Résumé :

Introduction Pericarditis are frequently associated with some degree of concomitant myocardial involvement. Predominant pericarditis with limited myocardial involvement are named myopericarditis. Data regarding myopericarditis are scarce. Patients and methods Retrospective chart review of all patients admitted between 2002 and 2011 with magnetic resonance imaging confirmed myopericarditis. Results Twenty-seven patients were included. Eighty-one percent were men, with median age of 32 years. Infectious disease preceded hospitalization in 55% of cases. Mean left ventricle ejection fraction at admission was 55% with focal myocardial impairment mainly localized in lateral and inferior walls. Coronary angiogram was performed in 37% of cases to rule out an ischaemic aetiology. We identified 5 cases (19%) of myopericarditis preceded by an episode of streptococcus group A throat infection. Non-sustained ventricular tachycardia was observed in 15% of cases. After a 2-year follow-up period, mortality rate was zero and recurrence rate was 15%. Conclusions In our series, myopericarditis was a benign disease affecting mostly young men, and prognosis was good. A significant proportion of cases was preceded by group A streptococcus infection.
