Introduction:
Myopericarditis is an rare form of Horton disease. We report two new cases.
Method:
Two patients, more than 60-years-old, had developed global cardiac insufficiency with predominant left insufficiency, with physical alteration and biological inflammation. Echocardiography revealed a myopericarditis. Bacteriological explorations were all negative. In the two cases, temporal artery biopsy revealed giant cell arteritis. Treatment with oral corticosteroids improved biological and clinical symptoms.
Conclusion:
Myopericarditis is a rare form of Horton disease. Classical clinical presentation is rarely associated. Temporal artery biopsy is essential in confirming and proposing a specific therapy, in order to prevent cardiovascular ischemic complications.
