Cupping of the left atrial disc is a novel echocardiographic sign of ASD-device mismatch that may necessitate surgical extraction.
May prompt enhanced echocardiographic surveillance after ASD closure; leaves open the utility of left atrial disc cupping as a mismatch marker.
We report a case of percutaneous atrial septal defect closure (ASD) in which, despite careful device selection and successful shunt closure, a number of adverse echocardiographic features developed, necessitating surgical extraction of the device and patch closure of the defect. Lessons regarding case selection, device choice, appropriate follow-up and recognition of adverse echocardiographic features can be learned from this experience.
