“…We have previously published our findings evaluating global, circumferential, and longitudinal assessments of the RV and LV using speckle‐tracking software, which are important diagnostic tools used in evaluations of the heart in neonatal and pediatric patients . One could pose the question as to why it would be necessary to measure the EDV and ESV and compute the SV, SV/kg, CO/kg, and EF.…”

“…Two hundred healthy fetuses with accurate first‐ and/or second‐trimester dating ultrasound (US) scans were examined between 20 and 40 weeks’ gestation. The 200 fetuses were part of a cross‐sectional analysis of a prospective study used in previous studies from our group . According to criteria described by Altman and Chitty to construct reference ranges for fetal biometric measurements, the following principles were followed: (1) fetuses were examined once during the study; (2) the fetuses were not at risk for congenital heart abnormalities, growth restriction, or other fetal anomalies; (3) fetuses did not have US‐detected malformations, macrosomia, or intrauterine growth restriction (IUGR) at the time of the examination; and (4) the mothers of the fetuses did not have clinical conditions (diabetes mellitus, chronic hypertension, and preeclampsia) that could affect fetal growth.…”

“…Differences in left ventricular (LV) and right ventricular (RV) size and function have been reported in various fetal disease states . In prior studies, we have reported using speckle‐tracking software to evaluate various parameters of the fetal LV and RV, including the area, 24‐segment transverse widths, 24‐segment transverse fractional shortening, fractional area change, as well as longitudinal basal‐apical contractility and displacement . These measurements reported from our group have not yet been applied postnatally.…”

Objectives This study was conducted to evaluate left ventricular (LV) size and function in healthy fetuses and to test a cohort of fetuses at risk for abnormal function using speckle‐tracking software. Methods Two hundred control fetuses were examined between 20 and 40 weeks’ gestation. With the use of offline speckle‐tracking software, the end‐diastolic and end‐systolic volumes were measured and the following computed: stroke volume (SV), SV per kilogram, cardiac output (CO), CO per kilogram, and ejection fraction. These were regressed against 7 independent variables related to the size, weight, and age of the fetuses. Five fetuses with risk factors for LV dysfunction were examined to sample the validity of the data from the control group. Results The R2 values for measurements of the end‐diastolic volume, SV, and CO correlated with the 7 independent variables of fetal size and age (0.7–0.78), whereas the SV/kg, CO/kg, and ejection fraction had lower R2 values (0.02–0.1). The measurements were normally distributed (Shapiro‐Wilke > 0.5). The 5 fetuses at risk for abnormal LV function had measurements of LV size and function that were consistent with the expected pathologic condition. Conclusions Speckle tracking can provide a comprehensive evaluation of the size and function of the fetal LV.

“…The sizes of the two ventricles are similar in normal fetuses . Ventricular disproportion with a larger ratio of the right ventricle to the left ventricle (RV/LV) is a common cause of referral for extended fetal echocardiography after targeted organ scan by obstetric sonographers.…”

Objectives Isolated prenatal ventricular disproportion with a dominant right ventricle represents a challenge in decision‐making for both physicians and pregnant women. In the current study, we sought to delineate the postnatal outcomes of these cases. Methods This retrospective analysis included consecutive cases of isolated ventricular disproportion identified using complete fetal echocardiography at the Fetal Heart Center of Xinhua Hospital from January 2014 to October 2017. Postnatal cardiac outcome was examined using transthoracic echocardiography within the first 6 months after birth. Results A total of 90 fetuses were included in the final analysis. The median gestational age (GA) at diagnosis was 29 weeks (range 24 to 36). At postnatal examination, cardiac malformations were detected in 39 cases (43.3%), including 25 (27.8%) cases of congenital cardiac septal defects, eight (8.9%) of persistent left superior vena cava, four (4.4%) of left‐sided obstructive diseases, and one (1.1%) case of coronary fistula. Nineteen cases (21.1%) with fetal cardiac malformations had significant lower GA at diagnosis (P = .01) and greater right to left ventricle ratio (1.38 vs 1.30, P = .02). Neonatal surgical intervention was not required in any of the cases. Conclusions Isolated prenatal ventricular disproportion with a dominant right ventricle comprises minor postnatal cardiac malformations and doesn't require neonatal intervention.

“…Lastly, we have reported a number of cardiac measurements derived from speckle‐tracking analysis of the right and left ventricular endocardium that analyze ventricular size, shape and contractility. This analysis, a relatively new adaptation of speckle‐tracking assessment, enables the examiner to obtain numerous cardiac measurements from a single endocardial tracing of each ventricle, which takes less than 3 min, and is now commercially available on ultrasound platforms dedicated primarily to fetal evaluation.…”
