Use of idarucizumab for dabigatran reversal in cardiac tampo
It is known that the efficacy of catheter ablation for atrial fibrillation (AF) is high, but cardiac tamponade may occur in 1–2% cases. Even in such cases, fatal condition can be avoided by appropriate drainage, but reversal of anticoagulation therapy might also be necessary. Here, we report a case of use of idarucizumab for cardiac tamponade during AF ablation.

Although the drainage with pericardial centesis should be selected, we could not perform because echo free space was too thin at least at the precordial or apical side of the ventricle. Fortunately, dabigatran reversal by idarucizumab suppressed cardiac tamponade progress and the patient recovered without undergoing any invasive procedures. The pericardial drainage must be the principal therapy for cardiac tamponade, but reversal of anticoagulant might be helpful for patients’ recovery. It might be thought that dabigatran, the only direct oral anticoagulant with a specific reversal agent, should be the safest choice in case of risk for bleeding complications such as AF ablation.
