Figure 1: Two-dimensional (a) and two-dimensional color flow Doppler (b) echocardiography images from the sub-costal window. (a) The cor-triatriatum dexter membrane (arrows) that separates the right atrium into two parts. The inner part of right atrium receives the systemic venous blood from superior vena cava and inferior vena cava which is directed by the cor-triatriatum membrane to the left atrium via the foramen ovale. (b) The right to left shunt (blue color) across the foramen ovale. RA: Right atrium, SVC: Superior vena cava, IVC: Inferior vena cava, LA: Left atrium, FO: Foramen ovale
