“…When comparing the reservoir strain for the free wall from a study by Dahlback, z ‐scores were within 1 z ‐score value of the current study for the LA ( Z = −0.79) and RA ( Z = −0.43) 36 . In the study by Rato, their results for the global reservoir strain were within 1 z ‐score value of the current study for the LA ( Z = −0.96) and the RA ( Z = 0.10) 35 …”

“…They reported the mean values for the reservoir strain to be significantly higher for the RA than the LA (33.9 versus 30.3%). 35 While the current study found no significant difference between the RA and LA reservoir strains, their mean values fell within 1 z-score of the current study. They also reported a significant correlation between frame rate and RA and LA reservoir strain.…”

“…While the above measurements evaluated ventricular systolic function, the only diagnostic tools used to examine atrial function have been pulsed Doppler measurements of blood flow into the ventricles acquired just below the atrioventricular valves (E and A waveforms), as well as the basilar movement of the ventricular and septal walls (e′ and a′) 33,34 .

Objectives The purpose of this study was to use speckle tracking analysis to evaluate the size, shape, and function of the atrial chambers in normal fetuses and develop a z‐score calculator that can be used in future studies in fetuses at risk for cardiovascular disease. Methods The control group consisted of 200 normal fetuses examined between 20 and 40 weeks of gestation in which speckle tracking analysis of right (RA) and left (LA) atrial chambers was performed. The atrial end‐diastolic and end‐systolic endocardial borders for each chamber were identified from which measurements of atrial length, width, area, and volume were computed. Equations were derived using fractional polynomial regression analysis to compute z‐score equations. Results The LA end‐diastolic volume, RA and LA end‐diastolic area, length, base width, and mid‐chamber widths increased with gestational age and fetal size. Left atrial emptying and ejection volumes increased with gestational age and fetal size. The fractional area change was significantly less for the RA than the LA. The LA base and mid‐chamber fractional shortening were significantly greater than the RA. There was a significant difference between the RA and LA global contractile strain. Conclusion Mean and standard deviation equations for each of the measurements described in this study were computed to create a z‐score calculator that can be utilized in the clinical environment when evaluating fetuses with suspected atrial pathology that could alter the size, shape, and function of the atrial chambers.

While Maternal Diabetes Mellitus (DM) is well known to affect the size and function of multiple fetal organ systems, effects on developing heart chamber function remain difficult to assess. We sought to determine the independent impact of maternal DM on fetal cardiac function in middle pregnancy. We prospectively recruited mothers with all categories of DM and non-diabetic healthy controls (NDC). Echocardiograms were optimized for chamber quantification and strain analysis. Left atrial area (LAA), LA strain (LAS), right atrial strain (RAS), global longitudinal ventricular strain (GLS) and Right ventricular free wall strain (RV FWS) were evaluated by 2 blinded operators. After excluding 9 mothers with poor fetal image quality, images from 104 mothers with DM and 47 NDC were analyzed. Mothers with DM and NDCs were well matched for age, blood pressure, smoking prevalence, and gestational age. Fetal heart rate (FHR) was significantly higher in fetuses of mothers with DM compared to NDC (147 ± 10 bpm vs. 144 ± 8, p = 0.04). LAA in fetuses of mothers with DM trended towards being larger in size (1.68 ± 0.4cm2 vs. 1.56 ± 0.4cm2, p = 0.08). Fetal septal diameters were larger in maternal DM compared to NDC (2.7 ± 0.5 cm vs. 2.5 ± 0.5 cm, p = 0.001). GLS was similar between the groups. Fetal LAS was lower in maternal DM (28.8 ± 8.8% vs. 33.3 ± 10.4%, p = 0.007) and was independently associated with maternal DM after adjusting for GLS and FHR. Fetal RAS was lower in maternal DM (27.7 ± 10.4% vs. 31.8 ± 10.3%, p = 0.007), however only determinates were estimated fetal weight and RV FWS. Maternal DM independently impairs fetal LA function in mid pregnancy. These early functional changes in the developing heart warrant future studies investigating impact on cardiovascular health.
