title: Surgery for radiation-induced valvular disease.
abstract: The effects of radiation on the heart have been well described including acute and chronic pericarditis, myocardial fibrosis, accelerated arteriosclerosis of the coronary arteries. However, valvular dysfunction secondary to mediastinal irradiation has received less attention. We report two cases who developed valvular dysfunction associated with coronary artery disease possibly caused by mediastinal irradiation and a review of the literature regarding surgery for radiation induced valvular disease. Both patients underwent aortic valve replacement and coronary artery bypass graft surgery. With increasingly prolonged survival following mediastinal irradiation, we believe that long term follow up in patients who receive mediastinal irradiation is indicated.
