Movie clips 1 and 2 Apical four-chamber view of transthoracic echocardiography (two dimensions and color). A very redundant, thin, freely mobile transverse membrane inside the right atrial cavity that seems to divide the right atrium into the two chambers during the right ventricle systolic phase and the right ventricle diastolic phase, the Chiari network is entrapped in the right ventricle, and the picture may mimic Ebstein’s anomaly. The blood flow goes around the Chiari network in the diastolic phase without obstruction. (AVI 658 kb)

Movie clips 3 and 4 Subcostal short-axis view of transthoracic echocardiography (two dimensions and color). The Chiari network is attached to the superior of the right atrium (RA) near the orifice of the superior vena cava. The blood flow from superior vena cava (SVC) and the inferior vena cava (IVC) trapped by the Chiari network (CN) was guided to the patent foramen ovale (PFO) in the color Doppler. (AVI 783 kb)
