[Calcific constrictive pericarditis of anginal form complicated by hemopericardium and tamponade during anticoagulant treatment].

The case-history of a patient with calcified constrictive epicardopericarditis with rapidely progressive aggravation after digestive hemorrage due to excessive dose or oral anticoagulant therapy is reported. The occurrence of a cardiac tamponade has necessitated pericardectomy which has permitted to detect a partitionned hemopericardium. The surgical act was followed by gross improvement of both constrictive phenomenon and angina pectoris which have grounded the prescription of anticoagulant therapy. Anticoagulant therapy is likely responsible of the hemopericardium. Such facts are exceptionals in the course of constrictive pericarditis; diagnostic and therapeutic problems related to this complication are studied. The question of angina pectoris in the course of acute and chronic pericarditis is briefly studied by the way of this observation. Attention is drawed on the danger of the prescription of anticoagulant therapy in the course of some constrictive pericarditides.
