Double Interatrial Septum and Patent Foramen Ovale in Woman With Transient Ischemic Attack
Two-dimensional transthoracic echocardiogram (apical 4-chamber view) shows 2 parallel atrial-septal structures.
LA = left atrium; LVOT = left ventricular outflow tract; RA = right atrium
Supplemental motion image is available for Figure 1.
Two-dimensional transesophageal echocardiogram in color-flow Doppler mode (midesophageal short-axis view at aortic valve [AV] level) shows flow from the interatrial chamber (arrow) to the right atrium (RA) through a patent foramen ovale (asterisk).
LA = left atrium
Two-dimensional transesophageal echocardiogram (midesophageal bicaval view) shows 2 parallel interatrial septa.
LA = left atrium; RA = right atrium; SVC = superior vena cava
Three-dimensional transesophageal echocardiograms in A) modified midesophageal long-axis and B) midesophageal views show 2 parallel interatrial septa enclosing an additional interatrial chamber (arrows)
LA = left atrium; RA = right atrium
Supplemental motion image is available for Figure 4B.
