[Restrictive cardiomyopathy as a late sequel of influenza A2 virus myocarditis]

A clinically acute myocarditis with an increase of the influenza A2-virus titer marks the beginning of a ten year history leading to a restrictive cardiomyopathy, complicated by an exudative enteropathy. Two serial endomyocardial biopsies reveal an increasing interstitial fibrosis. Virus myocarditis as a cause of restrictive cardiomyopathy, which corresponds to the old term "myocardial fibrosis", is discussed.
