Abstract

We investigated the effect of fetal sheep ductus arteriosus occlusion (DO) on the distribution of cardiac output and left and right ventricular function by tissue and pulsed Doppler at baseline; after 15 and 60min of DO induced with a vascular occluder; and 15min after release of DO. Ductal occlusion decreased fetal pO2. Mean left ventricular output increased (p
