Assessment of fetal intraventricular diastolic fluid dynamics using ultrasound vector flow mapping.

ABSTRACT:

Objective

The purpose of this study was to investigate the feasibility of visualizing and quantifying the normal pattern of vortex formation in the left ventricle (LV) and right ventricle (RV) of the fetal heart during diastole using vector flow mapping (VFM).

Methods

A total of 36 healthy fetuses in the second trimester (mean gestational age: 23 weeks, 2 days; range: 22-24 weeks) were enrolled in the study. Color Doppler signals were recorded in the four-chamber view to observe the phase of the diastolic vortices in the LV and RV. The vortex area and circulation were measured, and parameters such as intraventricular pressure difference (IVPD), intraventricular pressure gradient (IVPG), and average energy loss (EL_AVG) were evaluated at different diastolic phases, including
