“…This finding indicates the additive value of considering strain parameters of both, LV and RV, in the evaluation of fetal cardiac function. Using echocardiography, recent studies suggested that myocardial strain reflects the changing physiology in fetuses with CHD [ 23 – 25 ], e.g., altered strain parameters were observed in fetuses with tetralogy of Fallot [ 26 ]. In fetuses with transposition of the great arteries, echocardiographic strain measures predicted urgent postnatal intervention [ 27 ].…”

Objectives Assessment of myocardial strain by feature tracking magnetic resonance imaging (FT-MRI) in human fetuses with and without congenital heart disease (CHD) using cardiac Doppler ultrasound (DUS) gating. Methods A total of 43 human fetuses (gestational age 28–41 weeks) underwent dynamic cardiac MRI at 3 T. Cine balanced steady-state free-precession imaging was performed using fetal cardiac DUS gating. FT-MRI was analyzed using dedicated post-processing software. Endo- and epicardial contours were manually delineated from fetal cardiac 4-chamber views, followed by automated propagation to calculate global longitudinal strain (GLS) of the left (LV) and right ventricle (RV), LV radial strain, and LV strain rate. Results Strain assessment was successful in 38/43 fetuses (88%); 23 of them had postnatally confirmed diagnosis of CHD (e.g., coarctation, transposition of great arteries) and 15 were heart healthy. Five fetuses were excluded due to reduced image quality. In fetuses with CHD compared to healthy controls, median LV GLS (− 13.2% vs. − 18.9%; p < 0.007), RV GLS (− 7.9% vs. − 16.2%; p < 0.006), and LV strain rate (1.4 s−1 vs. 1.6 s−1; p < 0.003) were significantly higher (i.e., less negative). LV radial strain was without a statistically significant difference (20.7% vs. 22.6%; p = 0.1). Bivariate discriminant analysis for LV GLS and RV GLS revealed a sensitivity of 67% and specificity of 93% to differentiate between fetuses with CHD and healthy fetuses. Conclusion Myocardial strain was successfully assessed in the human fetus, performing dynamic fetal cardiac MRI with DUS gating. Our study indicates that strain parameters may allow for differentiation between fetuses with and without CHD. Clinical relevance statement Myocardial strain analysis by cardiac MRI with Doppler ultrasound gating and feature tracking may provide a new diagnostic approach for evaluation of fetal cardiac function in congenital heart disease. Key Points • MRI myocardial strain analysis has not been performed in human fetuses so far. • Myocardial strain was assessed in human fetuses using cardiac MRI with Doppler ultrasound gating. • MRI myocardial strain may provide a new diagnostic approach to evaluate fetal cardiac function.

“…6 (2) The measurements can be obtained using the area and distance measurement tools available on all ultrasound machines and do not require speckle tracking analysis to perform as they have a high correlation for the LV area (0.96), RV area (0.98), LV length (0.97) RV length (0.97) LV midchamber width (0.95), and RV Base width (0.93) when compared to speckle tracking measurements. 10,24 (3) The measurements take less than 1 minute to perform once the end-diastolic image of the 4-chamber view is obtained. Supplement 3 is a video of the measurements from a fetus at 20 weeks and 1 day that took 48 seconds to complete the measurement sequence.…”

“…The clinical benefits of measuring the 4CV and ventricles, as described in the current study, are the following: (1) The measurements would be compatible with the guidelines outlined for the Standard Ultrasound Examination endorsed by AIUM, ACOG, ARC, SMFM, and SRU 6 . (2) The measurements can be obtained using the area and distance measurement tools available on all ultrasound machines and do not require speckle tracking analysis to perform as they have a high correlation for the LV area (0.96), RV area (0.98), LV length (0.97) RV length (0.97) LV mid‐chamber width (0.95), and RV Base width (0.93) when compared to speckle tracking measurements 10,24 . (3) The measurements take less than 1 minute to perform once the end‐diastolic image of the 4‐chamber view is obtained.…”

Objectives The prenatal detection of D‐Transposition of the great arteries (D‐TGA) and tetralogy of Fallot (TOF) has been reported to be less than 50% to as high as 77% when adding the outflow tracts to the four‐chamber screening protocol. Because many examiners still struggle with the outflow tract examination, this study evaluated whether changes in the size and shape of the heart in the 4CV as well as the ventricles occurred in fetuses with D‐TGA and TOF could be used to screen for these malformations. Methods Forty‐four fetuses with the pre‐and post‐natal diagnosis of D‐TGA and 44 with TOF were evaluated between 19 and 36 weeks of gestation in which the 4CV was imaged. Measurements of the end‐diastolic width, length, area, and global sphericity index were measured for the four‐chamber view and the right and left ventricles. Using z‐score computed values, logistic regression was performed between the 88 study and 200 control fetuses using the hierarchical forward selection protocol. Results Logistic regression identified 10 variables that correctly classified 83/88 of fetuses with TOF and TGA, for a sensitivity of 94%. Six of 200 normal controls were incorrectly classified for a false‐positive rate of 3%. The area under the receiver operator classification curve was 98.1%. The true positive rate for D‐TGA was 93.2%, with a false‐negative rate to 6.8%. The true positive rate for TOF was 95.5%, with a false negative rate of 4.5%. Conclusions Measurements of the 4CV and of the RV and LV may help identify fetuses at risk for D‐TGA or TOF.
