Case Reports
Surgical removal of an atrial septal occluder device embolized to the main pulmonary artery.
Percutaneous closure of atrial septal defects in adults has emerged as an alternative to surgery. We report a sequela of such closure in a 16-year-old boy: embolization of the atrial septal defect occluder into the main pulmonary artery when the patient experienced an episode of intense coughing immediately after device deployment. We removed the device surgically and closed the atrial septal defect in a standard manner, with an autologous pericardial patch.

Mediastinal schwannomas are sometimes diagnosed as pericardial or bronchogenic cysts, if cystic degeneration is extensive. When mediastinal schwannomas are not diagnosed as primary cardiac tumors, the use of cardiopulmonary bypass in their resection appears to be infrequent. We report the case of a 48-year-old woman who presented with symptoms from a suspected intrapericardial cyst. ⋯ After complete resection with the use of cardiopulmonary bypass, the mass was identified as a benign extracardiac schwannoma. More than 3 years postoperatively, the patient had no relevant symptoms. We discuss the preoperative diagnosis, the method of resection, and our broad strategy for dealing with such a case.
