Figure 1

Doppler echocardiographic images of ductal systolic and diastolic velocities and right-to-left ventricular dimension ratio in a 29-week fetus whose mother was a heavy green tea consumer. (a) Two-dimensional echocardiographic image of the ductus arteriosus (arrow). (b) Pulsed Doppler spectrum of the ductal flow showing systolic (1.19 m/s) and diastolic (0.20 m/s) velocities in their upper limits. (c) Two-dimensional images of the ventricles showing an increased right-to-left ventricular dimension ratio (1.4). PA, pulmonary artery; Desc Ao, descending aorta; LV, left ventricle; RV, right ventricle; RA, right atrium; LA, left atrium; DUCTUS ART, ductus arteriosus.
