Key result
Doppler pressure gradients showed good agreement with catheter measurements in 3D-printed mitral valves, despite rapid-prototyped valve dimension mean relative errors ranging from 6.2% to 35%.
Why the study?
Does Doppler-derived transmitral pressure gradient accurately reflect catheter-measured gradients in 3D models of mitral valve calcification?
Does Doppler-derived transmitral pressure gradient accurately reflect catheter-measured gradients in 3D models of mitral valve calcification?
In an in vitro model of mitral annular calcification, Doppler-derived pressure gradients showed good agreement with catheter measurements, supporting its clinical use for estimating transmitral gradients.

Agreement in 3D-printed mitral models supports in vitro validation; leaves open clinical translation pending in vivo studies.
Herrmann et al. (2013) studied Mitral annular calcification (n=3). Doppler echocardiography vs. Catheter-measured pressure gradients was evaluated on Transmitral pressure gradient. Doppler pressure gradients showed good agreement with catheter measurements in 3D-printed mitral valves, despite rapid-prototyped valve dimension mean relative errors ranging from 6.2% to 35%.
