Transthoracic echocardiography in apical 4 chamber (A4C) view showing left atrium (LA) divided into 2 chambers LA1 and LA2 by a membrane (A) with color Doppler showing pulmonary venous return progressing from proximal left atrium to left ventricle through the membrane (arrow) (B). Modified A4C view opening up the 3rd LA chamber (LA3) separated from LA2 by the supramitral ring with color Doppler showing flow through the supramitral ring (C, D). Modified A4C view showing all 3 LA chambers with LA2 communicating with right atrium through the atrial septal defect (E, F). The thicker arrow shows predominant right to left shunt, and the thinner arrow shows the small left to right shunt. RA, right atrium; LA, left atrium; RV, right ventricle; LV, left ventricle
