Key result
Three-dimensional TEE assessment of functional mitral regurgitation yielded significantly larger PISA (4.65 vs 2.10 cm2) and EROA (0.44 vs 0.19 cm2) compared to 2D hemispheric assumptions (P<0.0001).

3D TEE may refine functional MR severity grading; leaves open effects on decisions and outcomes.

Does 3D TEE provide more accurate assessment of PISA and EROA compared to 2D TEE in patients with functional mitral regurgitation?
Absolute Event Rate: 4.65% vs 2.1%
p-value: p=< 0.0001
3D TEE provides a more accurate assessment of functional mitral regurgitation severity than 2D TEE by avoiding geometric assumptions that underestimate the effective regurgitant orifice area.
Ashikhmina et al. (2014) conducted an observational in functional mitral regurgitation (n=24). 3-dimensional transesophageal echocardiography (3D TEE) vs. 2-dimensional transesophageal echocardiography (2D TEE) was evaluated on Proximal isovelocity surface area (PISA) (p=< 0.0001). Three-dimensional TEE assessment of functional mitral regurgitation yielded significantly larger PISA (4.65 vs 2.10 cm2) and EROA (0.44 vs 0.19 cm2) compared to 2D hemispheric assumptions (P<0.0001).
