When should pericardiocentesis be performed?

Pericardiocentesis is indicated for cardiac tamponade (hemodynamic compromise), large effusion (>20mm) with suspected bacterial/TB/malignant etiology, or large symptomatic effusion not responding to NSAIDs/colchicine.

How is pericardial effusion size graded?

Pericardial effusion: small 20mm. Tamponade physiology (RA/RV diastolic collapse, respiratory variation >25%) can occur even with moderate effusions.

What is the ESC recommendation for drainage timing?

ESC pericardial disease guidelines recommend: urgent drainage for tamponade (Class I), drainage for large effusions (>20mm) after 3 months of conservative therapy (Class IIa). Subxiphoid approach preferred.

Infective Pericarditis Effusion Drainage Threshold

Determine drainage threshold for pericardial effusion in infective pericarditis. Large effusion (>20mm echo-free space), tamponade features, or purulent etiology mandate pericardiocentesis.

How to Use

Enter the values for the scenario you are assessing. Determine drainage threshold for pericardial effusion in infective pericarditis. Large effusion (>20mm echo-free space), tamponade features, or purulent etiology mandate pericardiocentesis. Use the pericarditis drainage threshold result to inform your calculation.
