Conclusions
Between both operators, our data indicated that 2D-STE analysis showed
excellent agreement for cardiac morphometry parameters (ED and SI), and
good agreement for cardiac function parameters (EndoGLS and FS). Due to
its complexity, the application of fetal 2D-STE remains the domain of
scientific-academic perinatal ultrasound and should be placed preferably
in the hands of skilled operators. At present, from our perspective, an
implementation into clinical practice ‘on-the-fly’ cannot be
recommended.
