“…16,[20][21][22] Vendor-dependent speckle tracking imaging is usually based on grayscale B-mode images of endocardial and/or epicardial borders. [27][28][29][30][31] The objective of our study was to compare left (LV) and right ventricular (RV) global and segmental longitudinal peak systolic strain (LPSS) values acquired with two different frame rates (30 and 60 fps). Based on the motion vectors, which indicate displacement, other parameters like strain can be defined.…”

“…24 At the present time, fetal studies using 2D CPA have focused on the 4-chamber view, analyzing either the left or right ventricular chambers. [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43] Therefore, the nomenclature for segmental analysis has to be reconsidered to include the ventricular basal lateral wall and septum, the mid lateral wall and septum, and the apical lateral wall and septum for both right and left ventricles (Figure 8). When the heart is oriented with the apex in the oblique or perpendicular positions, the full thickness of the walls and septum may be imaged and the endocardium clearly delineated.…”

“…25 Two-dimensional speckle-tracking analysis of the fetal heart has been of interest to investigators since 2005. [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43] Although there have been differences in equipment and findings, this technology has the potential for broad application in fetal medicine. Deformation analysis has been evaluated in fetuses with twin-twin transfusion syndrome, intrauterine growth restriction, maternal diabetes, as well as other fetal conditions.…”

Various approaches to 2‐dimensional speckle tracking have been used to evaluate left ventricular function and deformation in the fetus, child, and adult. In 2015, because of differences in imaging devices and analytical programs, the cardiology community published a consensus document proposing standards for pediatric/adult deformation imaging using 2‐dimensional speckle tracking. The understanding and application of deformation imaging in the fetus have been limited by a lack of uniform software, terminology, techniques, and display. This article provides a practical, step‐by‐step approach for deformation analysis of the fetal heart using offline software that is independent of specific ultrasound vendors.

“…Recently, speckle tracking has been reported to be of value for assessing movement of heart walls [21]. This technique calculates the local velocity and strain in tissue by following the movement of a punctate structure (speckle pattern) in each frame during the B-mode method [22].…”

Prenatal ultrasound screening has allowed for the detection of in utero cardiac abnormalities. Specifically, distinction is possible between ventricular diverticula and aneurysms, which is important because each condition has a different clinical outcome. We report the case of a 35-year-old, gravida 1, para 1 woman, with no significant past medical history, who underwent routine prenatal ultrasound screening at 32 weeks' gestation. A four-chamber ultrasound of the fetal heart combined with M-mode echocardiography showed abnormal dilatation of the right ventricular chamber measuring 2.2 cm × 1.0 cm but with normal contractility. Delivery was performed at full term by cesarean section, and a right ventricular diverticulum was confirmed by postnatal cardiac computed tomography. The baby developed normally with no cardiac sequelae during followup. This case demonstrates the importance of making a correct diagnosis of ventricular diverticula by prenatal ultrasound when abnormal dilatation of the fetal ventricle is identified during routine screening. Because evaluating the wall contractility by M-mode ultrasound leads to evaluating whether it has the myocardium, we conclude that M-mode echocardiography is effective for the purpose of prenatal cardiac diagnosis and can distinguish between ventricular aneurysms and functioning ventricular diverticula.
