“…Although not directly comparable, our data are also consistent with a recent study that demonstrated a reduction in global RV strain and strain rate throughout gestation, followed by a progressive increase in RV strain from birth to the first year of life [51]. This may be attributable to the change in pulmonary vascular resistance during this period.…”

“…Interestingly, the apical segmental longitudinal strain values were similar between these two groups. We have previously demonstrated that only the basal and mid-ventricular segments of the right ventricle free wall increase throughout maturation, while the apical segmental longitudinal strain was unchanged from birth to 1 year of age in healthy term infants[36]. Since the right ventricle is composed on superficial oblique fibers that are arranged in parallel with the AV groove and turn obliquely toward the cardiac apex and continue into the superficial myofibers of the left ventricle[37], the expected physiologic increase of segmental longitudinal strain at the right ventricle side of the apical free wall is likely masked by the contribution of the left ventricle to the contraction patterns of the right ventricle free wall[16].…”

“…Di Salvo et al and Ta-Shma et al utilized automatic functional imaging (AFI) technique, which is a novel non-Doppler methodology based on 2-dimensional acoustic markers tracking, and measures myocardial deformation regardless of angle of interrogation [ 32 , 33 ]. Achieved results were dependent on technique used and not consistent—authors observed stable value of strains [ 30 ], or their increase [ 32 ] or decrease [ 31 ] with gestational age (Table 3 ). In our study, RV free-wall strain and septal strain values were independent of GA. Due to different way of measurement, 2D strain values cannot be directly compared to these measured with 3D tools, however values reported by both techniques are similar (between − 20 and − 25%).…”

“…Functional parameters: Strain parameters in the assessment of fetal RV function were measured mostly with 2D technique to date [30][31][32][33]. Kapusta et al used offline 2D speckle-tracking analysis [31].…”
