Use of Idarucizumab to reverse the anticoagulant effect of dabigatran in cardiac transplant surgery. A multicentric experience in Spain

Abstract

Background: Anticoagulation in heart transplant (HT) recipients increases the risk of hemorrhagic complications, so correct reversal of anticoagulation is needed. Dabigatran, a direct thrombin inhibitor, is increasingly used for anticoagulation in patients with non-valvular atrial fibrillation (NVAF) whose effect can be reversed by idarucizumab.

Aim: To present a nationwide experience using idarucizumab for the urgent reversal of dabigatran before HT.

Methods: Multicenter observational study in 12 Spanish centers to analyze the clinical outcomes after using idarucizumab before HT surgery.

Results: Fifty-three patients were included (81.1% male). 7.5% required re-operation in the immediate postoperative period to control bleeding and 66% transfusion of blood products. Median length of stay in the intensive care unit was 6 days and total hospital stay 24 days. 30-day survival was 92.4%. There were four deaths in the first month, all in the first 5 days post-HT. Only in one patient (transplanted due to a congenital heart disease, after sternotomy) who had surgical problems and right ventricular failure post-HT death was associated with bleeding.

Conclusions: These results may support the use of dabigatran as an alternative to vitamin K antagonists in patients listed for HT requiring anticoagulation due to NVAF. More studies are needed to reaffirm these observations.

Keywords: dabigatran; heart transplant; idarucizumab.
