Paediatric cardiac tamponade requiring pericardiocentesis: aetiology and age distribution of 252 patients in a tertiary single-centre cohort

To the best of our knowledge, this study represents the largest single-centre cohort of paediatric cardiac tamponade requiring pericardiocentesis. Cardiac causes, particularly structural heart diseases, represent the most common aetiology across all age groups; therefore, these patients should be promptly evaluated for cardiac tamponade when presenting with relevant symptoms.
