WebConclusions: Quantitative assessment of functional MR severity by 3D TEE may be superior to 2D methods by permitting more direct measures of PISA. Two-dimensional TEE techniques for assessing functional MR severity that rely on an HS- or HE-PISA shape may underestimate the EROA due to geometric assumptions that do not account for asymmetry. WebJan 22, 2024 · Small errors in PISA radius measurement lead to potentially large changes in the quantitative assessment of MR severity. Noncircular and multiple orifices complicate the PISA-based quantitation of MR.
