Comparison of wall thickness between 2D clinical and 3D model measurements.

Variable Control (n = 19) HCM (n = 19) P-value
2D CLINICAL MEASUREMENTS
IVSd, mm 8.4 ± 1.4 17.0 ± 6.1 <0.001
IVSs, mm 12.2 ± 2.3 21.4 ± 5.4 <0.001
LVPWd, mm 6.1 ± 1.4 8.8 ± 3.4 0.009
LVPWs, mm 12.7 ± 2.3 18.5 ± 5.4 <0.001
FS, % 35.0 ± 6.1 44.2 ± 7.9 <0.001
3D MODEL MEASUREMENTS
WTED,max, mm 8.1 ± 1.4 16.5 ± 5.2 0.001
WTES,max, mm 12.4 ± 1.5 22.1 ± 5.0 <0.001

Data are expressed as mean ± SD. HCM, hypertrophic cardiomyopathy; IVSd (IVSs), interventricular septum in diastole (systole); LVPWd (LVPWs), left ventricular posterior wall in diastole (systole); FS, fractional shortening. WTED,max (WTES,max), maximal wall thickness among 16 regional segments in diastole (systole) from 3D model. Bold values mean statistically significant.
