Abstrakt: Radiotherapy may affect the heart in several ways. We describe a child who had pulmonary edema caused by severe mitral regurgitation after thoracic radiotherapy for a Ewing sarcoma. Transesophageal echocardiography demonstrated this to be caused by an immobilized posterior leaflet, and valve replacement was necessary. This is the first reported patient with rapid progression to severe valvar disease after radiotherapy and in whom this novel mechanism has been demonstrated.
