Identification of cardiovascular abnormalities in children with empyema thoracis by two-dimensional and Doppler echocardiography.
To our knowledge, echocardiographic assessment of children with empyema has not been reported previously in the literature. Two-dimensional and Doppler echocardiography were performed in 47 children with acute (n = 23) and chronic (n = 24) empyema and 34 control subjects. Echocardiography demonstrated pericardial effusion in 11 of 47 patients (23 percent). Those with acute empyema had significantly thicker pericardium (p < 0.009) than control subjects. Tricuspid regurgitation was present in 21 of 47 patients (45 percent). The mean right ventricular internal dimension in diastole was significantly larger in patients with acute (p < 0.00002) and chronic (p < 0.006) empyema than that of control subjects. The mean tricuspid pressure gradients indicated an elevated mean right ventricular systolic pressure with increased calculated mean pulmonary arterial systolic pressures of children with acute empyema (38.5 +/- 6.4 mm Hg) and chronic (39.8 +/- 5.6 mm Hg) empyema than the normal mean (20 +/- 4 mm Hg). Children with chronic empyema had significantly less mean left ventricular internal dimension in diastole (p < 0.005) and left ventricular internal dimension in systole (p < 0.02) than control subjects. Strikingly, their mean left ventricular mass was also significantly less (p < 0.05) than that of subjects with either acute empyema or control subjects. These results provide baseline data for follow-up of children with acute and chronic empyema.
