title: [Löffler's parietal fibroplastic endocarditis. Echocardiographic course over 5 years].
abstract: METHODS
  A 28-year-old man, who had sustained a traumatic displaced fracture of the left lateral clavicle requiring operative realignment, was admitted to hospital because of the incidental finding of pathological electrocardiographic findings (suggestive of past anterior myocardial infarction). He had dyspnoea on effort and episodes of irregular tachycardia without other cardiac symptoms, as well as regular tachycardia (120/min) without pulse deficit. Body temperature was 37.3 degrees C, blood pressure 110/70 mm Hg.
  
  
  METHODS
  Transoesophageal echocardiography showed regular myocardial contractility but a 3.27 cm cap-like area of echo-poor and echo-dense layers at the left ventricular apex. There was leucocytosis (25,400/microliter) with 45% eosinophilia (11,430/microliter). IgE was raised to 134.6 kU/l. Bone marrow smear showed marked eosinophilic but little neutrophilic hyperplasia. Parasitic infection was excluded.
  
  
  METHODS
  The clinical and echocardiographic findings suggested the diagnosis of Löffler's eosinophilic endocarditis (endomyocardial fibrosis), later confirmed histologically. After initial treatment, first only with cortisone then also hydroxyurea, the eosinophilia finally responded to combined cortisone and interferon alpha 2. The dosage schedule was governed by the clinical and echocardiographic findings. In the further course of the disease there occurred progressive heart failure with severe tricuspid and mitral regurgitation, secondary pulmonary hypertension and severe fibrosis of both ventricles, 41 months after diagnosis the patient underwent tricuspid and mitral valve reconstruction with removal of the endocardial fibrotic layers. Follow-up examinations found the cardiac condition to be adequately controlled without further cardiac infiltration since 20 months.
  
  
  CONCLUSIONS
  Echocardiography, in conjunction with the clinical findings, provides a firm foundation for successfully treating Löffler's endocarditis. In selected cases cardiac surgery can markedly improve the course.
