Bivalirudin is a direct thrombin inhibitor that is increasingly used in patients undergoing mechanical circulatory support as it presents many advantages compared with unfractionated heparin. The aim of this study was to describe our experience with bivalirudin as primary anticoagulant in patients undergoing ventricular assist device (VAD) implantation. An observational study was performed on 12 consecutive patients undergoing VAD implantation at our institution. ⋯ Bivalirudin is a valuable option for anticoagulation in patients with a VAD and can be easily monitored with aPTT. The use of a bivalirudin-based anticoagulation strategy in the early postoperative period may overcome many limitations of heparin and, above all, the risk of HIT, which is higher in patients undergoing VAD implantation. Bivalirudin should no longer be regarded as a second-line therapy for anticoagulation in patients with VAD.
