[Coronary artery stenoses close to the ostia after mediastinal irradiation]

A 42-year-old man who 16 years previously had had mediastinal radiotherapy (total focal dosage of 52 Gy) for a malignant lymphoma, developed chest pain on mild exertion. Coronary arteriography during a diagnostic cardiological work-up revealed a 50-70% stenosis of the right coronary artery near its origin and a 90% stenosis in the main left coronary artery. Except for being slightly over-weight (85 kg at a height of 181 cm) there were no risk factors for coronary heart disease and there was no evidence for arterial disease elsewhere. A double aortocoronary vein graft was placed to the right coronary artery and the interventricular branch of the left coronary artery. The postoperative course was unremarkable and the patient has resumed his occupation. This report emphasizes that, in case of atypical chest pain after mediastinal radiotherapy, coronary heart disease as a late complication should be considered.
