Idarucizumab in Emergent Pericardiocentesis: A Case Report of Dabigatran-Induced Haemopericardium and Cardiac Tamponade

Haemopericardium has rarely been described in association with the use of a non-vitamin K antagonist oral anticoagulant. Cardiac tamponade is a life-threatening condition that usually requires urgent pericardiocentesis. Here, the authors report a case of haemopericardium with cardiac tamponade during dabigatran therapy for atrial fibrillation in a patient with chronic coronary syndrome, treated effectively with reversal agent idarucizimab before pericardiocentesis. To the authors’ knowledge, this is only the third report of dabigatran-induced haemopericardium.
