title: [Cardiac manifestations of the hypereosinophilic syndrome. The value of 2-dimensional echography (12 cases)].
abstract: The prognosis of the hypereosinophilic syndrome (HS) depends mainly on the development of endomyocardial fibrosis (EMF). This complication may be overlooked at an early stage, although its presence is an indication for steroid or antimitotic therapy of the HS. Even at an advanced EMF and associated intracardiac thrombi may not be visualised by angiography. This study was undertaken to assess the diagnostic value of 2D echocardiography in 12 patients. The patients were all men (12 of them) aged 22 to 64 years with unexplained eosinophilia 1 500/mm3 for over 6 months, and visceral lesions. The patients were divided into 3 clinical groups. Group A comprised 4 "allergic" patients with chronic asthma and a significant elevation of IgE; Group B comprised 5 "myeloproliferative" patients with splenomegaly and/or hepatomegaly and a significant elevation of serum B12 levels. The 3 remaining patients who could not be allocated to either Group A or B formed the third group (Group C). 2D echocardiography was carried out on average 30 months after diagnosis of the HS and six planes of examination were used systematically (two parasternal, two apical, one extreme apical and one subcostal). Right and left ventriculography was performed in 6 patients (less than one month before or after 2D-echo). Anatomical studies were obtained in 4 cases (2 operations, 3 autopsies). Echocardiographic signs of EMF were observed in 8 cases. Four patients had a restrictive cardiopathy associated to a large LV thrombus in 2 cases.(ABSTRACT TRUNCATED AT 250 WORDS)
