[Parietal fibroplastic endocarditis]

Parietal fibroplastic endocarditis is commonly observed in two main diseases: Löffler' endocarditis and Davies' endomyocardial fibrosis. Endocarditis' damage is explained by the cytolytic effects of basic proteins present in eosinophil granules (major basic protein and cationic protein); long standing and amount of eosinophilic cells condition anatomic lesions. The clinical features are explained by the ventricular seat of endocarditis lesions (right, left, or both). They include in all cases: tricuspid and/or mitral insufficiency, adiastolic syndrome. Two-dimensional echocardiography has improved the diagnosis; ventricular angiocardiography remains the reference examination. Prognosis has been largely improved these recent past years by surgical endocardiectomy and valvular conservative surgery among children.
