Does TomTec analysis provide more accurate and reproducible measurements of left ventricular volumes and function compared to QLAB in children with functional single left ventricle?
In children with functional single left ventricle, 3DE using TomTec analysis provides more accurate and reproducible measurements of LV volumes and EF than QLAB, though both underestimate volumes compared to MRI.
Both 3DE modalities tend to underestimate LV volumes, but the correlation of LV volumes and EF between 3DE and MRI still holds well. Despite a longer operating time, TomTec analysis is more accurate and reproducible.
