Observer variability
Intraobserver ICC for the ASD parameters as the maximal diameter, the
minimal diameter and circular index via 2D-TEE were 0.96,0.93,0.94,
respectively. Intraobserver ICC for the maximal diameter, the minimal
diameter, circular index and circumference values based on 3D-TEE images
were 0.98, 0.92, 0.98 and 0.93, respectively. The Intraobserver ICC for
the corresponding parameters measured from 3D printed models were 0.97,
0.92, 0.99 and 091, respectively. Interobserver ICC for the same
parameters based on 2D-TEE were 0.93,0.90,0.98, respectively, and via
3D-TEE were 0.98, 0.94, 0.98,0.90, respectively. Interobserver ICC of
the maximal diameter, the minimal diameter, circular index and
circumference based on 3D printed model were 0.95,0.90,0.98 and 089,
respectively.
