What Does This X-ray Report For Pericardial Effusion Indicate?

My two year old.daughter had an.xray today for pericardial effusion-thrombocytopenia NYD anemia hypoalbunemia/percardial drain insert (08/01) alteplase/broviac insert-cxr today re: f/u pericardial effusion.
Results are
Slight prominence in pulmonary vasculature with.ill-deffinition of the heart margins likely basis of pulmonary edema.
Bilateral small pleural effusions within major.fissures demonstrated on the lateral xray. No pneumothorax.
