Figure 2: Two-dimensional (a) and two-dimensional color flow Doppler (b) echocardiography images in four chamber views from the apical window. (a) The cor-triatriatum dexter membrane (arrows) which is partially prolapsing across the tricuspid valve to the right ventricle during diastole. (b) Eccentric tricuspid valve inflow (red color) from the outer part of the right atrium to right ventricle. The blue color represents the systemic venous blood flow that is diverted back to right atrium by the cor-triatriatum dexter membrane. LA: Left atrium, LV: Left ventricle, RA: Right atrium, RV: Right ventricle
