    Abstract:
    An effusive-constrictive pericarditis confined to the epicardium is extremely rare in childhood. We report case of a 7-year-old boy with such a condition. During an annual school health examination, he was found to have low voltage activities on electrocardiogram. On admission, physical examination showed markedly distended abdomen due to ascites and hepatomegaly. Two-dimensional echocardiography revealed small ventricular cavities, extremely dilated inferior vena-cava, and a moderate amount of pericardial fluids. Pericardial and epicardial thickening were also suspected. Retrospectively, epicardial thickening was suspected on computed tomogram as well. Cardiac catheterization showed a typical diastolic dip and plateau pattern on the right ventricular pressure tracing, and deep x and y descents on that of the right atrium, suggesting that not pericardial effusion, but pericardial thickening mainly contributed to the cardiac dysfunction. Pericardiocentesis did not improve the clinical symptoms and high central venous pressure. On thoracotomy, we unexpectedly found intact pericardium and fibrotic epicardium covering the whole heart, so epicardiectomy was performed. Despite the fact that most of the fibrotic epicardium was removed, there were no immediate responses such as decrease in central venous pressure within the first 5 days after the surgery. Furthermore, it was not until two months later that all symptoms and hemodynamic parameters returned to normal levels. There have been several case reports of isolated epicardial constriction associated with pericardial effusion in English literature. However, we are unaware of such a report n Japanese. We concluded that it is important to evaluate the hemodynamics before and after pericardiocentesis, and to detect peri-and/or epicardial thickening by serial echocardiography and CT scan.(ABSTRACT TRUNCATED AT 250 WORDS)
