There are surgical and percutaneous interventional strategies to treat ASD, each with its own advantages and inevitable drawbacks too. Here, we described a case of large size secundum type ASD (30 mm x 31 mm) that first underwent percutaneous closure with ASD Amplatzer device number 33. The day after the procedure, although the patient was asymptomatic, on follow-up echocardiography, it was found that the device was embolized into the right ventricle within Moderator Bands. Hence, the cardiac surgery was performed.
