larger and comparable to CMR. Thus, there is a need to identify specific cut-offs for contrast TTE LV volumes to classify LV size. 3D TTE volumes are comparable to CMR, but smaller than 2D C TTE volumes. Contrast 3D TTE may prove to be most comparable to CMR when this becomes available.
