Figure and video legends
Figure 1A, Video 1 shows mid-esophageal TEE 0-degree view
demonstrating a borderline mitral rim, with a prominent Eustachian valve
very close to the mitral rim in contact with the interatrial septum. The
arrow shows the prominent Eustachian valve. Figure 1 B, C shows the
other rims of the ASD in mid-esophageal TEE 45 degrees and 90 degrees
views which appeared adequate for device closure.
Figure 2 A : Illustration demonstrating right atrium, left
atrium, atrial septal defect and the prominent Eustachian valve, with a
small mitral rim.
Figure 2 B : Illustration to show the device position in
relation to the mitral rim and the arrow shows the line of pressure
exerted by the device. The Eustachian valve adjacent to mitral rim
provides added support in this area.
Figure 3 A-B, Video 2 shows the septal occluder in situ with
the rims within the discs and a prominent EV in mid esophageal TEE 0
degree and 45 degrees respectively.
