Echocardiography of the fetal heart in TGA IVS and RAS before and after fetal balloon atrial septostomy (BAS). Panel A and C represents limited blood flow across the small FO prior to BAS. Panel B and D represents blood flow across the restrictive FO and additional superior atrial communication (AC) after BAS. Panel A and B were acquired using 2-D echocardiography and Panel C and D were acquired using 3-D echocardiography. TGA, transposition of the great arteries; IVS, intact ventricular septum; RAS, restricted atrial septum; FO, foramen ovale; SVC, superior vena cava; TV, tricuspid valve
