Blind subxiphoid pericardiocentesis involves inserting a needle through the subxiphoid area to access the pericardial space without the need for imaging guidance. This can provide rapid symptom relief in acute situations and can also help determine the nature of the effusion by allowing sampling of the fluid.

While radiation therapy and chemotherapy are important treatment modalities for malignancies that may contribute to pericardial effusions, they do not directly address the effusion itself. These treatments are aimed at reducing tumor burden or controlling disease progression, which may ultimately help in reducing the effusion over time, but are not immediate interventions for fluid removal.

Surgical removal of the heart is not a viable treatment option for pericardial effusions and is not performed in clinical practice;
