title: Steerable control of the eustachian valve during transcatheter closure of secundum atrial septal defects.
abstract: Over the past decade there has been increased use of transcatheter devices for closure of secundum atrial septal defects. The presence of a large eustachian valve complicating transcatheter closure has not been described. We describe four patients with prominent eustachian valves, in three of whom we employed a simple technique to obtain control of the eustachian valve during device placement using transesophageal echo guidance.
