“…Reference values for RV RV EDA, RV ESA, and FAC have been identified in the neonatal population for both term and preterm infants [73] . As expected, there is an increase in RV areas and FAC Color version available online with gestational age and a linear increase with weight [28] . In the transitional period, RV areas and RV FAC remain relatively stable in healthy term infants.…”

“…Although FAC is affected by loading conditions, it is less sensitive to abnormal geometry and regional abnormalities. RV FAC measurements in term and preterm infants are highly reproducible [28,44,73] .

“…This is an absolute measurement of the distance travelled by the annulus during systole and is not indexed to the length of the right ventricle. It has been validated as an accurate measure of RV function in adult and pediatric patients [69,70] with further research on term and preterm infants demonstrating its acceptable reliability [28,44,68] . The impact of lower gestation and postnatal age reveals a reduction in annular displacement which is consistent with other modalities [30] .…”

“…TDI has been validated in adult [17,20] , paediatric [16,21] , and neonatal populations [22,23] , as well as in foetuses [24] , and has demonstrated acceptable reliability. Normative reference values now exist for preterm and term infants [25][26][27][28] . Lower gestational age preterm infants have lower myocardial velocities in both systole and diastole [26,29,30] .…”

Echocardiography in the neonatal intensive care unit has led to improvements in our ability to assess the neonatal heart in health and disease. Advances in neonatal cardiac imaging have provided the capability to obtain quantitative information that often supersedes the qualitative information provided by conventional methods. Novel quantitative measures of function include the assessment of the velocity of muscle tissue movement during systole and diastole using tissue Doppler velocity imaging, and evaluation of deformation and rotational characteristics of the myocardium utilizing speckle tracking echocardiography or tissue Doppler-derived strain imaging. A comprehensive understanding of these novel functional modalities, their predictive value, and limitations can greatly assist in managing both the normal and maladaptive responses in the newborn period. This article discusses the novel and emerging methods for assessment of left and right heart function in the neonatal population.

Purpose To investigate the possible influence of chest wall conformation on myocardial strain parameters in a consecutive population of infants with pectus excavatum (PE), noninvasively assessed by modified Haller index (MHI). Methods Sixteen consecutive PE infants (MHI >2.5) and 44 infants with normal chest shape (MHI ≤2.5) entered in this prospective case–control study. All infants underwent evaluation by neonatologist, transthoracic echocardiography implemented with two‐dimensional speckle tracking echocardiography (2D‐STE) analysis of both ventricles and MHI assessment (ratio of chest transverse diameter over the distance between sternum and spine), at two time points: within 3 days and at about 40 days of life. Results At 2.1 ± 1 days of life, compared to controls (MHI = 2.01 ± 0.2), PE infants (MHI = 2.76 ± 0.2) were diagnosed with significantly smaller cardiac chambers dimensions. Biventricular contractile function and hemodynamics were similar in both groups of infants. Left ventricular (LV) global longitudinal strain (GLS) (−16.0 ± 2.8 vs. −21.7 ± 2.2%), LV‐global circumferential strain (GCS) (−16.3 ± 2.7 vs. −24.0 ± 5.2%), LV‐global radial strain (GRS) (24.2 ± 3.0 vs. 31.5 ± 6.3%), and right ventricular free wall longitudinal strain (RVFWLS) (−16.0 ± 3.2 vs. −22.3 ± 4.4%) were significantly reduced in PE infants versus controls (all p < 0.001). A strong inverse correlation between MHI and the following parameters: LV‐GLS (r = −0.92), LV‐GCS (r = −0.88), LV‐GRS (r = −0.87), and RVFWLS (r = −0.88), was demonstrated in PE infants, but not in controls, in perinatal period (all p < 0.001). Analogous results were obtained at 36.8 ± 5.2 days after birth. Conclusions Abnormal chest anatomy progressively impairs myocardial strain parameters in PE infants. This impairment might reflect intraventricular dyssynchrony due to compressive phenomena rather than intrinsic myocardial dysfunction.
