Resumen:
Objective: M-mode and 2D have been proposed for evaluating fetal
myocardial thickness. However, studies comparing the performance of both
modalities are lacking. We aimed to compare 2D versus M-mode
reproducibility for assessing myocardial wall thicknesses. Methods: A
prospective study including 45 healthy fetuses from low-risk pregnancies
evaluated between 18 and 41 weeks of gestation. Left and right
ventricular free-wall and septal myocardial thicknesses were measured at
end-diastole (ED) and end-systole (ES) in transverse 4-chamber view
using 2D and M-mode. Intra- and interobserver reproducibility was
evaluated by the concordance correlation coefficient (CCC). Both
techniques were compared by t-test of the CCC. Results: 2D and M-mode
demonstrated excellent and similar intraobserver repeatability, with the
best concordance in ES septal thickness (M-mode CCC 0.956 versus 2D-mode
CCC 0.914). Interobserver reproducibility demonstrated also a high
concordance, optimal in ES left ventricular free wall (M-mode 0.925
versus 2 D 0.855). Comparison of both techniques demonstrated a high
concordance in all measurements, except for ED septal thickness with
better reproducibility using M-mode (CCC 0.954 versus 0.847, p = .017).
Conclusions: 2D and M-mode can be used in a reproducible manner for
measuring fetal myocardial thickness, with a slightly better performance
of M-mode for assessing ED septal wall thickness.
