Abstract
This report presents a case of aortic valvular dysfunction and right coronary artery disease following radiation therapy on the mediastinum. A 61-year-old woman had received mediastinal radiation for the treatment of right mammary cancer 20 years previously. She developed symptoms of congestive heart failure 6 months ago. The patient was found to have aortic valvular dysfunction and proximal stenosis of the right coronary artery. Surgical aortic valve replacement improved cardiac status, and vasodilator treatment reduced ischemia due to right coronary artery stenosis.
