Ostium secundum-type atrial septal defect closure has evolved from a surgical procedure requiring cardiopulmonary bypass to a percutaneous, catheter-based procedure usually requiring only an overnight hospital stay. The overall safety and effectiveness has compared favorably with surgical repair. Although rare, complications have been described, including erosion, device embolization, or malfunction and arrhythmias. The overall long-term clinical outcomes have been excellent: good quality of life, functional class improvement, and ventricular remodeling have been the rule after the procedure. It is mandatory to recommend indefinite follow-up of patients undergoing this procedure for potential long-term complications.
