  Fig. 1 Transthoracic echocardiography apical 4-chamber view revealing a complex membrane (arrow) with its septum (arrowhead) subdividing the LA into two chambers (A). Cardiovascular magnetic resonance 4-chamber steady-state free precession image showing the membrane (arrow) with its septum (arrowhead) (B). Transesophageal echocardiogram mid-esophageal 4-chamber (C) and modified 2-chamber (D) views demonstrating the membrane which is attached to the coumadin ridge just below the left pulmonary veins (D). LA: true left atrium, LV: left ventricle, PVC: pulmonary venous chamber, RA: right atrium, RV: right ventricle.

• 

  Fig. 2 Transesophageal echocardiogram modified mid-esophageal views showing the lateral (A) and medial (B) attachments of the membrane with color turbulence and possible multiple fenestrations (B, arrows). Continuous wave Doppler through the lateral edge of the membrane showing significant gradient across, both systolic and diastolic (C). PVC: pulmonary venous chamber.
