Intra-pericardial thrombin injection as bailout strategy in iatrogenic pericardial tamponade.

ABSTRACT:

Background

Cardiac tamponade is a rare but life-threatening complication of cardiac interventions. Despite prompt pericardiocentesis, clinical management can be challenging and sometimes haemodynamic stabilisation is difficult to achieve. Intra-pericardial thrombin injection after pericardiocentesis promotes haemostasis and acts as a sealing agent, as previously described for left ventricular free-wall rupture. We aimed to evaluate intra-pericardial thrombin injection as a bailout strategy for pericardial tamponade following percutaneous cardiac interventions.

Methods

In a 5-year single-centre retrospective analysis we identified 31 patients with cardiac tamponade due to percutaneous intracardiac procedures. Intra-pericardial thrombin injection as a bailout strategy was administered in 5 of 31 patients (16.1%).

Results

Patients receiving intra-pericardial thrombin were in a more critical state when thrombin was applied, as demonstrated by a higher rate of resuscitation (40% versus 26.9%) and a trend toward a prolonged stay in the intensive care unit (177.6 ± 84.0 vs 98.0 ± 31.4 h). None of the patients with pericardial tamponades treated with intra-pericardial thrombin needed cardiothoracic surgery. Mortality after 30 days was lower with intra-pericardial thrombin injection than with standard treatment (0% vs 15.4%). We observed no complications using intra-pericardial thrombin.

Conclusion

Intra-pericardial thrombin injection could be considered as a bailout strategy for patients with iatrogenic pericardial tamponade due to percutaneous procedures. We recommend further evaluation of this technique in the clinical management of refractory pericardial tamponade.
