Can two-dimensional Doppler echocardiography effectively assess fetal cardiac hemodynamics in utero?
Two-dimensional Doppler echocardiography is a useful modality for assessing in utero fetal cardiac hemodynamics and identifying physiologic and pathologic states.
Variable detection rates support selective fetal flow assessment; leaves open standardization and validation before broader clinical use.
Forty‐one 2‐dimensional (2‐D) Doppler echocardiographic examinations were performed on 36 fetuses in utero, at 17 to 39 weeks of gestation. Left and right transvalvular, aortic, pulmonary, transforaminal, and inferior vena caval flows were assessed. The rates of detection of left and right transvalvular, aortic, pulmonary, transforaminal, and inferior vena caval flows were 85.4, 73.2, 53.7, 41.5, and 9.8%, respectively. In one fetus with premature atrial contraction, there was a characteristic pattern of intracardiac hemodynamics. The 2‐D Doppler echocardiography is proving to be very useful for assessing in utero fetal cardiac hemodynamics and determining related physiologic and pathologic states.
