I can understand your concern. In my he is having recurrent pericardial effusion. And his pericardial effusion consume blood, so he is requiring blood transfusion. Common causes for such recurrent pericardial effusion are infection like tuberculosis and malignancy. If we dont treat underlying pathology, this fluid will accumulate and may endanger life. So better to get done repeat thoracentesis and get done fluid reports for tuberculosis and malignancy. If it is tubercular then anti-tubercular Chat Doctor. But if it is malignant then he will need pigtail catheter insertion in pericardium. Diuretic works only in transitive fluid. So better to consult cardiologist and rule out tuberculosis and malignancy. Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks.
