: In a randomized, controlled trial, the Occlutech Figulla Flex II occluder was shown to be noninferior to the Amplatzer Septal Occluder. Both devices provided greater than 90% efficacy, with limited residual shunting and major complications. Although the risk of overall device erosions was low, larger and longer-term studies are needed to distinguish the differences between devices.
