echocardiographic guidance during fetal atrial septal stent placement for fetus with severe aortic stenosis and evolving hypoplastic left heart syndrome (HLHS)
a needle is advanced into the uterus, across the placenta, through the fetal chest wall and into the right atrium

a wire is placed through the needle into a left pulmonary vein
the stent will ultimately be advanced onto the wire and positioned across the atrial septum
