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.
