The 24‐Segment Sphericity Index: A New Technique to Evaluate Fetal Cardiac Diastolic Shape

Because of parallel circulation in the fetus and the differential effect that various disease states may have on the shape of the right and left ventricles, this study was conducted to evaluate the sphericity index (SI) of 24 transverse segments distributed from the base to the apex of each of the ventricular chambers.

Evaluation of the right and left ventricles: An integrated approach measuring the area, length, and width of the chambers in normal fetuses

The purpose of this study was to simultaneously measure with speckle tracking software the end‐diastolic ventricular area (A), basal transverse width (BW), mid‐chamber transverse width (MW), and basal‐apical length (BAL) in normal fetuses and those with pathology.

Longitudinal Annular Systolic Displacement Compared to Global Strain in Normal Fetal Hearts and Those With Cardiac Abnormalities

The purpose of this study was to compare a new technique that measures the midventricular basal‐apical longitudinal diastolic and systolic lengths, computes the longitudinal displacement fractional shortening, and compares it to global strain.

Twenty‐four Segment Transverse Ventricular Fractional Shortening: A New Technique to Evaluate Fetal Cardiac Function

Because of various fetal and maternal disease states, this study was conducted to evaluate the fractional shortening of 24 transverse segments distributed from the base to the apex of the ventricular chambers.

Quantitative Evaluation of the Fetal Right and Left Ventricular Fractional Area Change Using Speckle Tracking Technology

To measure, using speckle‐tracking technology, the fractional area change (FAC) of the right and left ventricles in normal fetal hearts between 20 and 40 weeks of gestation.

Comprehensive Evaluation of Fetal Cardiac Ventricular Widths and Ratios Using a 24‐Segment Speckle Tracking Technique

This study was conducted to evaluate the 24‐segment transverse widths of the right and left ventricles distributed from the base to the apex of the ventricular chambers and compute the right ventricular (RV)/left ventricular (LV) ratios for each segment.

Evaluation of Fetal Left Ventricular Size and Function Using Speckle-Tracking and the Simpson Rule: Speckle-Tracking Assessment of Left Ventricular Size and Function

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.

Speckle Tracking of the Basal Lateral and Septal Wall Annular Plane Systolic Excursion of the Right and Left Ventricles of the Fetal Heart: Speckle Tracking of the Basal Lateral and Septal Wall Annular Plane

Annular plane systolic excursion (APSE) has been evaluated for the right (RV) and left (LV) ventricles using M‐mode echocardiography. This study examined APSE using 2‐dimensional speckle tracking (2DST) of the lateral and septal annuli of the RV and LV in normal fetuses.

EP03.13: 24-segmental shortening fraction (SF): a new diagnostic tool to evaluate fetal cardiac function.

Results: The SSI was not associated with gestational age. The mean and standard deviation for the 24 segments demonstrated an increase in the SSI from the base to the apex for both ventricles (see figure1). The RV SSI was significantly lower (p < 0.001) than the LV SSI for segments 1 to 18. Fetuses with CHD, early and late-onset growth restriction demonstrated abnormal SSI. Conclusions: The RV SSI is significantly lower than the LV suggesting a more elliptoid shape. Fetuses with CHD as well as early and late onset growth restriction may demonstrate abnormal SSI of the right and left ventricles.
