Electronic health records were queried to obtain demographic and clinical variables.

In-hospital death was reported in 14 patients (5.67%), while recurrent pericardiocentesis in 24 patients (9.72%). Iatrogenic cause was the most common etiology (42.5%), followed by neoplastic disease (23.1%) and idiopathic effusion (14.57%).
