title: [Significance of lymphoplasmocytic infiltration in arrhythmogenic right ventricular dysplasia. Apropos of 3 own cases and review of the literature].
abstract: Three patients with typical histological signs of arrhythmogenic right ventricular dysplasia progressed to fulminating heart failure in 1 case and unexplained sudden death in the other two. There were signs of superacute myocarditis in the first case, previous healed pericarditis in the second and chronic myocarditis in the third case. These cases suggested the presence of an inflammatory process complicating the substrate of the dysplasia. Arrhythmogenic right ventricular dysplasia seems to be a developmental defect which is complicated in 50 to 70% of patients, according to a review of 74 cases reported in the literature, by a varying degree of myocarditis suggesting particular susceptibility of these patients to infection and explaining the presence of unusual amounts of fibrous tissue in some and the so called "progressive" nature of the disease in other patients.
