Pericardial effusion can be treated with percutaneous fluid drainage, particularly in cases where there is a significant amount of fluid. However, for minor effusions, it is advisable that patients temporarily observe their condition and focus on symptomatic treatment. These small amounts of pericardial effusion can be absorbed naturally, and this typically pertains to milder cases. It is also recommended that patients regularly visit the hospital for echocardiography to monitor their condition. If the pericardial effusion does not fully resolve, fluid drainage may sometimes be necessary to alleviate the patient's current condition, as this fluid generally represents an inflammatory exudative change.
