A 54-year-old male presented with symptoms of dyspnoea, and oedema of the lower extremities. Transthoracic echocardiography (TTE) revealed secondum-type atrial septal defect (ASD). He successfully received a 30-mm Amplatzer ASD closure device percutaneously. Echocardiography immediately after the procedure and the next day showed a well-positioned device. He was discharged the next day on 100 mg aspirin daily and warfarinisation due to atrial fibrillation. A month later, he revisited the hospital due to recurrence of dyspnoea and a grade 2 systolic murmur was heard on the left parasternal border. A chest X-ray showed abnormal location of the closure device and TTE revealed re-appearance of the ASD and an embolised Amplatzer device in the left ventricular outflow tract (LVOT) with partial obstruction. He requested surgery to remove the Amplatzer device and received an ASD patch repair, tricuspid valve repair and modified Maze operation concurrently. He is now in routine follow up without any other complications.
