This report presents a case of occult constrictive pericarditis and mitral
valve insufficiency following chest radiotherapy. A 44-year-old man had rec
eived radiotherapy for the treatment of Hodgkin's disease 8 years ago. At a
ge 40 years, effusive pericarditis occurred and he was treated with intrape
ricardial drainage. Biopsy revealed a fibrotic and thickened pericardium. H
e developed congestive heart failure 3 years later. The patient was found t
o have occult constrictive pericarditis and mitral valve insufficiency. He
underwent mitral valve replacement, tricuspid annul plasty, and pericardiec
tomy. Although there is the benefit of cure for the Hodgkin's disease, the
prognosis after treatment is affected by radiotherapy-induced heart disease
. After radiotherapy of the chest and mediastinum, long-term cardiological
follow-up is recommended in order to detecting patients with radiation-indu
ced heart disease, such as the present case.
