Ostium secundum atrial septal defect (osASD) is a common congenital heart disease and transcatheter closure is the preferred treatment. Late device-related complications include thrombosis and infective endocarditis (IE). Cardiac tumours are exceedingly rare. The aetiology of a mass attached to an osASD closure device can be challenging to diagnose.
