Holy Grail Deformity of Distal Disc Hubless Atrial Septal Occluders in Pediatric Hearts

A special deformity associated with the use of left atrial disc hubless atrial septal occluders has been described in 3 children. This chalice-shaped deformity that occurred during the use of Occlutech and Lifetech septal occluders was given the name "Holy Grail Configuration". Despite being easily reversible, reduction of the metal load on the left atrium has been suggested to have some negative effects.
