Abstract

Percutaneous device closure of atrial septal defect (ASD) is an alternative treatment to surgery. The main advantages of the percutaneous approach include avoidance of surgery, short procedure time and hospital length, in addition to comparable rates of complications. However, percutaneous device closure is associated with infrequent early and late complications including device embolization, air embolism, cardiac tamponade and thrombotic complications. We report a rare complication of silent and late device embolization of the ASD occluder device into the right pulmonary artery, three months after implantation.
